Free fall acceleration due to gravity is a concept that is fundamental to the study of physics. It refers to the rate at which an object falls towards the Earth due to the force of gravity. In this lab report, we will explore the concept of free fall acceleration and how it can be measured using a simple experiment.

To begin, we need to understand the basic principles of free fall. According to Newton's law of motion, an object in free fall experiences a constant acceleration of 9.8 m/s^2, also known as the acceleration due to gravity. This means that the speed of an object in free fall increases by 9.8 m/s every second.

To measure the free fall acceleration of an object, we can set up a simple experiment using a timer and a ruler. First, we need to select an object to drop, such as a small ball or a pencil. Next, we need to set up a timer to measure the time it takes for the object to fall a certain distance. Finally, we can use a ruler to measure the distance the object falls.

To perform the experiment, we first need to mark a starting point and a stopping point on the ruler. We can then drop the object from the starting point and start the timer as it falls. When the object reaches the stopping point, we can stop the timer and record the time it took for the object to fall. We can then use this time, along with the distance the object fell, to calculate the free fall acceleration.

To calculate the free fall acceleration, we can use the equation: acceleration = distance / time^2. Using this equation, we can plug in the values for distance and time that we measured during the experiment to determine the free fall acceleration of the object.

Overall, the concept of free fall acceleration due to gravity is an important one in the study of physics. By performing a simple experiment, we can measure the free fall acceleration of an object and understand how it is affected by the force of gravity. This understanding can then be used to make predictions about the motion of objects in a variety of situations, such as the trajectory of a projectile or the landing of a parachute.

Since there was an increase in the velocity of the object as it fell and since gravity is constant we can say acceleration was constant. If you begin to accelerate from rest at a constant acceleration, your speed increases continuously. Systematic errors may also have been associated with the instrument which may have affected the results. Method I produced a higher percentage difference because more readings were taken which led to more variations and errors being included in the calculations. With the assistance of my teacher I was shown an experiment that investigated the value of acceleration due to gravity on the surface of the earth, and I have used this as the basis of my assessment. Hypothesis It is hypothesized that the object that is dropped will endure gradual change acceleration in acceleration. We are trying to determine if the objects with heavier mass have a greater acceleration than those with a lighter mass.

However, if objects are physically larger or take on a flat shape, they will take a longer time to reach the ground due to the effects of air resistance. How do you know? The velocity-time graph is in a straight line, meaning it was going at a constant acceleration. Motion Sensor : Hang a motion sensor from the ceiling. Personal error may also have been an influencing factor on the results of this experiment as the markings produced on the waxed tape were very small and could have been misread while there distances were being measured. Every 6 th dot is 0. Acceleration can be caused by a change in speed or by a change in direction. It was heading in a positive direction refer to graph 1.

Acceleration Due to Gravity & Velocity of an Object in Free Fall Lab Answers

Equipment: The equipment used in this experiment is a free fall adapter ME-9207B, one small and one big steel balls, balance, 2m-meterstick, stand with a long rod, PASCO 850 interference and a computer. Afterwards, individually we analyzed the tape which had been marked into 6 dot intervals. Display and record the acceleration. Observations Time t s 0. Background Neglecting air resistance, an object falls a distance proportional to the square of the time.

Drop a ball and record the time with a stopwatch. In this experiment the relationship between distance and time is used to calculate the velocity of the object at each point. The timer was started and the mass was released. The change in the velocity of the object with respect to time can then be used to determine the acceleration of that object due to gravity. The magnitude of g at the Berks Campus is 9. The value of acceleration due to gravity is approximately 9. Repeat the same procedure Premium Error Scientific method Time Acceleration Due to Gravity Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? A free falling object has a constant acceleration of 9.

Each ball was dropped from a height of five feet and the amount of time it took to reach the floor was measured using a stopwatch. This acceleration of a falling object can be tested using a Behr Free-Fall apparatus to conduct a free fall experiment. Another systematic error is that the ruler is not 100% accurate when measuring; it may be off by. My hypothesis was only partially correct. Changing the time interval between sparks would not affect the slope of the graph, it may only cause the graph to be shifted to the left or to the right. In this laboratory we will investigate the acceleration due to the force of gravity on a falling object assuming that the only force acting on the object is gravity.

Picket Fence : Drop a Picket Fence a clear plastic strip with uniformly spaced opaque bands through a Photogate. By examining a graph of changes in velocity vs time, a more accurate value was observed. PRINT A GRAPH WITH THE EQUATION DISPLAYED FOR EACH PERSON IN YOUR GROUP. The calculation is very sensitive to the measured drop Premium Gravitation General relativity Force Calculating for Acceleration Due to Gravity with a Picket Fence in Free Fall Calculating for acceleration due to gravity using a picket fence in free fall R. Task 2 References Premium Pendulum Free Fall Lab Free Fall Lab Natalie Soria Lab Partners: Ryan Michaely Iqra Haji Yan Huang 1. Data Analysis and Discussion The results demonstrate that while the mass of the ball does not impact the amount of time it takes for the ball to reach the ground, the diameter of the ball has a small impact on this process. I measured and recorded the displacements corresponding to the 6 dot intervals in table 1.

I measured and recorded the position from the start of the tape corresponding to each half time interval and then plotted a velocity-position graph using the velocities I recorded. Conclusion All objects fall to the ground at the same acceleration, 9. It is directly proportional to the time. This experiment will help us to understand the concept of free fall on an object along with the acceleration. Materials â€” C Clamp â€” Metre-stick â€” Mass 50g â€” Cushion â€” Recording timer tape â€” Graph paper â€” Recording timer â€” Power supply â€” Long retort stand â€” Masking tape Procedure I used the table on the given lab sheet to design a table for my results. Each opaque band on the Picket Fence blocks the Photogate beam and the time from one blockage to the next becomes increasingly shorter.

Variables: a Independent- the length of the pendulum; b Dependent- the time it takes for 20 oscillations; c Control - the mass of pendulum. Knowing the distance 1 between the leading edge of each opaque band, Capstone calculates the acceleration of the picket fence. However, there are several factors that can impact this occurrence, including air resistance. Acceleration is represented by the formula:. Balls with a larger diameter fell more slowly due to a small amount of air resistance that was created during the free fall. Remember to attach a rubric to the end of your lab report. Due to a change in velocity, there was a change in displacement.

Solid gold ball H. This is a measure of your accuracy. Introduction: Gravity can be described as a force that causes two particles to be pulled towards each other. Acceleration was found by finding the slope of the velocity time graph. He asserted that for a given location on Earth, all objects fall with the same uniform acceleration. This effect is demonstrated in figure 1.

Purpose The purpose of this lab was to evaluate the increase in velocity with time during a free fall. The change in velocity of an object in free fall was directly proportional to the displacement. The hypothesis for this experiment is if an object falls freely, then the speed remains the same during its fall. It is important to consider that despite the size of the ball, it fell at an acceleration of 9. A graph of this equation would yield a parabolic curve as shown in the example below.
