Free fall and the acceleration due to gravity

Problem/Question: How do you measure the acceleration of a falling object?

Hypothesis: by measuring velocities of a falling ball then applying the data into equations numerous times, the results should approach to the acceleration.

Variables: A: Independent Velocity B:Dependant Acceleration C:Constant Distance (photo gates)

Materials: Photo gates, Clay ball, Photo gates machine.

Experimental Setup:

Procedure: 1) Set second photo gate 50 cm. from the first photo gate which will be 10cm. (second hole) from the bottom of the tower. 2) Connect the photo gate that is on top to number 1 and the photo gate that is on the bottom to number 2. 3) Place clay ball directly above first photo gate and drop. 4) Record results and repeat five times.

Data:

Observations:
1) The ball changes every time that is dropped
2) The ball is dropped in a different manner every time.
3) The time the ball takes to drop changes every time.

Conclusion:
How do you measure the acceleration due to gravity? The data showed that the times are never the same, but they are close enough. My hypothesis was correct because this method can be used to measure free fall and the acceleration due to gravity. The problem I had with this lab was that the balls where dropped in a different way every time which would yield varying results. The next time I perform this lab I would try to drop the ball the same way.

    Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts…

    Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity, g, was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317, which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop…

    experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration, which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment, a vertical stand with an electromagnet at the top for holding and then releasing of the falling body, called the plummet. The plummet falls between two vertical…

    value of acceleration due to gravity on the surface of the earth, and I have used this as the basis of my assessment. The value of acceleration due to gravity at the surface of the earth is 9.8 m/s/s. A value for acceleration due to gravity can be measured by observing the motion of a simple pendulum. The aim of my investigation is to determine whether the length of string used for a simple pendulum, affects the simple pendulums capacity to define the value of acceleration due to gravity. The simple…

    accepted value of acceleration due to gravity is . In this activity, an air-cart’s motion will be graphically analyzed. A mass will be attached to the air-cart by a string and hung over pulley with the other end attached to an air-cart resting on a frictionless surface. The study of the motion of the system of masses will be used to determine the velocity of the masses from an analysis of the displacement versus time data. This velocity will then be used to calculate the acceleration of the system…

    Measurement of Free-Fall Acceleration Introduction Galileo Galilei (1564-1642), the man first accredited with the correct notion of free-fall with uniform acceleration, stated that 'if one were to remove entirely the resistance of the medium, all materials would descend with equal speed.' Today, this statement holds true for all objects in free-fall near the Earth's surface. The purpose of this experiment is to verify Galileo's assertion that acceleration is constant. In addition, the magnitude…
