We are presenting Instantaneous Velocity and Uniform Acceleration

We are presenting: Instantaneous Velocity and Uniform Acceleration Motion in One Dimension Created By: • Mohammad Ali • Juan Viteri • Christina Suriel

Objective: • To investigate the relationship between instantaneous velocity and average velocity. • To measure the acceleration of a body and verify the kinematics equation for uniformly acceleration motion.

Equipments: • Air track with glider • Air supply • Set of cardboard flags of different length • Science workshop interface box • Two photo gates • Meter stick • Cylinder or block

Motion and Displacement: Positive direction Negative direction The Motion is a along straight line only Displacement is an example of a vector quantity

Experiment #1: Determination of the instantaneous velocity of a moving glider

Experiment #2: Measurement of the acceleration of the moving glider and verification of the kinematics equations.

Conclusion: In this experiment, we investigated the relationship between instantaneous velocity and the average velocity. The purpose of this experiment was to measure the average velocities of the moving glider, which was on an inclined air track, with a photogate timer. We repeated this process for all five flags of different lengths. We concluded that the longer the flag was, the smaller the approximation. Furthermore, by using the equations and equipment, we were able to fully understand appreciate this experiment.
