Uniform Rectilinear Motion (Kinematics)

Uniform Rectilinear Motion (URM) : motion of an object in a straight track with constant velocity (constant speed and direction).

v = velocity (m/s)

x = displacement (meter)

t = time (second)

Uniform Rectilinear Motion experiment

Step of experiment: (It takes precision and accuracy in measurement)

1. Prepare equipment that supports the virtual laboratory experiment.
2. Calculate the time required for the green ball do 5 times collision. Write down the measurement

    in the tables provided. Do the experiment 3 times.
3. Do steps 2 for blue balls. (Do distribution tasks to each group member)

Table of measurement results. Then calculate velocity and average velocity.

Ball	Experiment	Number of collision (multiplied by 1 meter.)	Time (second)	Velocity (m/s)	Average velocity (m/s)
Green	I	5
	II
	III
Blue	I	5
	II
	III

Answer the question below :
1. What is stated that the green balls and blue balls indicate uniform rectilinear motion?
2. Which ball is faster? Explain!
3. Make the conclusions of the experiment!
