PHYSICS Conservation of the Linear Momentum Remote Lab
PART 1.
Please carefully read the following examples and multiple choice problems. In
marking and typing in your answers, you are expected to use bold and colored
fonts on the following pages. If your electronic device allows for it, then you could
circle/mark the answers, too. Just distinctively mark your answers to all of the
following conceptual and computational exercises.
Please work on these practice exercises and answer to the fill-in-the-blanks questions
below. They prepare you for the following two sections of animated simulations
observations (in Part 2) and concluding computations (in Part 3.)
Let’s proceed:
A moving car has momentum. If it moves twice as fast, its momentum is twice as much.
Two cars move down a hill at the same speed. One car is twice as heavy and the other.
Compared to the lighter car, the heavier car’s momentum is twice as much.
A pellet gun shoots a pellet. The recoil momentum of the gun is same as the momentum of the
pellet that was fired.
Two balls, A and B are sitting on a table. Ball A is set in
motion with a pool cue while Ball B is at rest.
Ball A and Ball B collide
Ball B moves away from Ball A
a. Upon collision, the momentum of Ball A decreases.
b. Upon collision, the momentum of Ball B increases.
c. Upon collision, the momentum of both Balls stays the same.

The following is a Momentum Chart for the situation above which shows the momentum for
each of the balls before and after the collision. Calculate the change in momentum for the
System of the two balls. Remember to show all of your work that leads to the final
numerical values stored in the table of data that follows.
Before Collision
After Collision
Ball A
10
0
Ball B
0
10
Total

10
Answer:
Total momentum before collision= Momentum of ball A before collision+ Momentum of ball B
before collision
Total Momentum before collision = 10 + 0 = 10
Total momentum after collision= Momentum of ball A after collision + Momentum of ball B after
collision
Total momentum after collision = 0 + 10 = 10
Change in momentum of system of two balls= Total momentum after collision- Total momentum
before collision
Change in momentum of system of two balls = 10 -10 = 0
What is the impulse (change in momentum) of Ball A?
Answer:
Change in momentum of ball A = Momentum of Ball A after collision Momentum of Ball A
before collision
Change in momentum of Ball A = 0 10 = -10
What is the impulse on Ball B?
Answer:
Change in momentum of ball B = Momentum of Ball B after collision Momentum of Ball B
before collision
Change in momentum of Ball B = 10 0 = 10
