Lab #15
Unit #5
Momentum/Energy Lab
Pre Lab:
How do forces exerted on an object by another object change the linear momentum
of the object?
How are force and impulse related to conservation of linear momentum?
In a collision between two objects, how does the change in momentum compare for
each object? (justify using example calculations)
Goal: To Determine if momentum and energy is conserved in
each type of collision
Learning Objective (5.D.1.1)
The student is able to make qualitative predictions about natural phenomena
based on conservation of linear momentum and restoration of kinetic energy
in elastic collisions. (Science Practices 6.4 and 7.2)
You must collect data such that you have the ability to predict the velocity,
momentum, and energy of a cart after a collision.
Lab #15
Unit #5
Instructions:
Design a data table that accommodates data collection for 12 different collisions.
The data must include:




Velocity of each cart before/after
Mass of each cart before/after
Momentum before/after
Kinetic energy before/after
Must include the following types of collisions:
-Inelastic (Two objects collide to form one)
-Elastic (Two objects collide and remain two separate objects)
-Explosion (One object separates to form two objects)
