The concept of conservation of momentum is a fundamental principle in physics, which states that the total momentum of a closed system remains constant over time, regardless of any internal interactions or external forces. To help students understand and apply this concept, we have compiled a comprehensive worksheet with answers in PDF format.
What is Conservation of Momentum?
Conservation of momentum is a fundamental principle in physics that states that the total momentum of a closed system remains constant over time. This means that the total momentum of a system before a collision or interaction is equal to the total momentum after the collision or interaction. The momentum of an object is calculated by multiplying its mass by its velocity.
Conservation of Momentum Equation
The conservation of momentum equation is given by:
m1v1i + m2v2i = m1v1f + m2v2f
where:
- m1 and m2 are the masses of the two objects
- v1i and v2i are the initial velocities of the two objects
- v1f and v2f are the final velocities of the two objects

Sample Problems and Answers
Here are a few sample problems and answers from the worksheet:
- A 1000 kg car is traveling at a speed of 20 m/s. If it collides with a 2000 kg truck that is at rest, what is the final velocity of the car and truck?
- A baseball player throws a ball with a mass of 0.5 kg at a speed of 25 m/s. If the ball is caught by a player with a mass of 50 kg, what is the final velocity of the player and ball?
- A 500 kg satellite is traveling at a speed of 1000 m/s. If it collides with a 2000 kg asteroid that is at rest, what is the final velocity of the satellite and asteroid?
Answers:
- v1f = 10 m/s, v2f = 5 m/s
- v1f = 0.5 m/s, v2f = 0.25 m/s
- v1f = 500 m/s, v2f = 250 m/s
