Practice Momentum in Physics

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

The product of an object's mass and velocity, representing the quantity of motion it carries.

How hard it is to stop something moving. Heavy and fast = lots of momentum.

Example 1

easy
A 2 \text{ kg} ball moves at 5 \text{ m/s}. What is its momentum?

Example 2

medium
A 1500 \text{ kg} car moving at 20 \text{ m/s} and a 0.05 \text{ kg} bullet moving at 600 \text{ m/s}. Which has greater momentum?

Example 3

easy
What velocity must a 0.5 \text{ kg} ball have to possess a momentum of 15 \text{ kg m/s}?

Example 4

medium
A 1200 \text{ kg} car moves east at 25 \text{ m/s} while a 1000 \text{ kg} car moves west at 10 \text{ m/s}. What is the total momentum of the two-car system?
