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
easyA 2 \text{ kg} ball moves at 5 \text{ m/s}. What is its momentum?
Example 2
mediumA 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
easyWhat velocity must a 0.5 \text{ kg} ball have to possess a momentum of 15 \text{ kg m/s}?
Example 4
mediumA 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?
