4. Linear Momentum
Conservation Of Linear Momentum — Quiz
Test your understanding of conservation of linear momentum with 5 practice questions.
Practice Questions
Question 1
What does conservation of linear momentum mean for a closed system with no net external force?
Question 2
Which condition is needed for the momentum of a system to be conserved?
Question 3
A $2\,\text{kg}$ cart moving at $3\,\text{m/s}$ collides with a $1\,\text{kg}$ cart at rest. What is the total momentum before the collision?
Question 4
A ball of mass $0.5\,\text{kg}$ moving at $4\,\text{m/s}$ hits a ball of mass $0.5\,\text{kg}$ at rest. If the first ball stops after the collision, what is the total momentum of the two-ball system after the collision?
Question 5
Why can two objects in a collision have different final momenta even when total momentum is conserved?
