Conservation of Momentum starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Conservation of Momentum.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A 0.2 kg ball is thrown at 15 m/s. What is its momentum?
A 1 kg ball moving at 2 m/s collides with a 2 kg ball at rest. If the 1 kg ball comes to rest after the collision, what is the velocity of the 2 kg ball?
A 1 kg ball moving at 5 m/s collides head-on with a 1 kg ball moving at -3 m/s. What is the total momentum before the collision?
A 10 kg object at rest explodes into two pieces: one of 6 kg moves at 4 m/s to the right. What is the velocity of the other piece?
A 2 kg ball is moving at 3 m/s. What is its momentum?
A 2 kg object moving at 5 m/s collides with a 3 kg object at rest. If they move together after the collision, what is their final velocity?
A 2 kg object moving at 8 m/s collides with a 4 kg object at rest. If they stick together, what is their final velocity?
A 3 kg cart moving at 4 m/s collides with a stationary 2 kg cart. If they stick together after the collision, what is their combined velocity?
A 3 kg object moving at 6 m/s collides with a 2 kg object moving at -4 m/s. What is the total momentum before the collision?
A 4 kg object moving at 3 m/s collides with a 2 kg object moving at -2 m/s. What is the total momentum after the collision if no external forces act?
A 5 kg object moves at 2 m/s to the right. What is its momentum?
Describe the difference between elastic and inelastic collisions in terms of momentum and kinetic energy.
Describe what happens to the momentum of a system if an external force acts on it.
Explain why momentum is conserved in a system with no external forces.
If a moving object collides with a stationary object of equal mass and sticks to it, what happens to their speed after the collision?
If the total momentum before a collision is 12 kg·m/s, what must the total momentum be after the collision (assuming no external forces)?
Momentum is a vector quantity. What does this mean?
What is the law of conservation of momentum?
A 0.2 kg ball moving at 8 m/s collides with a 0.3 kg ball at rest. After the collision, the 0.2 kg ball moves at 2 m/s in the same direction. What is the velocity of the 0.3 kg ball after the collision?
A 0.4 kg ball is at rest. A 0.6 kg ball moving at 5 m/s collides with it and they stick together. What is their velocity after the collision?
