Collisions starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Collisions.
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.
See sample questions for grade 11
A 0.5 kg ball moving at 2 m/s collides with a 0.5 kg ball moving at -1 m/s. If the collision is perfectly inelastic, what is their common velocity after the collision?
A 1 kg ball moving at 6 m/s collides elastically with a 2 kg ball at rest. What is the velocity of the 1 kg ball after the collision?
A 2 kg ball moving at 3 m/s collides head-on with a stationary 1 kg ball. If the collision is perfectly elastic, what is the velocity of the 1 kg ball after the collision?
A 3 kg cart moving at 4 m/s collides with a 2 kg cart at rest. If the collision is elastic, what is the velocity of the 3 kg cart after the collision?
A 4 kg object moving at 2 m/s collides with a 2 kg object moving at -1 m/s. If the collision is perfectly inelastic, what is their final velocity?
A 5 kg object moving at 3 m/s collides elastically with a 2 kg object at rest. What is the velocity of the 2 kg object after the collision?
Describe the difference between a head-on collision and a glancing collision.
Describe what happens to the kinetic energy in a perfectly inelastic collision.
Explain why momentum is conserved in collisions but kinetic energy may not be.
Explain why two objects of different masses do not necessarily have the same velocity after a collision.
State the law of conservation of momentum.
Two identical balls collide elastically. If the first ball is moving at 5 m/s and the second is at rest, what are their velocities after the collision?
What is the difference between an elastic and an inelastic collision?
