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 10
A 0.2 kg ball moving at 5 m/s collides elastically with a 0.2 kg ball at rest. What is the velocity of the first ball after the collision?
A 1 kg ball moving at 4 m/s collides with a 2 kg ball moving at -2 m/s. If the collision is perfectly elastic, what is the velocity of the 1 kg ball after the collision?
A 1.5 kg ball moving at 3 m/s collides with a 0.5 kg ball at rest. If the collision is perfectly inelastic, what is their velocity 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 2 kg ball moving at 8 m/s collides with a 2 kg ball moving at -4 m/s. If the collision is perfectly elastic, what are their velocities after the collision?
A 3 kg object moving at 6 m/s collides with a 2 kg object at rest. If they stick together, what is their velocity after the collision?
A 4 kg object moving at 2 m/s collides elastically with a 2 kg object at rest. What is the velocity of the 2 kg object after the collision?
A 5 kg cart moving at 2 m/s collides and sticks to a 3 kg cart at rest. What is their common velocity after the collision?
Describe what happens in a two-dimensional collision.
Describe what happens to the kinetic energy in a perfectly inelastic collision.
Describe what is meant by a 'one-dimensional collision'.
Explain the difference between elastic and inelastic collisions.
Explain why airbags are used in cars in terms of momentum and collisions.
Explain why kinetic energy is not conserved in inelastic collisions.
State the law of conservation of momentum.
What is meant by the term 'collision' in physics?
