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 12
A 0.1 kg ball moving at 5 m/s strikes a stationary 0.1 kg ball. If the collision is perfectly elastic, what is the velocity of the second ball after the collision?
A 0.2 kg ball moving at 10 m/s collides with a wall and rebounds with a velocity of -8 m/s. What is the coefficient of restitution?
A 0.5 kg ball moving at 6 m/s collides with a stationary 0.5 kg ball in a perfectly elastic collision. What is the velocity of the first ball after the collision?
A 1 kg ball moving at 2 m/s collides with a 2 kg ball moving at -1 m/s. If the collision is perfectly elastic, what is the velocity of the 1 kg ball after the collision?
A 2 kg cart moving at 3 m/s collides with a 1 kg cart at rest. If they stick together after the collision, what is their common velocity?
A 2 kg object moving at 3 m/s collides with a 2 kg object moving at -1 m/s. If the collision is elastic, what is the velocity of the first object after the collision?
A 3 kg object moving at 4 m/s collides with a 2 kg object moving at -3 m/s. If the collision is perfectly inelastic, what is their final velocity?
A 4 kg object moving at 5 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 object moving at 2 m/s collides elastically with a 3 kg object at rest. What is the velocity of the 5 kg object after the collision?
Define the coefficient of restitution.
Explain the difference between elastic and inelastic collisions.
If the coefficient of restitution is 0, what type of collision has occurred?
If two identical balls collide head-on elastically, what will be the velocities of the balls after the collision if their initial velocities were v and -v?
If two objects collide and move together as one mass after the collision, what type of collision is this?
In a two-dimensional collision, which components of momentum are conserved?
Two objects of masses 2 kg and 3 kg move towards each other with velocities 4 m/s and -2 m/s, respectively. If they collide elastically, what is the total momentum before the collision?
Which law is used to analyze collisions in mechanics?
A 0.4 kg puck slides on frictionless ice at 3 m/s and collides with a stationary 0.6 kg puck. After the collision, the 0.4 kg puck moves at 1 m/s in the same direction. What is the velocity of the 0.6 kg puck after the collision?
A 0.5 kg ball moving at 10 m/s collides elastically with a 1 kg ball at rest. What is the velocity of the 0.5 kg ball after the collision?
A 1.5 kg object moving at 4 m/s collides with a 2.5 kg object moving at 2 m/s in the same direction. If the collision is perfectly inelastic, calculate the loss in kinetic energy due to the collision.
