Question
Indicate true or false in the following statements:
True Or False Momentum is conserved in all collisions.
True Or False The velocity of either partner in a perfect inelastic collision is the same as the velocity of their center of mass.
True Or False For a pair of colliding particles, if there was zero total momentum in the x direction before a collision there will be zero after.
True Or False In an elastic collision only momentum is conserved.
True Or False In a perfect elastic collision the two partners have the same final velocity.
Explanation / Answer
Momentum is conserved in all collisions -True.
The velocity of either partner in a perfect inelastic collision is the same as the velocity of their center of mass-True.
Because after collision in inelastic, both objects are moving with combined velocity.
For a pair of colliding particles, if there was zero total momentum in the x direction before a collision there will be zero after-True : From the law of conservation of momentum along x-direction.
In an elastic collision only momentum is conserved-False : In an elastic collision, both momentum and energy should be conserved.
In a perfect elastic collision the two partners have the same final velocity-False. The velocities of two particles may changes after collision.
