MECHANICS : MOTION - Conservation of Linear Momentum
Which of the following is an example of an inelastic collision?
A rocket accelerating in space.
Two cars colliding and sticking together.
A hockey puck sliding on ice.
A ball bouncing off a wall.
If a 2 kg object moving at 10 m/s collides with a stationary 3 kg object, and they stick together after the collision, what is their combined velocity?
6 m/s.
4 m/s.
2 m/s.
10 m/s.
What is the definition of linear momentum?
The product of velocity and time.
The product of mass and acceleration.
The product of mass and velocity.
The product of velocity and force.
The principle of conservation of linear momentum states that:
Total momentum is always conserved in a closed system.
Momentum of each object in a system is conserved.
Total momentum increases in an isolated system.
Momentum is conserved only when objects collide.
Which of the following is an example of a collision where momentum is conserved, but kinetic energy is not?
Two cars colliding and sticking together.
A ball bouncing off a wall.
Two identical balls bouncing off each other elastically.
A bullet fired from a gun.
