MECHANICS : MOTION - Conservation of Linear Momentum
In a rocket launch, the principle of conservation of momentum is demonstrated by:
The total mass of the rocket decreasing.
The expulsion of gases from the rocket engine.
The acceleration of the rocket due to thrust.
The increase in speed as fuel burns.
Which of the following is true about elastic collisions?
The objects stick together.
Kinetic energy is conserved.
Some kinetic energy is lost.
Momentum is not conserved.
If a 5 kg object is moving with a velocity of 10 m/s, what is its linear momentum?
500 kg·m/s.
50 kg·m/s.
5 kg·m/s.
10 kg·m/s.
Which of the following situations is a real-life application of the conservation of linear momentum?
A soccer ball being kicked by a player.
A car accelerating on a highway.
A moving object coming to rest due to friction.
A spaceship using its thrusters to change direction.
What is the momentum of a stationary object?
It depends on the mass.
It is equal to the object’s velocity.
It is equal to the object’s weight.
Zero.
