Question

Which statement best compares the momentum of a stationary truck and a car in motion? The moving car has less momentum than the stationary truck. The moving car and the stationary truck have the same momentum. The moving car has some momentum, but the stationary truck has none. The stationary truck has momentum, but it is less than that of the moving car.

Answer 1

The moving car has some momentum, but
the stationary truck has none.

Momentum of any object is (mass) times (speed).
If the object isn't moving then it has no speed,
and its momentum is zero, no matter how much
mass it may have.

Answer 2

Car has some momentum but truck has none

Step-by-step explanation:

Momentum is the measure of motion of body.

Momentum is defined as the product of mass of body and the velocity of the body. It is a vector quantity and it's SI unit is kg m /s.

Car is moving so it has mass and velocity both.

Thus car has some mass omen tum.

Truck is not moving it means the velocity of truck is zero.

Thus the momentum of truck is zero.
