Momentum and Impulse

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.

• doubles.

• quadruples.

• decreases.

The impulse-momentum relationship is a direct result of Newton’s

• first law

• second law

• third law

• law of gravity

Two objects with the same mass will always have the same momentum.

• True

• False

A tiny bullet can have more momentum than a huge truck.

• True

• False

The impulse-momentum theorem originated from the what law of motion?

• Law of inertia

• Law of acceleration

• Law of interaction

• Law of Gravitation

The impulse-momentum theorem states that

• The impulse exerted on an object is greater than the object’s change in momentum

• The impulse exerted on an object is greater than the object’s change in momentum

• The impulse exerted on an object equals the object’s change in momentum

• The impulse exerted on an object equal to the product of the object's mass and force

The change in an object’s momentum is equal to

• the product of the mass of the object and the time interval.

• the product of the force applied to the object and the time interval.

• the time interval divided by the net external force.

• the net external force divided by the time interval

A large change in momentum over a long period of time requires a small force.

• True

• False

Which of the following equations can be used to directly calculate an object’s momentum?

• p = FΔt

• J = FΔt

• p = mv

• J=mv

The truck is moving at a slow rate of speed while the car is moving at a fast rate of speed which has the greater momentum?

• the truck

• the car

• Both

• None of the two
