Question

Which of these statements is true about the effect of a force exerted upon an object?

A. A large force always produces a large change in the object’s momentum.
B. A small force always produces a large change in the object’s momentum.
C. A small force applied over a long time interval can produce a large change in the object’s momentum.
D. A large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.

Answer 1

D. A large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.

Step-by-step explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

`Momentum = mass * velocity`

Also, the impulse of an object is given by the formula;

`Impulse = force * time`

In accordance with the impulse-momentum theorem, the statement which is true about the effect of a force exerted upon an object is that a large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.
