An impulse occurs when is acting upon an object for a given amount in order to cause a change

Answer

Correct answer is  Force, Time and momentum

An impulse occurs when a force is acting upon an object for a given amount of time in order to cause a change in momentum

Explanation

Impulse in a body occur when a certain amount of force is applied on it for a given amount of time due to which momentum of body changes.

Hope it will help you

Force, time, and momentum.

Explanation

An impulse occurs when a force is acting upon an object for a given amount of time in order to cause a change in momentum.  When a force acts on an object for a short amount of time, an impulse is the measure of how much the force changes the momentum of an object.

Impulse= force x time

In short, if any object is subjected to certain amount of force at some given amount of time. This is called impulse.
