Question

If you kick a ball, you apply an impulse. The impulse is equal to

Answer 1

Answer:

The correct answer is b. The change in momentum of the ball.

Explanation:

When you apply a force on an object with a direction in a period of time, you are changing its amount of movement (momentum).

We know that force (F) is equal to the mass (m) multiplied by the acceleration (a):

F= m x a

If we multiply both members of the equation by the time (t), we obtain:

F x t = m x a x t

And we know that a x t = velocity (v), so:

F x t = m x v

F x t= impulse

m x v = momentum

So, the impulse is equal to the change in momentum of the object.
