How does impulse affect an object's momentum?

Impulse changes an object's momentum by applying a force over a specific period of time.

Impulse is a concept in physics that describes the change in momentum of an object when a force is applied over a period of time. It is calculated by multiplying the force applied to the object by the time over which the force is applied. This is represented by the formula: Impulse = Force x Time.

Momentum, on the other hand, is a measure of the motion of an object and is calculated by multiplying the object's mass by its velocity. The formula for momentum is: Momentum = Mass x Velocity.

When an impulse is applied to an object, it changes the object's momentum. If the force is applied in the same direction as the object's motion, it increases the object's momentum. If the force is applied in the opposite direction, it decreases the object's momentum. The greater the impulse, the greater the change in momentum.

For example, when a cricket player hits a ball, they apply a force to the ball over a short period of time. This force changes the ball's momentum, causing it to move in the direction the player hit it. The harder the player hits the ball (the greater the force), and the longer the contact time, the greater the change in the ball's momentum.

In summary, impulse is a crucial concept in understanding how the momentum of an object can be changed. By applying a force over a period of time, the momentum of an object can be increased or decreased, depending on the direction and magnitude of the force.
