## Impulse of object Formula and Calculation

When calculating the impulse of an object when hitting an unmoveable obstacle a positive number indicates movement to the right.

J = m × v0 - m × v

## Force of collision Formula and Calculation

You can calculate the force of collision when an object hits an unmoveable obstacle if the collision interval is available using the following equation:

F = m × v 0 - m × v/∆t
