The first experiment has a cart with a force sensor on it traveling towards a cart with its spring extended. The cart makes contact with the spring, the spring applies an impulse to the cart with the motion detector on it and sends it back the way it came. Logger Pro was used to measure the magnitude of the push and the time the push was applied for. An impulse is defined as the sum of the forces applied to an object times the amount of time applied for. In the case of this cart, the only force on the cart was the spring that pushed it away as all other forces either canceled out or were negligibly small.
