Newton`s Second Law of Motion
... Or does the force just change the velocity? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one. A Force Sensor and an Accelerometer will let you measure the force on a cart simultaneously ...
