Impact force and collision time
To inject a given quantity of motion (momentum) into an object by impact, the force required is inversely proportional to the time of application.
In this simulation, the force applied by the machine is constant. To maximize the velocity, the contact time must be increased by dragging the ball to the left. What does the area of the graph below represent?
