State the predicted height, taken from your graph, of the ping pong ball bounce when dropped from 4 m. Then draw a sketch of the ping pong ball at the top of its bounce (maximum height) and give your sketch a title. Use one or more labelled arrows to indicate any forces acting on the ball. Are there any balanced forces? Explain how you came to your decision. (Advisory word count: 50 words). Ball bounce forces at maximum height. Ball Center of gravity Gravity acceleration Based on Newton's three laws and the law of gravity law, when the ball bounces and reaches its maximum height, it is in a state of inertia. The force is balanced and has zero velocity. But the ball will still experience the force of gravity and, therefore, acceleration.
