1. Simple harmonic motion

2. Vibration… Equilibrium … Restoring force… Displacement…

3. There is a force that is trying to bring the ball back to its equilibrium What happens to the force as the angle is increased? What happens with the force as the object gets closer to equilibrium. There is the restoring force maximum? Where is acceleration maximum? Where does the restoring force = 0? Where does the acceleration = 0? Where is the speed at its maximum? Where is the speed at its minimum?
