Sample Question 2
DESCRIBE THE INTERCHANGE BETWEEN KINETIC ENERGY AND POTENTIAL ENERGY DURING SHM.

The interchange between kinetic energy and potential energy remains constant during SHM.

Kinetic energy is always zero during SHM.

Potential energy is highest at the top of the swing during SHM.

Kinetic Energy The kinetic energy is a maximum when the bob is travelling fastest; this is at the bottom of the swing. At the top of the swing, the bob is stationary, so the KE is zero. Potential Energy The potential energy is a minimum when the bob is at its lowest point; we take this to be zero. At the top of the swing, the potential energy is a maximum value. Total EnergyIf no energy is lost then the total energy is a constant value. When the bob is swinging, the energy continually changes between kinetic and potential.

Sample Question 3
State what is meant by damping.

A. Damping: a force that increases the energy of a system through motion.

B. Damping: a force that acts to stabilize the oscillations in a system.

C. Damping: a force that has no impact on the energy or amplitude of a system.

Damping: a dissipative force acts on a system in the opposite direction of motion of the oscillating particleEffect of damping: system loses energy and amplitude
