What type of energy is at its maximum when a pendulum is at the highest point of its swing?

• Kinetic energy

• Potential energy

• Thermal energy

• Electrical energy

What is the formula for kinetic energy?

• E_k = mgh

• E_k = ½ mv²

• E_k = mv

• E_k = 2mgh

At what point in its swing does a pendulum have maximum kinetic energy?

• At the highest point

• At the lowest point

• At the midpoint

• At the starting point

What is the formula for potential energy?

• E_p = ½ mv²

• E_p = mgh

• E_p = mv

• E_p = 2mgh

What happens to the potential energy of a pendulum as it swings from the highest point to the lowest point?

• It increases

• It decreases

• It remains constant

• It becomes zero

What is the relationship between maximum potential energy and maximum kinetic energy in a pendulum?

• E_p,max = E_k,max

• E_p,max > E_k,max

• E_p,max < E_k,max

• E_p,max = 0

When is the kinetic energy of a pendulum zero?

• At the lowest point

• At the highest point

• At the midpoint

• At the starting point

What does the variable 'h' represent in the potential energy formula E_p = mgh?

• Mass

• Height

• Velocity

• Energy

According to Hooke's Law, what is the relationship between the displacement of a material and the applied force?

• Displacement is inversely proportional to force

• Displacement is equal to force

• Displacement is proportional to force

• Displacement is independent of force

In the formula F = -kx, what does the variable 'k' represent?

• Displacement

• Force

• Spring constant

• Mass
