What type of energy is associated with an object's motion?

• Potential Energy

• Thermal Energy

• Kinetic Energy

• Chemical Energy

If the mass of a moving object is tripled and its speed is quadrupled, how much will its kinetic energy change from its original value?

• It will increase by a factor of 3.

• It will increase by a factor of 12.

• It will increase by a factor of 16.

• It will increase by a factor of 48.

A 10 kg ball is held 50 meters above the ground. What is its gravitational potential energy? (Use g = 9.8 m/s²)

• 490 J

• 500 J

• 4900 J

• 5000 J

What happens to the gravitational potential energy and kinetic energy of a ball as it falls from a height?

• Gravitational potential energy increases, kinetic energy decreases.

• Gravitational potential energy decreases, kinetic energy increases.

• Both gravitational potential energy and kinetic energy increase.

• Both gravitational potential energy and kinetic energy decrease.

What does a higher spring constant (k) indicate about a spring?

• The spring is more loose.

• The spring is more stiff.

• The spring has less elastic potential energy.

• The spring has a shorter natural length.
