Exploring Potential Energy Concepts MYP3.

Identify the type of energy stored in a stretched spring.

• Kinetic Energy

• Potential Energy

• Thermal Energy

• Chemical Energy

• The 2 kg object has more potential energy.

• The 4 kg object has more potential energy.

• Both have the same potential energy.

• Potential energy cannot be determined.

• 19.6 J

• 29.4 J

• 58.8 J

• 98.0 J

Describe what happens to the potential energy of an object as it is lifted higher above the ground.

• It decreases.

• It remains constant.

• It increases.

• It becomes zero.

List the factors that affect gravitational potential energy.

• Mass and speed

• Height and speed

• Mass and height

• Speed and temperature

Label the following as either potential energy or not potential energy: A book on a shelf, a moving car, a compressed spring.

• Potential energy, not potential energy, potential energy

• Not potential energy, potential energy, not potential energy

• Potential energy, potential energy, not potential energy

• Not potential energy, not potential energy, potential energy

Explain why potential energy is considered a form of stored energy.

• Because it is always in motion.

• Because it can be converted into kinetic energy.

• Because it is visible.

• Because it cannot be converted into other forms of energy.

Compare the potential energy of two identical objects, one at 10 meters and the other at 20 meters height.

• The object at 10 meters has more potential energy.

• The object at 20 meters has more potential energy.

• Both have the same potential energy.

• Potential energy cannot be determined.

Identify the formula for gravitational potential energy.

Explain what happens to the potential energy of an object when it falls to the ground.

• It increases.

• It remains constant.

• It decreases.

• It becomes infinite.
