Understanding Potential Energy

What is a key characteristic of potential energy?

• It is associated with a system of objects.

• It is only present in moving objects.

• It is always measured in watts.

• It is only associated with a single object.

How does gravitational potential energy change when an object is raised higher?

• It increases.

• It becomes zero.

• It remains the same.

• It decreases.

What is the first step in assigning a numerical value to gravitational potential energy?

• Assigning a zero point for potential energy.

• Measuring the object's speed.

• Calculating the object's mass.

• Determining the object's color.

What happens to electric potential energy when unlike charges are moved farther apart?

• It remains constant.

• It becomes negative.

• It increases.

• It decreases.

How can we assign a value to electric potential energy?

• By observing the color of the charges.

• By counting the number of charges.

• By choosing a reference point for zero potential energy.

• By measuring the temperature.

What is elastic potential energy fundamentally based on?

• Thermal energy.

• Gravitational potential energy.
