Potential

Recently we learned about kinetic energy (energy of motion).

A system of objects may also contain stored energy, also known as potential energy, depending on their relative positions. As you can see on the energy graph, an object has more potential energy if it is positioned higher. In other words, the skater has more potential energy at the top of the ramp.

Observe the model to answer the following question: Which of the following statements is true about the skater’s potential energy?

• The skater gains potential energy as he travels down the ramp.

• The skater loses potential energy as he travels down the ramp.

Which statement accurately describes potential and kinetic energy in the system?

• As the skater gains kinetic energy, they gain potential energy.

• As the skater gains kinetic energy, they lose potential energy.

Potential energy is stored energy. Objects that are higher up have more potential energy than objects that are lower (if both objects have the same mass). If two objects have different masses, the more massive objects has more potential energy (if they are are at the same height).
