Question

categorization 1 point
compare and contrast potential and kinetic energy by placing all of the following in the correct category
kinetic energy only
potential energy only
kinetic and potential energy
possible answers
can be transferred
stored energy
height
gravity
motion energy
velocity
mass

Explanation:

• Can be transferred: Both kinetic and potential energy can be transferred. For example, in a pendulum, potential energy is transferred to kinetic energy and vice - versa.
• Stored Energy: Potential energy is stored energy. For instance, a compressed spring has elastic potential energy (stored energy) due to its deformation.
• Height: Potential energy (gravitational potential energy, \(U = mgh\)) depends on height. The higher an object is above the ground (in a gravitational field), the more gravitational potential energy it has.
• Gravity: Gravitational potential energy depends on the force of gravity. The formula \(U = mgh\) includes \(g\) (acceleration due to gravity).
• Motion Energy: Kinetic energy (\(K=\frac{1}{2}mv^{2}\)) is the energy of motion. An object in motion has kinetic energy.
• Velocity: Kinetic energy depends on velocity. As \(K=\frac{1}{2}mv^{2}\), an increase in velocity (while mass is constant) leads to an increase in kinetic energy.
• Mass: Both kinetic energy (\(K = \frac{1}{2}mv^{2}\)) and potential energy (in gravitational potential energy \(U=mgh\)) depend on mass.

Answer:

• Kinetic Energy Only: Motion Energy, Velocity
• Potential Energy Only: Stored Energy, Height, Gravity
• Kinetic And Potential Energy: Can be transferred, Mass
