Question

which term describes the energy of motion?
a. kinetic energy
b. elastic energy
c. electrical energy
d. gravitational potential energy

Explanation:

• Kinetic energy is the energy of motion. It depends on an object's mass and velocity ($KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity).
• Elastic energy is related to the deformation of elastic objects (e.g., a stretched spring).
• Electrical energy is associated with electric charges and electric fields.
• Gravitational potential energy is related to an object's height in a gravitational field ($PE = mgh$, where $m$ is mass, $g$ is acceleration due to gravity, and $h$ is height).

Answer:

A. Kinetic energy
