Question

1. what is kinetic energy? 6. what is potential energy?

Explanation:

Kinetic energy is the energy of motion. An object in motion has kinetic energy which depends on its mass and velocity, calculated by the formula $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. Potential energy is stored energy. Gravitational potential energy for example is given by $PE = mgh$ (where $m$ is mass, $g$ is gravitational - acceleration, and $h$ is height), and elastic potential energy in a spring is $PE=\frac{1}{2}kx^{2}$ (where $k$ is the spring - constant and $x$ is the displacement from equilibrium).

Answer:

Kinetic energy is the energy an object possesses due to its motion. Potential energy is stored energy, which can be gravitational (due to height), elastic (in a stretched or compressed spring), etc.
