Question

what is kinetic energy? what does kinetic energy depend on? what happens when one object has high mass, high speed? high mass, low speed? what happens when one object has low mass, low speed? low mass, high speed?

Explanation:

Kinetic energy is the energy of motion. It depends on an object's mass and speed. The formula for kinetic energy is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is speed. When an object has high - mass and high - speed, it has a large amount of kinetic energy. High - mass and low - speed still gives significant kinetic energy due to the mass factor. Low - mass and low - speed results in a small amount of kinetic energy, while low - mass and high - speed can still give a considerable amount of kinetic energy depending on the speed value.

Answer:

Kinetic energy is the energy of motion. It depends on mass and speed. High mass and high speed means high kinetic energy; high mass and low speed still gives significant kinetic energy; low mass and low speed means low kinetic energy; low mass and high speed can give considerable kinetic energy.
