Kinetic energy depends on which two variables?

Kinetic energy is defined as the energy possessed by an object due to its motion. The formula for kinetic energy is given by:

[ KE = \frac{1}{2} mv^2 ]

In this equation, ( m ) represents the mass of the object, and ( v ) represents its velocity. This indicates that kinetic energy directly depends on the mass of the object and the square of its velocity. As either mass or velocity increases, the kinetic energy of the object also increases.

The other mentioned variables and relationships, such as those related to density, height, force, and acceleration, do not directly determine kinetic energy. For instance, density is a measure of mass per unit volume and does not have a relationship with the energy an object has in motion. Height refers to gravitational potential energy rather than kinetic energy, while force and acceleration relate more to Newton's laws of motion than the specific energy associated with an object’s movement. Therefore, mass and velocity are the key components in determining an object's kinetic energy.
