Explanation:

There are two conditions that must be met for an object to be in equilibrium. The first condition is that the net force on the object must be zero for the object to be in equilibrium. If net force is zero, then net force along any direction is zero. Kinetic energy (KE) is the energy of motion, and kinetic energy is not always conserved in a collision Energy and momentum are always conserved.
