How can you determine an object mechanical energy

Objects have mechanical energyif they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving car possesses mechanical energydue to its motion (kineticenergy).

Kinetic energy + potential energy

KE=1/2mv^2

PE=M*G*H
