Kinetic Energy
Kinetic energy is the energy of motion and is defined as the product of the mass of an object and its velocity squared. Mathematically, KE = ½mv², where:
KE is the kinetic energy in joules (J)
m is the mass in kilograms (kg)
v is the velocity in meters per second (m/s)
Potential Energy
Potential energy is the energy stored in an object due to its position or configuration. It is defined as the product of the force acting on an object and the distance through which the force is applied. Mathematically, PE = Fd, where:
PE is the potential energy in joules (J)
F is the force in newtons (N)
d is the distance in meters (m)
Work-Energy Theorem
The work-energy theorem states that the net work done on an object is equal to the change in its kinetic and potential energy. In other words, W = KE + PE, where W is the work in joules (J), KE is the kinetic energy in joules (J), and PE is the potential energy in joules (J).
This theorem implies that the total mechanical energy of an object remains constant, meaning that the total work done on the object must be zero for the object to reach a state of rest or constant velocity
