Question	Answer
Work (W)	Product of Force and Displacemnt W=F*S If there is no force acting of the object then there is no work done on the object. If the force acting of the object cannot produce displacement, then there is no work done on the object.
Potential Energy (Gravitational)	Ep=mgh
Potential Energy (Elastic)	k: spring constant (N/m) x: displacement of distortion Image: 47df1566-8969-4fc9-a839-0fd72ab9cd54 (image/png)
Kinetic Energy	v: final velocity of the motion or the instantanous velocity of the moment which you wish to calculate for Ek Image: 18ef4460-87e6-48f8-8b4a-f0b3b71b9874 (image/png)
