Work energy and power formulas pdf.
Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.
Here θ is the angle between and.
This signifies when the force and displacement are in same.
Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat.
H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring.
Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive.
Work work done w is defined as the dot product of force f and displacement s.
