Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to themotionof the object, the work is considered to be negative, implying that energy is taken from the object. The units in wh...
Work Formula The formula for work done can be expressed mathematically as the dot product of force and displacement as, Work = Force x Displacement W = FdCosθ F cosθ is the component of force (F) in the direction of displacement (d) of the system. It can be positive, negative or ...
Work Done Formula The fundamental physical quantity of interactions between bodies is the force, while through interactions energy can be transferred between them. The amount of energy that is transferred through forces is called work and it is a physical quantity of energy with S.I. units of ...

If he pushes the lawn mower 30.0 m, how much work has been done to move the mower? Answer: The force is at an angle of 60.0° with respect to the movement. The work can be found using the formula: W = Fd cosθ W = Fd cos60° W = Fd(0.5) W = (900 N)(30.0 m)(0.5) ...
Q.2. What are the different units to express work? Answer. Work has the SI unit of Joule(J). 1 Joule is expressed as the work done when a force of 1 N applied on a body causes it to move through a displacement of 1 metre in the direction of the force. A calorie is also in ...
