Detailed explanation-1: -Work is done on an object when the object moves in the SAME direction in which the force is applied. If you pull at an angle instead of in the direction in which the object moves, MORE of your force does work. The FARTHER you move an object, the more work you do.
Detailed explanation-2: -Work is the force exerted on an object multiplied by the distance the object moves due to that force. The unit for work is called the joule, which is a kg m2/s2. If the force is at an angle to the motion, then the component of the force in the direction of the motion is used to determine the work done.
Detailed explanation-3: -Work is the use of force to move an object. It is directly related to both the force applied to the object and the distance the object moves. Work can be calculated with this equation: Work = Force x Distance. The force is expressed in Newtons (N), and distance is expressed in meters (m) to find the work in Joule (J).
