is equal to the work done by the forces acting on the particle. These forces can either be conservative or non conservative. The force F(t) is the resultant of these forces. If gravity is acting on the particle, the work done by gravity is given by Where: ...
If we want to use the formula of work, we need the friction coefficient to calculate the frictional force. But that is not given. So let's attempt to implement the work-energy theorem. Forces acting on the block are gravity, normal reaction, and frictional force. So, Wf + WN + Wg =...
the work done isW=fdcos θ. Work done on a body is accomplished not only by a displacement of the body as a whole from one place to another but also, for example, by compressing agas, by rotating a shaft, and even by causing invisible motions of the particles within a body by an ...

Q.1. When a body falls freely under gravity, the work done by gravity is positive or negative? If a force is acting on a body that has a component in the direction of displacement, then the work done by the force is positive. Therefore, when a body or an object falls freely under ...
The displacement is upward and the force (gravity) is in the downward direction. Fluid resistance to flow, viscosity, is an example of negative work. Pushing an object on a rough surface. The frictional force and the displacement are in opposite directions. Kicking a ball in motion. Negative...
When we lift a load through a height against the force of gravity by applying a force greater than the gravitational force, the work done on the body is eventually stored as the gravitational potential energy of the body. This brings us to the work-energy theorem. Work energy theorem states...
Throwing an object in the air. The displacement is upward and the force (gravity) is in the downward direction. Fluid resistance to flow, viscosity, is an example of negative work. Pushing an object on a rough surface. The frictional force and the displacement are in opposite directions. ...
Gravity is another conservative force. The work done by gravity when you move from one point to another depends on the height difference, not on how you go from one point to another. With electrostatics replace "height difference" with "potential difference". It's the same idea. For this ...
