The Work- Energy Theorem states that the work done on or by the body is equal to the change in its kinetic energy.
Consider a force F applied on the body of mass m moving on the horizontal frictionless surface.
Let after travelling a distances s, the velocity of body change from u to v.
The small amount of work, dW done by force F in displacing the body by ds is,
dW = 
dW = mv dv
Now, integrating both sides, we have
That is,
Work = Change in Kinetic energy.

Conservative forces are those for which work done depends only on initial and final points.
Example- Gravitational force, Electrostatic force.

Mourad kicked his heels into the horse and shouted, “Vazire run!” The horse stood on its hind legs, snorted, and ran forward at full speed. Mourad raced the horse across a field of dry grass to an irrigation ditch. He crossed the ditch on the horse. When he returned five minutes later he was dripping wet.

It seemed to him that stealing a horse for a ride was not the same thing as stealing something else, such as money. Since he and Mourad were quite crazy about horses, it wasn’t stealing. He convinced himself with the thought that it would become stealing only when they offered to sell it.

Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period. A frequently cited example of uniform acceleration is that of an object in free fall in a uniform gravitational field. One of the common examples of uniformly accelerated motion is freely falling bodies. The only acceleration which is acting on the body is g (acceleration due to gravity). A body has a uniform acceleration if it travels in a straight line and its velocity increases by equal amount in equal intervals of time. For Ex:Motion of freely falling body, bicycle going down the slope, ball rolling down in inclined plane.

The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Satellites are launched by taking them outside atmosphere, where atmospheric drag is negligible and giving them required velocity. This is usually done by rockets. Once in space, outside atmosphere, the spacecraft’s fuel is used to position the satellite in correct orbit and location.
