Define work and calculate the work done if the direction of force and displacement is same, opposite, perpendicular to each other and at an angle.
- an object thrown at a certain angle to the ground moves in a second path and falls back to the ground the initial and the final point of the path of the object lies on the same horizontal line what is the work done by the force of gravity on the object?
- A car of mass 2 kg is moving with speed of 10m/s. Calculate work done to stop it ?
