What is force? what is weight? what is speed? what is velocity? what is acceleration? what is work? what is energy? what is power?
Answers
1.Force: Any push or pull to change the state of a body , to stop a moving body, or to accelerate a body etc. is called force.
2.Weight: Force acting on a body.
weight=mass * force
3.Speed: Distance travelled by a body in unit time.
speed=distance /time
4.Velocity: Rate of displacement.
velocity =displacement / time
5.Acceleration:Rate of change of velocity.
acceleration=Final velocity - initial velocity /time
6.Work: force * displacement
7.Energy: Converted form of mass.
8.Power:Rate of doing work.
power=work /time
