force it is when we apply our muscle power to do something. example we apply force in pushing a car
WORK it is done when we apply force to move a thing . example we push an almirah and it moves
DISPLACEMENT it is a vector tht points initial position to final positon .
ACCELERATION rate at which object increases or decreases it speed
VELOCITY it is the speed of an object
distance is distance covered by an object
WORK it is done when we apply force to move a thing . example we push an almirah and it moves
DISPLACEMENT it is a vector tht points initial position to final positon .
ACCELERATION rate at which object increases or decreases it speed
VELOCITY it is the speed of an object
distance is distance covered by an object

Hello Friend !
The following concepts are explained below to satisfy your query:
Hope this may help you !
1) FORCE :
When you push or pull some object you exert a force on it. If you push a body you exert a force away from yourself; when you pull, you exert a force toward yourself. When you hold a heavy block in your hand you exert a large force; when you hold a light block, you exert a small force. The S.I. unit for measuring Force is called a Newton. Force is an interaction between two objects. It is a vector quantity.
2) WORK :
The quantity F.dr = Fdrcosθ is called the work done by the force F on the particle during the small displacement dr. A book falls off a table and free falls to the ground. This is an example of work. There is a force (gravity) which acts on the book which causes it to be displaced in a downward direction.
3) DISPLACEMENT :
Displacement is a vector quantity and can be defined by using distance concept. It can be defined as distance between the initial point and final point of an object.
4) VELOCITY :
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g.60 km/h to the north).
5) ACCELERATION :
Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. You change speed when you slow down. So if you slow down at a red light, you are accelerating (often called deceleration or negative acceleration). You change speed when you go faster. When you are merging onto a freeway and speed up to fit into the flow of traffic you are accelerating. You accelerate when you turn a corner or go around a curve even if you speed remains the same.
6) DISTANCE :
Distance is a scalar quantity representing the interval between two points. It is just the magnitude of the interval. If I walk 3 meters west, then turn and walk 4 meters north, you can easily calculate the distance traveled: 3 m + 4 m = 7 meters. Since this is a distance, there is no need to worry about the direction of travel.
Cheers !
