Define work in physics?
Work is said to be done by a force if the point of application of the force gets displaced. Work is measured by the product of the force and the displacement component in the direction of the force. Hence W = F s cos @ @ is the angle between the force vector and displacement vector.
What are the quantities on which the amount of work done depends and How are they related to work?
work depends on:FORCE and DISPLACEMENT. it is directly proportional to both of them. work can be calculated by the product of force and displacement. if displacement is in a certain direction to the applied force then work done is calculated by force*displacement cos(angle). work done becomes 0when:- *displacement is 0 or the initial point and final point are the same. *displacement is in perpendicular direction to force applied.
When a force is applied on a moving bodyits motion is retardedThen the work done is?
By Definition of force work = force X displacement since the force depends upon the displacement which can either +ve, -ve or zero so if any object is retarding mean there can be many possibilities 1. if the force is applied opposite to the direction of object then the work done is negative. 2. if the force is on same direction then the work done is positive. in both the cases the displacement will be positive THIS KIND OF FORCE IS CALLED RETARDED FORCE
What conditions must be met for work to be done?
1. A force is needed 2. The point of application of the force is to be displaced. 3. If the displacement is in the direction of the force then work is said to be done by the force and if the direction of displacement is opposite to the force then work is done against the force.
What work is being done when pulling?
It is the pulling force applied multiplied by the displacement of the object being pulled in the direction of the pulling force.
What force allows work to be done?
Any force can produce work if it causes displacement. If displacement is in opposite direction of force, work done will be negative and if displacement is in direction of force work done will be positive. If there is no displacement, work done is zero. Eg: Gravitational force pulls you down towards earth, in pulling you down it does work on you which gets stored in form of potential energy. Energy for A+

Write the formula for the work done on a body when a force acts on the body in the direction of its displacement?
WORK = FORCE x DISPLACEMENT

What is the scalar product of the force action on an object and the displacement caused by that force?
Work is the scalar product of the force acting on an object and the displacement caused by that force. In order for work to be done, the object must be moved in the direction of the force.

What work is being done when pulling?
It is the pulling force applied multiplied by the displacement of the object being pulled in the direction of the pulling force.
What are two factors do you need to know to calculate how much work has done in any situations?
The displacement produced by the body. The amount of force subjected to the body. The angle between the direction of force and displacement.
In the term of physics is work said to be done when we walk?
If you start walking on the flat ground, then the displacement is caused at right angles to the direction of your movement. In a way, the displacement does not take place in the direction of force applied by your shoulder. Hence, no work is done.
Why work done is not a function of time?
Work is the scalar product of Force acting and displacement produced in the direction of the force. So it is independent of time.
What is defined work?
if the force applied on a body makes a body move that is there is a displacement of the point of application of force in the direction of force then work is said to be done by the body
