what is the work done if we apply a 1.2N force and we move 4 m in the direction of force
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
If you apply a force to the outward or inward direction on a door or a window it will move to the direction of the applied force. If you apply the force towards the direction of the hinge then the door will not move. If you are superman then it will break. If you apply the force to opposite sides of a can then the can gets pressed. There are countless examples which are impossible to mention unless you can be specific in your approach to your imagination.
Newton's 1st law of motion: an object will continue on its course at the same speed and direction, if the net force acting on the object is zero. Hence, if you don't apply any net force on the object, its direction and speed will not change (it will not move on a curved path). If you want the object to change direction, you need to apply a net force away from the direction of travel (the net force is pointing at a non-zero angle with the direction of travel).
A person pushing a box across a floor:· Mass of box = 20 KG, Weight of Box = 196.2· Distance moved in the direction of the force = 2m· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules

The load will move upwards.
Yes, if you push the book in the opposite direction with enough force, the book will move in that direction. The book's motion is determined by the force you apply to it.
There are 3 conditions for work. First, there must be force. Second, when you apply a certain amount force to an object, it must move a certain distance. lastly, the force that you applied and the direction of the motion must be parallel. If you applied force tot eh right, then the object must move to the right. When you lift a book and then you walk around, no work is done. The direction of the force of your hand is going upwards while the direction of your motion is either left or right. Therefore the force applied and the distance moved are perpendicular.
Work is the product of a force and the distance through which it acts in the direction of the force. In order for work to be done, the object must move in the direction of the force. If you push on a brick wall until you exhaust yourself and the wall doesn't move, you have not done any work. If you push on a box and it moves in the direction that you are pushing it, you have done 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
A person pushing a box across a floor:· Mass of box = 20 KG, Weight of Box = 196.2· Distance moved in the direction of the force = 2m· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules
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.
Force applied times the distance traveled is work or energy. Think about it...You apply a force to an object, say: push a crate, and you move it a distance. What has been done?? Work. Work is equivalent to energy and is measured in Newton-meters (Nm) or Joules (J).
