WORK
Work is the change in position of an object due to the force, so that the object was said to do business when there forces acting on the locus and displacement. Enterprises can also say something that is done by the force on an object causes the object to move. Enterprises are also called as a result of displacement of the object times the force with the direction of the force. And if the direction of the force is opposite to the displacement of the object it is great business in a negative state.
Formulated mathematically in the following Enterprises:

Description:
W = Work (joules or Nm)
F = Force (N)
S = Distance moved (m)
Some examples of doing work activities are:
1. Pushing carts
2. Encouraging car
3. Attractive table
4. The time farmers plowing rice field
5. Rowing boat / canoe
Example:
1. The child pushing a cart with a force 30 N. The cart was moved as far as 20 meters, the work done How the boy?
completion:
F = 30 N
S = 20 m
W = ........?
Answer:
W = F x S
N = 30 N X 20 m
= 600 Nm
= 600 Joule
