Given

  • A pair of bullocks exerts a force of 140N on a plough.
  • The field being ploughed is 15m long.

Required to Find

How much work is done in ploughing the length of the field ?

Solution

W = F × S

= 140 N × 15 m

= 2100N/m

= 2100J

Applied force

allied force is a force that is applied to an object by a person or another object

Gravitational force

When objects which have mass are attracted to eachother, the the force between them is known as gravitational force.

normal force

normal is the force that surface exert to prevent solid objects from passing through each other .

frictional force

friction is a resistance to motion of an object moving relative to another, it is not a fundamental force like gravity or electromagnetism .

air resistance force

a resistance is a force that is caused by the force acts in the opposite direction to an object moving through the air
