Define 1 Newton 1 joule and …

• According to Newton’s second law of motion, force acting on a body is the product of mass of the body and its acceleration.

F = m a

• The SI unit of force is kg ms−². It is represented by the symbol N.
• A force of one Newton produces an acceleration of 1 ms−² in a body of mass 1 kg.Newton = 1 kg × 1 m/s².

• One joule of work is said to be done on an object when a force of 1N displaces the object by 1 m along the line of action of force.
• When an electrical appliance consumes electrical energy at the rate of 1 joule per second, its power is said to be 1 watt.
