Question # 1

What is different between

Ans 1: Mass and Weight ,Action and Reaction, Sliding and Rolling Friction
Ans 2: Mass of a body is the quantity of matter possessed by the body
It is a scalar quantity
It is measured by using a common balance
It remains same every where
The SI unit of mass is kilogram (kg)
It is a base quantity.
Ans 3: WEIGHT: Weight of a body is the force of gravity action on it
It is a vector quantity
It varies depending upon acceleration dua to gravity
The SI unit of weight is newton (N)
It is a derived quantitiy
Ans 4: Action and Reaction: The force exerted by external agency on a system is caused action.
REACTION: Response of the system to the force exerted by external agency is caused reaction.
Ans 5: SLIDING FRICTION: In sliding friction the surface of a body moves by sliding against the surface of another body
ROLLING FRICTION: Rolling friction is the force of friction between rolling body and a surface over which is rolls
