RRB Junior Engineer / DMS / CMA 2019 · Question 3636 of 3719
Explanation: Mass: It is a unit to measure the amount of matter present in the body. It is expressed as m and its S.I and C.G.S unit are kilogram (kg). Acceleration due to gravity: The acceleration achieved by any object due to the gravitational force of attraction by any planet is called acceleration due to gravity by the earth. As each planet has a different mass and radius so the acceleration due to gravity will be different for a different planet. Weight: The weight(w) of an object is the force of gravity on the object and may be defined as the mass(m) times the acceleration of gravity(g). Weight is a force, the SI unit of weight isNewton. Weight (W) = m × g Where m is mass and g is the acceleration due to gravity.
