always directed vertically downwards.
Answers
21.W = m ∗ g W = m * g W=m∗gComparing Mass and Weight
Mass is a property of matter. The mass of an object is the same everywhere. Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity.
Mass may be measured using an ordinary balance. Weight is measured using a spring balance.
22.Motion | Short/Long Answer Questions
Solution: The mass of a body is constant and it does not change by changing the position of the body.
23.Mass is the quantity of matter contained in a body. Weight is the force with which the earth attracts the body. Weight is always directed vertically downwards.
