(a) Distinguish between mass and weight of an object. (b) How will the weight of a body of mass 100g change if it is taken from equator to the poles? Give reason for your answer.

(a)

Mass

Weight

1. The quantity of matter contained in a body is called mass of the body.

1. The force with which the earth attracts a body towards its centre is called the weight.

2. Mass is a scalar quantity.

2. Weight is a vector quantity.

(b) W = mg

As 'g' is greater at the poles than at the equator, the weight of the body increases from equator to poles.

CBSE 9 - Physics
A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
