A body is said to be in uniform motion when its (Velocity/ Displacement) remains constant.

Resistance to change in the state of motion is called _____ of motion.

A long jumper runs for a while before taking long jump so that the inertia of _____ helps him in taking a long jump.

Which of the following has more inertia—a rubber ball or a stone of same size? Why?

A ball is given some velocity at A and moves along a semi-circular ring fixed on a smooth horizontal table. The dotted line shows the path of the ball. In which direction $1, 2, 3$the ball will leave the ring.

Describe Galileo's experiment. What was the result of this experiment ?

Define Newton's first law and Inertia.

Give two examples each of Inertia of rest, Inertia of motion, and inertia of direction.

Two forces are applied on a block of mass $m=2 \mathrm{kg}$. How much force should be applied and in which direction to produce an acceleration of $1 \mathrm{m} {\mathrm{s}}^{-2}$. The surface is smooth.

(a) towards left?

(b) towards right?
