1. Encircle the correct option. The motion of blades of electric fan is an example of (a) Translatory motion (b) Vibratory Motion (c) Linear motion (d) Rotatory motion The shortest distance from initial point to final point is known as (a) position (b) distance (c) displacement (d) speed If a body covers equal distance in equal intervals of time, however small the intervals may be, the speed of body is said to be (a) uniform (b) variable (c) average (d) none of these When two bodies are in motion then the velocity of one body relative of the other is said (a) average velocity (b) acceleration (c) relative velocity (d) variable velocity The rate of change of velocity of body is known as (a) acceleration (b) average velocity (c) displacement (d) total distance coverd Two balls of different masses are dropped freely from a tower which ball will reach the ground first (a) light ball (b) heavy ball (c) both balls will reach at the same time (d) heavy ball reach the ground first The speed of a car increases from 20〖ms〗^(-1) to 50〖ms〗^(-1) in 10 seconds. Its acceleration is (a) 2〖ms〗^(-2) (b) 3〖ms〗^(-2) (c) 5〖ms〗^(-2) (d) 7〖ms〗^(-2) The periodic motion of the pendulum of a clock is an example of (a) rotatory motion (b) translatory motion (c) vibratory motion (d) linear motion A ball was dropped from a tower freely. The distance covered in first second is (a) 5m (b) 10m (c) 50m (d) 100m A cyclist starting from rest moves with an acceleration of 2〖ms〗^(-2). What distance it will cover in 10 seconds?
