Question

(a) time, (b) displacement, (c) speed, (d) velocity.
5. Which of the following are vector quantities?
(a) mass, (b) distance, (c) displacement, (d) work, (e) force, (f) acceleration.
6. An object is moving with constant velocity, find its acceleration.
7. Is it possible that the speed of a body changes while its velocity remains the same?
8 What is the displacement of a satellite when it makes a complete round along its circle
path?
9. A satellite goes round the earth in a circular orbit with constant speed. Is the motion
accelerated ?
U Can the distance travelled by an object be smaller than the magnitude of its displacement
1 A body is moving with uniform velocity. Is it necessary that it is moving along a straight line 1
2 What type of motion is represented by the tip of the 'second's hand' of a table clock? Is it
uniform or accelerated ?
3. Define uniform acceleration. What is the shape of the speed-time graph in such a case ?
4. Is it possible that a body is having zero velocity still is accelerating?
[Hint: A ball moving upward when reaches to its maximum height attains zero velocity
momentarily but has acceleration -gl.
5. A boy throws a ball vertically upward in a train moving with constant velocity. Will the ball
fall behind him, infront of him or into his hand ?
[Hint : Since boy and ball both are moving with speed of train in the direction of train se
ball will return into his hand.)
