Answer 1

In a car moving in a straight line is covering same distances in same intervals of time it is called ……

1. Straight Motion
2. Uniform motion
3. Non Uniform Motion
4. Blaze Motion

Answer 2

Velocity is

2. Time / Speed
3. Speed / Time
4. Displacement / Time

Answer 4

What are the differences or similarities between Velocity and Speed?

1. Velocity doesn’t have direction and neither does speed
2. Velocity has direction and speed does not
3. Both Velocity and Speed has direction
4. Velocity has direction but speed doesn’t.

 

Select the correct statement

1. Average Velocity and Average Speed can be both positive and negative
2. Average Velocity cannot be both positive and negative
3. Average speed can be both positive and negative
4. Average Velocity can be both positive and negative while average speed is only positive

Answer – 4

 

Acceleration and velocity………………………….

1. Change values all of a sudden
2. Do not change values suddenly and the changes are steady
3. Acceleration changes values suddenly while Velocity does not
4. Velocity changes values suddenly while acceleration does not

In a velocity-time curve, if an object moves from time t1 to t2, then the area under the curve between times mentioned is equal to

1. Speed of the object
2. Velocity divided by time
3. Displacement of the object between time intervals t1 and t2
4. Speed divided by time
