Conceptual Questions

Question 1 An object has moved through a distance. Can it have zero displacement? If yes, then support your answer with an example.

Answer 1

Yes, an object that has moved through a distance can have zero displacement.
Example: Person walking along with a circular moving along a circular path, starts at point A and returns back to point A then total distance covered would be $2pi r$ but the net displacement of the object would be zero.

Question 2 Under what conditions are the magnitude of the average velocity of an object equal to its average speed?

Answer 2

The magnitude of the average velocity of an object is equal to its average speed when the velocity of an object changes at a uniform rate, i.e., the body is in uniformly accelerated motion.

Question 3 Can the magnitude of displacement be more than distance.

Answer 3

No, magnitude displacement can be equal to distance but it can not be more than distance.

Question 4 What is the displacement of motion of the tip of the minute hand of a clock in one hour?

Answer 4


Question 5 Is it possible to have non-zero velocity for a time interval, while the acceleration is zero at any instant within the time interval?

Answer 5

$$acceleration=frac{text{change in velocity}}{text{time taken}}$$
This shows that acceleration is zero when the change in velocity (v-u) is zero or we can say when a body is moving with uniform velocity, it’s acceleration will be zero. For example, if a car is moving with a constant velocity of 15m/s, then its acceleration is zero.
So it is possible to have non zero velocity for a time interval, while the acceleration is zero at any instant within the time interval.

Question 6 What is the nature of distance-time graphs for uniform and non-uniform motion of an object?

Answer 6

For uniform motion graph, it would be a straight line and for non-uniform motion, it would be a parabola

Question 7 What do you think about the speed-time graph given below

Answer 7

Speed being a scalar quantity can not have a negative value.

Question 8 What does the area between the v-t graph give?

Answer 8

The area v-t graphs give the displacement of the object.

Question 9 Is uniform circular motion an example of constant acceleration?

Answer 9


Question 10 An artificial satellite goes around the earth in a perfectly circular orbit with constant speed. Is the motion accelerated? Why?

Answer 10

Yes, as the direction of velocity is changing to keep the satellite in a circular orbit.
