Motion
Assignment based on distance and displacement, uniform and nonuniform motion
1. What is meant by the term distance? What is the unit of distance?
2. Define the term displacement? What is the unit of displacement?
3. What are the characteristics of displacement?
4. What is meant by positive, negative and zero displacement?
5. Illustrate by drawing suitable diagram the distance travelled by a body and its displacement
6. When do the distance travelled and the displacement become equal?
7. How does the distance travelled by a body differ from its displacement?
8. A body is thrown vertically upwards rises up to a height of h, and returns to its initial position,
(a) Draw a figure describing the motion of the body,
{b) From the figure calculate,
i) the total distance travelled by the body.
(ii) the displacement of the body
9. Which of the following is true for displacement?
(a) it cannot be zero.
(b) its magnitude is greater than the distance travelled by the object.
(c) it can be zero.
10. An athlete completes one round of a circular track of diameter 200 m is 40 s. What will be the distance covered and the displacement at the end of 2 min and 20 s?
(Ans: displacement:200 m, Distance 2199 m)
11. Define (a) Uniform motion (b) Nonuniform motion.
