Question

A car covers a distance of 10 m in 10 s and next 10 m in next 10s.Then its
1. Speed is constant but velocity may or may not be constant.
2. Velocity is constant but speed may or may not be constant.
3. Speed and velocitt both may be varying.
4. Both 1 and 2
Choose the correct and give the explanation.

Answer 1

Answer:

answer is 1 speed is constant and velocity not

Explanation:

because

speed is simply how fast you traveling

but

velocity is 'speed in given direction'

so

the car covering same distance in same time so the speed is constant and velocity not

Answer 2

The correct answer is option (1) Speed is constant but the velocity may or may not be constant.

• It is given that the distance traveled by car is 10 m in 10 s and the next 10 m in the next 10 s. So it is clear that the speed is constant as speed is a scalar quantity. It does not depend on the direction in which the car is moving.

• Now, velocity is a vector quantity. The question the car could have traveled the next 10 m in opposite direction but at the same time. So, in that case, the velocity will not be constant.
