Question

plz help me give answers in half hour.​

Answer 1

• uniform velocity
• in uniform motion
• moving with uniform acceleration

Answer 2

Answer:

1. b

Explanation:

If the displacement of an object is proportional to the square of the time taken then the body is moving with uniformly accelerated motion as it will follow Newton's second equation of motion for a particular initial velocity, which can be given by, s=ut+21at2

2. c

Explanation:

In the given graph we find that the velocity is constant throughout, hence the object represented in the v-t graph is said to be in uniform motion. Zero acceleration is also uniform acceleration.

3. d

Explanation:

Given boy is enjoying a ride on merry go round which is moving with constant speed of 10m/s. So, when the boy moves in a circular path ( merry go round) with uniform speed it's motion is uniform circular motion. In uniform circular motion, speed remains contant, but the direction of motion is constantly changing.
