hey Clara are u going to uninstall brainly!!! pls answer in my question pls!!!.....
1.distinguish between speed and velocity....
2.when will you say a body is in (i) uniformacceleration
(ii) non-uniform acceleration
no spam!!!
Answers
Answer:
(1) Uniform acceleration- If a body travel in a straight line and its velocity increase and decrease at Equal interval of time.
(2)- Non- Uniform acceleration- When the body moving in an non straight path with different rate of velocity at different interval of time.
Hope it will help you buddy
Speed :
1. (i) Speed is defined as the distance travelled by the body per unit time
(ii) Speed = distance travelled/ time taken
(iii) Speed is a scalar quantity
(iv) Speed is always positive
Velocity :
(i) Velocity of a moving body is defined as is rate of change of its position with time in a particular direction
(ii) Velocity = displacement / time taken
(iii) Velocity is a vector quantity
(iv) Velocity can be negative
2. (1)When a body is changing its velocity at a constant rate, then the body is said to be moving with uniform acceleration.
(2)When a body is changing its velocity at different rates, then the body is said to be moving with non-uniform acceleration.
hope this helps you.
pls mark as brainliest.
