A body is moving in such a way that magnitude of velocity does not change but the direction changes. Can we say that it is an accelerated motion? Give reasons for your answer
Answers
Answer:
Yes a body can definitely have acceleration if it is moving with constant speed. As speed is a scalar quantity, direction of movement doesn't affect it. But acceleration is a vector quantity as it is the rate of change of velocity, which is itself a vector quantity. So, take uniform circular motion as example.
PLEASE MARK BRAINLIEST....
PLEASE
Answer:-
i) Motion where Acceleration is observed is known as Accelerated motion.
ii) Since the velocity is constant, but the direction is changing and acceleration is a vector, especially direction in this case, in which change of velocity is observed. {Direction}
iii) So, it is in accelerated motion. Example was can prefer is "Merry-go-round".
Points to remember always:-
i) Acceleration is the rate of change of Velocity. Thus, it is also a vector quantity.
ii) Velocity is somehow like speed but, it is more informative. It specifies direction too.
