Can a body move on cuvred path without having acceleration?

Question

Can a body move on cuvred path without having acceleration?

Answer 1

No!

To understand this question, you've got to know the definition of acceleration, which can easily be defined as any change in direction or speed.

Ergo, by traveling on a curved path, you are accelerating, even if your speed isn't changing!

Answer 2

No

Answer 3

No. It should have acceleration non-zero in magnitude, which is not in the same line as velocity. In other words the angle between vector v and vector a should neither be 0 nor pi.

Answer 4

no, velocity involves direction, acceleration is the change in velocity.  Changing your direction of velocity means acceleration must be taking place.  Newtons first law!

Answer 5

Acceleration is any change in velocity over time. Velocity is a vector and has two parts to it, a magnitude and direction.

If the body stayed the same magnitude and direction, we have no acceleration. If it stayed in the same direction but increased or decreased in magnitude, then that is the acceleration we are familiar with when driving cars down the lane. But we can also keep the maginitude the same but change direction - the is also a type of acceleration. A body in orbit is this type of accelaration.

When a body goes along a curved path there always a portion of the curve that is in a different direction than the portion before. Thus, the body in a curved path always have some acceleration, becuse of the changing direction of velocity.

Hope that helps.

  

Answer 6

A body at rest tends to stay at rest. A body in motion tends to remain in motion in a straight line
