Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?

Answer 1

An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.

Answer 2

Acceleration does not mean "speeding up". It means any change in speed or

direction. An object traveling in a circular path is constantly changing direction,

so there is acceleration there.

Answer 3

acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes.

This constant change in velocity causes the object to accelerate.

Answer 4

Because its direction is changing. Acceleration is a change in velocity, which has both a magnitude and a direction. In order to move in a circle, an object would have to exert (or be subject to) a continuous turning force.

Answer 5

Because "acceleration" is defined as any change in the speed or direction of motion,

and the direction of motion of an object moving in a circle is changing constantly.

Answer 6

def

" the rate of change of velocity is called acceleration"

example.

when we are driving ...after some time turn to enter in another street..

with the same speed....but the body have acceleration because there is change in velocity...as the velocity is vector quantity it depends on the magnitude as wall as

direction...while on turning there is change in velocity so there is an acceleration is the body with constant speed.............

Answer 7

This can often be slightly confusing and this is a simplistic explaination. An object is said to accelerate when either the velocity, direction or both changes. As an object in orbit is constantly changing direction if not speed then it is said to be accelerating. Sometimes confused with a vector which has the properties of both direction and speed.

Answer 8

Because it is constantly changing direction. It is not moving in a straight line.

Answer 9

Because its velocity is changing all the time. The speed is constant, the velocity is not.
