# [Answer] An object moves in a circular path at a constant speed. Which is true?

###### Answer: The cars acceleration is not zero and causes the change in the direction of the cars velocity.
An object moves in a circular path at a constant speed. Which is true?

In physics circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform with constant angular rate of rotation and constant speed or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body.

Fri Dec 21 2001 13:30:00 GMT-0500 (Eastern Standard Time) · The object moves with constant angular velocity around the circle. Therefore θ = ω t {\displaystyle \theta =\omega t} where t {\displaystyle t} is time. Now find the velocity v {\displaystyle {\textbf {v}}} and acceleration a {\displaystyle {\textbf {a}}} of the motion by taking derivatives of position with respect to time.
