Question #265b4

Aug 20, 2017

In uniform linear motion (going in a straight line), velocity is constant or changing (accelerating). Circular motion (going in a circle) has a constant acceleration. (but can have constant speed)

Explanation:

Velocity = $\frac{\Delta d}{\Delta t}$
So since an object going in a circle is constantly changing its direction, it's changing d $\therefore$ changing velocity.

And acceleration = $\frac{\Delta v}{\Delta t}$ so if velocity is constantly changing, then the object is accelerating.
