Uniform circular motion is characterized by an object moving round the circumference of a circle at a constant speed.

However, the direction of the velocity is constantly changing.

Also, centripetal acceleration is always towards the center, so direction changes constantly.

Centripetal acceleration has the same direction as the net force in UCM.

In uniform circular motion, which of the following are constant:

Check all that apply.

a) the speed is constant

b) the magnitude of the velocity is constant

c) the direction of the velocity is constant

d) the magnitude of the angular velocity is constant

e) the magnitude of the centripetal acceleration is constant

f) the magnitude of the net force is constant

g) the direction of the angular velocity is constant

h) the direction of the centripetal acceleration is constant

i) the direction of the net force is constant
