Question

The acceleration of an object that is moving with uniform circular motion is (Check any and all that apply):

a) Always perpendicular to the direction of motion of the object
b) Always in a direction pointing to the center of the circle
c) Constant in magnitude
d) Always in the direction of motion of the object

Answer 1

The correct options are: a) Always perpendicular to the direction of motion of the object and b) Always in a direction pointing to the center of the circle. In uniform circular motion, the object moves in a circular path at a constant speed.

Step-by-step explanation:

The correct options are: a) Always perpendicular to the direction of motion of the object and b) Always in a direction pointing to the center of the circle. In uniform circular motion, the object moves in a circular path at a constant speed. The acceleration of an object undergoing uniform circular motion is always directed toward the center of the circle and is perpendicular to the object's instantaneous velocity. This acceleration is called centripetal acceleration, and it is responsible for changing the direction of the object's velocity but not its speed. So, options a) and b) are correct for the acceleration in uniform circular motion.
