Question

In a uniform circular motion, the direction of velocity at a certain point is:
(1 Point)

a)radially inward

b)radially outward

c)along the circumference

d)along the tangent​

Answer 1

Answer:

Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch. It is remarkable that points on these rotating objects are actually accelerating, although the rotation rate is a constant. To see this, we must analyze the motion in terms of vectors.
