Question

what is uniform circular motion?​

Answer 1

Answer:

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. ... Nonetheless, it is accelerating due to its change in direction.

Answer 2

$\large{\underline{\underline{\frak{Uniform\: Circular\: Motion:-}}}}$

• When a body moves on circular track with constant speed, its direction changes as a result body posses acceleration which is always directed towards centre. So it is known as centripetal acceleration.

change in velocity

∆v = v2-v1

→ ∆v =∆s

→∆v/v=∆s/r [∆v = v/r∆s]

→ ∆v/∆t= v∆s/r∆t

→ a = vv/r

→ a = v²/r

→v = rw

→ a = (rw)²/r

→ a = rw²
