When an object is in uniform circular motion, the acceleration of the object toward the center axis is known as acceleration.

A disc accelerates uniformly from 300 revolutions per minute to 600 revolutions per minute in 25 (s). What is the linear acceleration of a point on the rim of the disc, if the radius of the disc is 250 mm.

A ball travels in uniform circular motion with a Period of 2 seconds. What is the tangential velocity of the object if it is moving in a circle of radius 2 m? 2π m/s m/s 4π m/s 2 m/s 4 m/s

At some instant, a particle is traveling in a horizontal circular path of radius 6.6m, has a total acceleration with a magnitude of 19m/s^2 and a constant tangential acceleration of 12m/s^2. Determine the speed of the particle at this instant 1/8 of a revolution later.

How fast (in rpm) must a centrifuge rotate if a particle 7.5 cm from the axis of rotation is to experience an acceleration of 2.0×105 g's? Express your answer using two significant figures.

Question 02: An object moving on a plane circular path with a constant speed has an outward radial acceleration. zero acceleration. an inward radial acceleration. a tangential acceleration. a constant velocity.

When an object is in uniform circular motion, the velocity of the object never changes. True False

Draw a vector diagram that shows the tangential velocity and the centripetal acceleration of the object traveling in a circle.
