Rotational Motion Physics, Basic Introduction, Angular Velocity & Tangential Acceleration

This physics video tutorial provides a basic introduction into rotational motion. It describes the difference between linear motion or translational motion and rotational motion. It provides the formulas and equations for angular velocity given angular displacement, linear velocity given distance and time, frequency, period, tangential acceleration, angular acceleration, and centripetal acceleration.

3:51 since arch length (s) is a scalar quantity that represents the distance the rotating objects makes from the initial position to the final position, so (s/t) represent its speed, not velocity; consequently, (w*r) is the speed, not the velocity of the object, am I correct?

what does centripetal acceleration do to the motion of the object? does the centripetal acceleration mean the object accelerates toward the center based on the arrow?

[@jamesmacrae7730]

A centripetal acceleration is what keeps the body in circular motion, and this centripetal acceleration is enforced by a centripetal force. This centripetal force could be the gravitational force acting on a satellite by a planet.

A 50 kg skip attached to a steel rope on a crane is used to hoist bricks from the ground to the top of a construction site. The steel rope is wound onto a lifting drum with a diameter of 700 mm and rotational frequency of 49 revolutions per minute. The lifting drum is situated on the top floor which is 154 m high. How many seconds will it take to lift bricks, three quarters up the height of the building?

That doesn't really explain tangential acceleration though, not clearly at any rate. Ac is for uniform angular velocity, so if your circular motion is acceleration, at what point are you measuring Ac in order to calculate a_net?
