... • There is always centripetal acceleration no matter whether the circular motion is uniform or nonuniform. • It is the tangential acceleration that is zero in uniform circular motion. Example 7.4: A wheel is rotating wit a constant angular acceleration of 3.5 rad/s2. If the initial angular velocity ...

... Newton’s 3rd Law of Motion: if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. Ex. a skater pushes on another; both move but the skater who pushed is pushed back with an equal but opposite force. ...
