Rotational and Circular Motion. Rotational motion . refers to. ... as can be seen in the following examples. Example 8. Two children sit on a see-saw which is 3 m long and pivoted on an axis at its center. The first child has a mass m1 of 25 kg and sits at the left end of the see-saw, while the second child has a mass m2 of 50 kg and sits ...

The Kinematics and Dynamics of. ... Rotational motion is observed when an object itself rotates about some internal axis. Consider the following examples: A car traveling along a straight road exhibits linear motion from the perspective of a person standing on the side of the road. The wheels of the car exhibit rotational motion about the axle.

The study of rotational motion is continued in Chapter 10 where more general examples of rotational motion are considered. Rotational Kinematics: Angular Velocity and Angular Acceleration. Every point of a rigid object rotating about a fixed axis moves in a circle whose center is on the axis and whose radius is the radial distance from the axis ...

Examples of Centripetal Force: 1. What keeps the rubber stop spinning in a circle? ... Apple: Use simple kinematics, a – 9.8 m/s2. Moon: use rotational motion: a = v2/r . V is = x/t = 2(pi)r / (period) = 2(pi)r/T . Therefore, a = 4(pi)2 r / T2. Plug in the #’s, and you get .02272 m/s2. The moon had MUCH less acceleration than the apple. The ...

Chapter 10: Rotational Kinematics and Energy. Section . 10-1 Angular Position, Velocity and Acceleration. Position, displacement, distance, velocity, speed and acceleration can be used by an observer to describe the motion of an object. For rotational motion, there are analogous quantities: ...
