By the end of this section, you will be able to establish the expression for centripetal acceleration and to explain the centrifuge.

By the end of this section, you will be able to calculate coefficient of friction on a car tire and to calculate ideal speed and angle of a car on a turn.

By the end of this section, you will be able to define arc length, rotation angle, radius of curvature, and angular velocity; and to calculate the angular velocity of a car wheel spin.

This lesson focuses on Newton's First Law: an object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means: a stationary object stays stationary; a moving object...

Manipulate variables while exploring principles and relationships related to moving in a circle at a constant speed. Students change the radius of the circle, the speed of the object, and the mass of the object and investigate the effect...

This app simulates circular movement and demonstrates how the position, speed, acceleration, and the applied force vary depending on the time. You may choose the option "slow animation" to make the movement ten times slower. You can also...

From a chapter on Rotational Motion and Angular Momentum in a Physics textbook. This section of the chapter discusses uniform and non-uniform circular motion, how to calculate angular acceleration, and the relationship between linear and...

By the end of this section, you will be able to describe uniform circular motion, explain nonuniform circular motion, calculate angular acceleration of an object, and observe the link between linear and angular acceleration.

[Free Registration/Login may be required to access all resource tools.] Using Newton's Law of Gravity and the equations of uniform circular motion, students solve problems involving the force of gravity.

This module is the introduction to model rotational motion. All of the concepts are conveniently recast into forms that have the same mathematical forms as their translational counterparts.
