Accelerated Circular Motion (04:26)
Review uniform circular motion and learn about tangential acceleration. View the total acceleration equation. A sample problem determines tangential acceleration.
Accelerated Circular Motion Review (00:52)
Accelerated motion in a circle occurs when an object's velocity changes its magnitude. Hear tangential acceleration properties.
Rotational Motion (07:15)
Rotating objects are described by theta, the angle through which they rotate. Learn how to find a radian measurement of a circle, convert degrees to radians, determine angular velocity, and find the linear speed of a point on a globe.
Rotational Motion Review (00:50)
An object rotates about an axis at the theta angle, measured in radians. Review equations for angular velocity and linear speed.
Linear Momentum (01:57)
Learn about the vector quantity of linear momentum. View a sample problem determining the momentum of a basketball player.
Principle of Conservation of Linear Momentum (07:13)
When two particles collide, the final momentum of the system equals the initial momentum of the system. Determine a basketball player's velocity after colliding with another player.
Linear Momentum Review (00:28)
Newton derived the Laws of Motion from the Principle of Conservation of Linear Momentum, where the sum of total momenta equals zero and the total momentum after a collision equals the total momentum before it.
