Chapter 7 Tangential Speed Section 1 Circular Motion Chapter 7 Tangential Speed The tangential speed (vt) of an object in circular motion is the object’s speed along an imaginary line drawn tangent to the circular path. Tangential speed depends on the distance from the object to the center of the circular path. When the tangential speed is constant, the motion is described as uniform circular motion.

Centripetal Acceleration Section 1 Circular Motion Chapter 7 Centripetal Acceleration

Centripetal Acceleration Section 1 Circular Motion Chapter 7 Centripetal Acceleration The acceleration of an object moving in a circular path and at constant speed due to a change in direction is called centripetal acceleration. Centripetal acceleration is always directed toward the center of a circle.
