Uniform Circular Motion

Motion

A body or an object needs to be moving

Circular

The path of the moving object is a circle

Uniform

The object is moving at a constant speed

Acceleration

The rate of change or velocity/time

Circumference

The distance around the circle

Angular Velocity (w)

• How fast the object is rotating

• How much angle it’s covering

• faster speed or smaller circle = faster rotation

Tangetial Velocity (Vt)

• The actual speed of the object moving along the edge of the circle

• Tangential because its direction is always tangent (touching) the edge of the circle

Tangential Acceleration (at)

• Occurs when the tangential speed is increasing or decreasing

Centripetal Force (Fc)

• The total force acting on the object where the direction is always towards the center of the rotation

Radius of Curvature (Rc)

• The radius of a circle at a particular point, it is the length of the curve
