Circular Motion

Front

What is the SI unit for circumference?

Back

meter

Front

Centripetal acceleration always points:

Back

towards the center of the circle

Front

What is the direction of the acceleration at point A, if the ball is revolving clockwise?

Back

down

Front

What is the process or act of turning or circling around something?

Back

Rotation

Front

Which statement is true about an object that is traveling in uniform circular motion?

Back

The net force on the object is directed toward the center of the circular path.

Front

Define circular motion.

Back

Motion of an object in a circular path.

Front

What is centripetal force?

Back

The net force that acts on an object moving in a circular path, directed towards the center.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is the linear speed and r is the radius.

Front

What is the relationship between linear speed and angular speed in circular motion?

Back

v = r * ω, where v is linear speed, r is radius, and ω is angular speed.

Front

What is the difference between uniform and non-uniform circular motion?

Back

Uniform circular motion has constant speed; non-uniform has changing speed.
