M6 L2 Notes Review (Physics)

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.

Front

In uniform circular motion, what direction does the acceleration point?

Back

The acceleration points inward, toward the center of the circle.

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed toward the center of the circle.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a) = v²/r, where v is the linear velocity and r is the radius of the circular path.

Front

What is the relationship between period and frequency in circular motion?

Back

Frequency (f) is the reciprocal of the period (T): f = 1/T.

Front

What is centrifugal force?

Back

Centrifugal force is a fictitious force that appears to act outward on a mass moving in a circular path, perceived in a rotating reference frame.

Front

How does centripetal acceleration change with speed?

Back

Centripetal acceleration increases with the square of the speed; if speed doubles, centripetal acceleration increases by a factor of four.

Front

What happens to centripetal force if the radius of the circle increases?

Back

If the radius increases while maintaining the same speed, the centripetal force decreases.

Front

What is the effect of mass on centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; as mass increases, centripetal force increases.

Front

What is the significance of the radius in circular motion?

Back

The radius determines the curvature of the path and affects both the centripetal acceleration and the required centripetal force.
