Physics - Circular Motion

Front

What is the definition of frequency in physics?

Back

Frequency is the number of occurrences of a repeating event per unit of time, measured in Hertz (Hz).

Front

How do you calculate the period of an oscillating object?

Back

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

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, keeping an object moving in that path.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v^2 / r, where v is the tangential speed and r is the radius of the circular path.

Front

What is tangential speed?

Back

Tangential speed is the linear speed of an object moving along a circular path, measured at any point along the path.

Front

What is the relationship between tangential speed and radius in circular motion?

Back

Tangential speed (v) is directly proportional to the radius (r) and the angular speed (ω): v = rω.

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

What is the direction of velocity in circular motion?

Back

The velocity in circular motion is always tangent to the circle at any point.

Front

What is the role of centripetal force in circular motion?

Back

Centripetal force is the net force acting on an object moving in a circular path, directed towards the center of the circle.

Front

What are the two variables that point towards the center of the circle in uniform circular motion?

Back

The centripetal force and the centripetal acceleration.
