Circular Motion and Gravitation Flashcardizz

Front

What is the definition of frequency in circular motion?

Back

Frequency is the number of rotations that occur in 1 second.

Front

What force keeps an object moving in a circular path?

Back

Tension is the force that keeps the ball from flying off on a tangent when swung in a circle.

Front

What is the definition of period in circular motion?

Back

The period is the amount of time it takes for one complete rotation.

Front

How does increasing rotational speed affect apparent weight in a rotating habitat?

Back

The apparent weight of people inside increases as the rotational speed of the habitat increases.

Front

How do you calculate linear speed on a Ferris wheel?

Back

Linear speed can be calculated using the formula: Linear Speed = Circumference / Time for one rotation.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius 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 towards the center of the circle.

Front

What is the relationship between linear speed and angular speed?

Back

Linear speed (v) is related to angular speed (ω) by the formula: v = rω, where r is the radius.

Front

What happens to the centripetal force if the speed of an object in circular motion increases?

Back

If the speed increases, the centripetal force must also increase to maintain circular motion.

Front

What is the role of gravity in circular motion?

Back

Gravity can act as a centripetal force in cases like planets orbiting the sun.
