Centripetal Motion Flashcard Retake

Front

What is centripetal motion?

Back

Centripetal motion refers to the motion of an object moving in a circular path, where it is constantly changing direction due to the presence of a net inward force acting towards the center of the circle.

Front

What is the formula for centripetal acceleration?

Back

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

Front

What is the relationship between period (T) and frequency (f)?

Back

The period (T) is the time taken for one complete cycle of motion, while frequency (f) is the number of cycles per unit time. They are related by the equation: f = 1/T.

Front

What is angular velocity?

Back

Angular velocity (ω) is the rate of change of angular displacement and is measured in radians per second (rad/s). It can be calculated using the formula: ω = 2πf.

Front

What is a clothoid loop?

Back

A clothoid loop is a type of roller coaster loop that gradually changes radius, providing a smoother transition for riders compared to a circular loop.

Front

How does the direction of velocity change in circular motion?

Back

In circular motion, the direction of velocity is always tangent to the circle at any point, meaning it continuously changes direction while maintaining constant speed.

Front

What is the significance of the net force in centripetal motion?

Back

The net force in centripetal motion is directed towards the center of the circular path and is responsible for changing the direction of the object's velocity, allowing it to maintain circular motion.

Front

What is the formula for calculating angular frequency?

Back

Angular frequency (ω) can be calculated using the formula: ω = 2πf, where f is the frequency of the motion.

Front

What is tangential velocity?

Back

Tangential velocity is the linear speed of an object moving along the circular path and is directed tangent to the circle at any point.

Front

What is the role of gravity in vertical circular motion?

Back

In vertical circular motion, gravity acts as a force that affects the speed and tension in the string or track, influencing the motion of the object.
