FLASHCARD QUESTION

Front

What is Circular Motion?

Back

Circular motion is the motion of an object that moves along a circular path. It can be uniform (constant speed) or non-uniform (changing speed).

2.

FLASHCARD QUESTION

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.

3.

FLASHCARD QUESTION

Front

What is Centripetal Acceleration?

Back

Centripetal acceleration is the acceleration that occurs in circular motion, directed towards the center of the circle, and is responsible for changing the direction of the object's velocity.

4.

FLASHCARD QUESTION

Front

What is the formula for Centripetal Acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v²/r, where v is the linear speed and r is the radius of the circular path.

FLASHCARD QUESTION

Front

What happens to the net force at the top of a vertical loop?

Back

At the top of a vertical loop, the net force acts downwards towards the ground, combining gravitational force and centripetal force.

6.

FLASHCARD QUESTION

Front

How does speed affect centripetal force?

Back

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

7.

FLASHCARD QUESTION

Front

What is the relationship between velocity and acceleration in circular motion?

Back

In circular motion, velocity is tangent to the circular path, while acceleration (centripetal acceleration) points towards the center of the circle.
