Circular Motion

Front

What is Circular Motion?

Back

Circular motion is the motion of an object that revolves around a fixed point or axis in a circular path.

Front

What is the direction of acceleration in circular motion?

Back

In circular motion, the acceleration is directed towards the center of the circle, known as centripetal acceleration.

Front

What is the SI unit for circumference?

Back

The SI unit for circumference is meter.

Front

Define 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 formula for centripetal acceleration?

Back

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

Front

What is the relationship between velocity and centripetal force?

Back

Centripetal force is directly proportional to the square of the velocity of the object and inversely proportional to the radius of the circular path.

Front

What is the direction of velocity in circular motion?

Back

The direction of velocity in circular motion is tangent to the circular path at any point.

Front

What is the difference between rotation and revolution?

Back

Rotation refers to an object spinning around its own axis, while revolution refers to an object moving around another object.

Front

What is the formula for the circumference of a circle?

Back

Circumference (C) = 2πr, where r is the radius of the circle.

Front

What is angular velocity?

Back

Angular velocity is the rate of change of angular displacement and is measured in radians per second.
