Circular Motion

Front

What is circular motion?

Back

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

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

How does mass affect gravitational force?

Back

As mass increases, the gravitational force also increases, according to Newton's law of universal gravitation.

Front

What happens to velocity in circular motion?

Back

In circular motion, the velocity of an object is not constant because its direction changes continuously, even if its speed remains constant.

Front

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

Back

As the radius of the circular path decreases, the speed of the object also decreases, assuming constant centripetal force.

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 linear speed and r is the radius of the circular path.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed is the distance traveled per unit of time, while angular speed is the rate of rotation around a central point, measured in radians per second.

Front

What is the role of tension in circular motion?

Back

Tension in a string or rope provides the centripetal force needed to keep an object moving in a circular path.

Front

What happens to the gravitational force between two objects if the distance between them increases?

Back

The gravitational force decreases as the distance between the two objects increases, following the inverse square law.

Front

What is uniform circular motion?

Back

Uniform circular motion is when an object moves in a circular path at a constant speed.
