Rotational Motion and Torque

Front

What is rotational motion?

Back

The circular motion of an object about an axis of rotation.

Front

What is circular motion?

Back

When an object moves in a circular path.

Front

What is spin?

Back

Rotation about an axis that goes through the center of mass of the object.

Front

What is angular displacement?

Back

The angular equivalence of distance, measured in radians.

Front

What is a revolution?

Back

One complete rotation, where every point on the circle returns to its original position, covering 2π radians (360 degrees).

Front

What is angular velocity?

Back

The rate at which the angle of rotation changes, measured in radians per second (rad/s).

Front

What is the relationship between tangential speed and angular speed?

Back

Tangential speed is given by the equation v = rω, indicating larger radius results in faster tangential speed for the same ω.

Front

What is angular acceleration?

Back

The rate of change of angular velocity, with units rad/s².

Front

What is the kinematics of rotational motion?

Back

Describes the relationships between the angle of rotation, angular velocity, angular acceleration, and time.

Front

What is torque?

Back

The rotational equivalent of force, calculated as τ = r × F × sin(θ).
