Two-Dimensional Motion

Front

What is rotational motion?

Back

Rotational motion refers to the motion of an object that rotates around a fixed axis.

Front

What is tangential acceleration?

Back

Tangential acceleration is the rate of change of velocity over time with a direction that is tangent to the curve.

Front

What is tangential speed?

Back

Tangential speed is the speed of an object that is tangent to the object's circular path.

Front

What is rotational kinetic energy?

Back

Rotational kinetic energy is the kinetic energy due to the rotation of an object and is part of its total kinetic energy.

Front

What is angular speed?

Back

Angular speed is the change of angle per unit time, measured in radians.

Front

What is the formula for tangential speed?

Back

Tangential speed (v) = radius (r) × angular speed (ω).

Front

What is the relationship between angular speed and linear speed?

Back

Linear speed is directly proportional to angular speed and the radius of the circular path.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, calculated as the product of force and the distance from the pivot point.

Front

What is moment of inertia?

Back

Moment of inertia is a measure of an object's resistance to changes in its rotational motion, depending on the mass distribution relative to the axis of rotation.
