1. Rotational speed : It is defined as the number of revolutions per unit time i. e. revolution per minute.

2. Tangential speed : Instantaneous linear speed of an object in circular motion.

3. Centripetal force : This force acts on object when it moves in a circle. It is a force that produces uniform circular motion.

4. Centripetal acceleration : center-seeking change in direction of velocity

5. Newton's Second Law : This law defines the magnitude of force acting on the object. It is given by, F = m * a

6. Newton's First Law : An object in motion stays in motion unless an external force acts on it.

1. Rotational speed : ... revolutions per minute

2. Tangential speed : Instantaneous linear speed of an object in circular motion.

3. Centripetal force : ... force that produces uniform circular motion

4. Centripetal acceleration : center-seeking change in direction of velocity

5. Newton's Second Law : F = ma

6. Newton's First Law : An object in motion stays in motion unless an external force acts on it.
