Question

Match the word with its definition. Column A1 . rotational speed 2 . tangential speed 3 . centripetal force 4 . centripetal acceleration 5 . Newton's Second Law 6 . Newton's First Law Column Ba. 1 revolutions per minute (RPM) b. instantaneous linear speed of an object in circular motion c. center-seeking change in direction of velocity d. an object in motion stays in motion unless an external force acts on it e. F = ma f. force that produces uniform circular motion

Answer 1

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.

Step-by-step explanation:

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 : 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.

Answer 2

Step-by-step explanation:

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.
