# Centripetal Acceleration Questions

Centripetal acceleration is described as the characteristic of the motion in which an object moves in a circular path. Any object that transverses in a circular path with an acceleration vector directed towards the centre of that circle is called centripetal acceleration.

Acceleration can be measured in metres per second.

## Important Centripetal Acceleration Questions with Answers

1. Centripetal force is the force acting towards the _____ of the circular path.

1. Sides
2. Centre
3. Edges
4. None of the above

Explanation: The centripetal force is the force acting towards the centre of the circular path.

2. Centripetal force is given by the formula:

1. $$\begin{array}{l}F={mv^{2}}+{r}\end{array}$$
2. $$\begin{array}{l}F=\frac{mv}{r}\end{array}$$
3. $$\begin{array}{l}F=\frac{4}{mv^{2}}\end{array}$$
4. $$\begin{array}{l}F=\frac{mv^{2}}{r}\end{array}$$

$$\begin{array}{l}F=\frac{mv^{2}}{r}\end{array}$$

Explanation: Centripetal force formula is given by the formula

$$\begin{array}{l}F=\frac{mv^{2}}{r}\end{array}$$
.

3. Turning a car is an example of _______.

1. Oscillatory motion
2. Air resistance force
3. Linear motion
4. Centripetal force

Explanation: Turning a car is an example of centripetal force. Due to the friction between the road and tyres, the centripetal force causes the car to turn in a circular path.

4. Acceleration is the change in _____.

1. Distance
2. Displacement
3. Velocity
4. None of the above

Explanation: Acceleration is the change in velocity.

5. The unit of centripetal acceleration is ______.

1. m.s-2
2. m.s2
3. m.s
4. m-2.s

Explanation: The unit of centripetal acceleration is m.s-2.

6. The centripetal acceleration dimensional formula is ______.

1. M2L1T0
2. M0L1T-2
3. M2L2T0
4. M0L1T-1

Explanation: The centripetal acceleration dimensional formula is M0L1T-2.

7. Choose the right answer: The centripetal acceleration and the centripetal force have the same direction.

1. YES
2. NO

Explanation: Both centripetal acceleration and centripetal force possess the same direction.

8. State true or false: Gravitation is the main force for the planets to orbit around the Sun.

1. True
2. False

Explanation: Gravity is responsible for the motion of planets around the Sun.

9. Acceleration can be measured in _____.

1. Metres per second
2. Watts second
3. Metres
4. Joules per second

Explanation: Acceleration can be measured in metres per second.

10. Centripetal indicates towards the _____.
