## 1. It is the property of a body by means of the body opposes itself its initial state of rest or motion is called ?

1. Motion
2. Inertia
3. Force
4. None of the above

Memory: No memory available.

## 2. Physical quantities which have magnitude only no direction is known as ?

1. Scalar quantity
2. Vector quantity
3. Fundamental quantity
4. None of the above

Memory: No memory available.

## 3. Shortest distance covered by a body in a definite direction is called ?

1. Displacement
2. Distance
3. Acceleration
4. Angular momentum

Memory: Distance is scalar quantity while displacement is vector quantity but both have the same unit which is meter.

## 4. Actual distance covered by a body in finite time is called ?

1. Velocity
2. Distance
3. Momentum
4. Speed

Memory: Distance is a scalar quantity.

## 5. It is the property of a body and formulate as mass multiplied by velocity is called ?

1. Angular velocity
2. Circular motion
3. Momentum
4. Retardation

Memory: If velocity is kept constant, larger the mass higher the momentum will be.

## 6. Meter/second2 is the SI unit of which of the following ?

1. Distance
2. Acceleration
3. Angular momentum
4. Angular velocity

Memory: Acceleration is defined by (Change in velocity/Time) and the unit of velocity is meter/second. Therefor, meter/second^2 is the unit of acceleration.

## 7. If a body returns to starting point after covering a certain distance, then average velocity will be ?

1. Zero
2. Infinite
3. Minimum
4. Maximum

Memory: As we know, when an object come back to starting point after covering a certain distance then displacement is zero. Therefore, as Velocity=Displace/Time and also Velocity= 0/Time = 0. Thus, average velocity will be zero.

## 8. Distance travelled by moving object in unit time interval is called ?

1. Inertia
2. Displacement
3. Speed
4. Velocity

Memory: Speed is defined by Distance/Time.

## 9. If velocity decreases with time then acceleration is ?

1. Positive
2. Negative
3. Maximum
4. Minimum

Memory: When velocity of an object decreses with time then acceleration becomes negative and it is also known as reterdation.

## 10. Displacement of an object in unit time interval is known as ?

1. Velocity
2. Acceleration
3. Momentum
4. Retardation
