Questions Related to force and newton's laws

______ of the body is a measure of inertia. Fill in the blanks.

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. Mass

  2. Force

  3. Velocity

  4. Speed

Show answer
Correct Option: A
Explanation:

The object having the greatest mass has the greatest inertia. Thus mass is the measure of inertia.

Inertia depends on which two factors:

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. Height and Weight

  2. Length and Width

  3. Density and Mass

  4. Speed and Velocity

Show answer
Correct Option: C
Explanation:

Inertia depends on density and mass. Directly proportional to both of them.

Inertia is __________ .

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. a property of matter

  2. a type of force

  3. the speed of an object

  4. none of the above

Show answer
Correct Option: A
Explanation:

Inertia is a property of matter that offers the resistance to any change in its state of motion including changes to its speed and direction or the state of rest.

From the following 3 solids of the same shape and same volume which one has the highest inertia?

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. Steel

  2. Wood

  3. Aluminium

  4. None of the above

Show answer
Correct Option: A
Explanation:

Steel has highest mass and highest density which means it has highest inertia.

Fill in the blank: 

Tendency of an object to _____ a change in its state of rest or motion is called inertia

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. Allow

  2. Assist

  3. Resist

  4. None of these

Show answer
Correct Option: C
Explanation:

Due to inertia, objects resist any change in motion. 

Which law is referred to as the law of inertia?

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. First law of motion

  2. Second law of motion

  3. Third law of motion

  4. None of these

Show answer
Correct Option: A
Explanation:

Newton's first law of motion is referred to as the law of inertia

Inertia means resistance to the change of state.

physics force and newton's laws concept of inertia galileo's law and inertia mass and inertia

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Inertia is defined as the property by virtue of it, body tends to continue its state of rest or of uniform motion.

So, given statement is true.

Momentum is a measure of 

physics force and newton's laws momentum (p) introduction to momentum linear momentum

  1. Weight

  2. Mass

  3. Quantity of motion

  4. Velocity

Show answer
Correct Option: C
Explanation:

Momentum is mass* velocity.

For motion two questions are important, " How much is moving? " and "How fast is it moving?'
For change in state, inertia is necessary. Inertia is mass for translational motion. 
So, Quantity of motion is momentum.

A long-jumper runs before jumping to 

physics force and newton's laws momentum (p) introduction to momentum linear momentum

  1. Cover greater distance

  2. Maintain momentum conservation

  3. Gain energy by running

  4. Gain momentum

Show answer
Correct Option: D
Explanation:

While running a long distance, jumper tries to gain more velocity that increases his momentum. When he jumps, due this momentum, his body covers longer distance.

So, Option D is correct.
