Newtonian Mechanics and Forces Questions

Multiple choice physics along with motion different types of motion basics of motion motion and reference point
The motion in which all points of a moving body move uniformly in the same line or direction is known as 

  1. Rolling

  2. Rotatory

  3. Both A and B

  4. Translational
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
If a body rotates its motion its rotatory. Rolling motion is combination of rotation and translation motion.
Only in translational motion body moves along a straight line, that means body doesn't rotate then its motion is translational.
Multiple choice particles of a gas ideal gases physics

Arrange in increasing order of greatest degree of freedom of motion:

  1. gas<solid

  2. Liquid< solid < gas

  3. Solid < liquid < gas

  4. Gas < liquid < solid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Solids have least degree of freedom. Liquids have more degree of freedom and gases have least degree of freedom.Degree of motion is proportional to the extent upto which a molecule can move freely.

Multiple choice geography amazing energy energy and uses energy and its different forms energy

 The energy which a body possesses by virtue of being in motion is called _______________.

  1. potential energy

  2. muscular energy

  3. mechanical energy

  4. kinetic energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The energy which a body possesses by virtue of being in motion is called Kinetic energy.
Kinetic energy is the type of energy, which a body possesses by the property of being in the motion. The potential energy is the type of energy, which a body possesses by virtue of its position is known as the potential energy.

Multiple choice physics kinematics motion around us motion and rest moving things around us

A ball lying on the ground does not move on its own because:

  1. it has inertia

  2. it has no energy

  3. it does not want to move

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to Newtons's first law , body remains in its state unless acted by external force. This property of body is termed as Inertia.

Option A is correct.

Multiple choice physics kinematics motion around us motion and rest moving things around us

When a body is at rest, it is obeying

  1. Principle of conservation of energy

  2. Principle of moments

  3. Newton's first law

  4. Newton's second law
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Inertia is the tendency of an object to remain at rest or in motion. Newton's First Law of Motion states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force.
So, when a body is at rest, it is obeying Newton's first law or motion or law of inertia.
