A Correct answer
Explanation

Galileo's law of inertia is another name for newton's First. law of motion
Newton's first law 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. Inertia comes from mass. Objects with more mass have more inertia

X and Y are two objects with masses $100\ kg$ and $75\ kg$ respectively, then :

  1. Both will have the same inertia

  2. Y will have more inertia

  3. X will have more inertia

  4. Both will have less inertia
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The object having more mass has more inertia and vice-versa.As object X has more mass than Y, thus X has more inertia.

Name the property of matter due to which a body continues in its state of rest or uniform motion unless an external force acts on it is:

  1. Inertia

  2. Elasticity

  3. Viscosity

  4. Density
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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

When the brakes are applied to bike the back seater moves forward why?

  1. Due to height

  2. Due to weight

  3. Due to inertia

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When the bike stops suddenly, the back seater will get a jerk in a forward direction due to inertia of motion as the bike is stopped the body in contact with the bike will also try to stop but the upper portion of the body will still try to maintain its motion.

Identify which of the following quantity describe object's resistance to change in motion.

  1. acceleration

  2. velocity

  3. mechanics

  4. force

  5. inertia
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

Mass of the object is the measure of inertia.
For higher mass objects, acceleration is lesser on application of some force, $a=\dfrac{F _{net}}{m}$

Which of the following best describe about the statement " An object slides on a horizontal, frictionless surface".

  1. Inertia

  2. Unbalanced forces

  3. Action and reaction force pairs

  4. Universal gravitation

  5. Simple harmonic motion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Law of inertia states that present state (in motion or stationary) of a body does not change until an external force is applied on it .

As the object  slides on a frictionless surface it means no external force is working on it ,so body will continue to slide due to inertia of motion.
