Answer: inertia. noun. Physics The tendency of a body at rest to remain at rest or of a body in straight line motion to stay in motion in a straight line unless acted on by an outside force; the resistance of a body to changes in momentum.
What is inertia in simple words?
Inertia is the tendency of an object to continue in the state of rest or of uniform motion. The object resists any change in its state of motion or rest. … This is because of inertia.
How do you explain inertia to a child?
Inertia is the tendency of a body to resist a change in motion or rest. When a vehicle stops, you tend to jerk forward before coming to a complete stop. In the same way, you will jerk backwards when the vehicle begins to move.
What are 5 examples of inertia?

What is inertia in a car?
INERTIA. Inertia is the resistance to change the direction or velocity of a body, either at rest or in motion. In this case, it is related to changing the heading, or direction, of a vehicle; that is, changing from straight ahead driving to a turn.
What is inertia of motion give one example?
Examples of Inertia of Motion: 1) The passengers fall forward when a fast moving bus stops suddenly: When the driver of a bus applies brake suddenly, the lower part of the body comes to rest as the bus comes to rest but, the upper part of the body continues to move forward due to inertia of motion.
Which best defines inertia?
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
What are the 3 types of inertia?
There are three forms of inertia: 1. Resting inertia 2. Motion inertia 3. Directional inertia.
Is inertia good or bad?
The answer: Inertia is an explanation of facts. It’s not “good” or “bad” because it’s neutral. It’s simply an observation and a statement of fact.
What is body inertia?
The tendency of a body to resist any change in its motion (speed or direction) – in other words, to resist any change in its acceleration – is called its ‘inertia’. Mass can be thought of as a measure of a body’s inertia. Inertia means ‘reluctance to change’.
What are the 4 types of inertia?
What are different types of inertia and examples?
- Inertia of Rest.
- Inertia of Direction.
- Inertia of Motion.
What is inertia give an example class 9?
The inertia of Motion: The inability of the body to change by itself its state of motion is called inertia of motion. Example: A person sitting in a cars falls forward when the car applies break. As the lower portion of the car comes to rest and upper part remains in motion because of inertia of motion. 3.
What is inertia in 9th class?
Inertia: Inertia can be defined as the characteristic of an object which resists changes to the state of the motion of the object.
What is inertia and its types with examples?
Inertia of rest: The tendency of a body to remain in its position of rest is called inertia of rest. Example: While standing in a bus, we fall backward if the bus starts suddenly. Inertia of motion: The tendency of a body to remain in its state of uniform motion in a straight line is called inertia of motion.
How do we use inertia in everyday life?
10 examples of law on inertia in our daily life
- You tend to move forward when a sudden break is applied.
- You feel a backward force when the bus moves quickly from rest.
- Dusting bed with a broom removes dust due to inertia of rest.
- when you shake a branch the leaves get detached.
- Experiencing jerk when lift suddenly starts.
What is inertia at rest?
The inertia of rest is the tendency of a body to resist a change of state of motion from rest by an external force. This tendency of objects can be derived from Newton’s first law which states that an object in rest continues to be in rest unless acted upon by an external force.
Is inertia a force?
Inertia is a force. Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. … A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects.
What is Newton’s third law?
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. … If a body has a net force acting on it, it undergoes accelerated motion in accordance with the second law.
Is inertia the same as Newton’s first law?
law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
How do you use inertia in a sentence in science?
(physics) the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force.
- I’m unable to throw off this feeling of inertia.
- We had a feeling of inertia in the afternoon.
- She lapsed into inertia and lay there as if asleep.
- Inertia carried the plane onto the ground.
What is inertia of motion with 2 example?
Examples of Inertia of Motion: 1) The passengers fall forward when a fast moving bus stops suddenly: When the driver of a bus applies brake suddenly, the lower part of the body comes to rest as the bus comes to rest but, the upper part of the body continues to move forward due to inertia of motion.
