What is a inertia in science?
inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.
What is mean by inertia example?
Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.
What is inertia of a body?
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 does inertia mean in science term?
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’s the best definition of inertia?
Definition of inertia. 1a : a property of matter by which it remains at rest or in uniform motion in the same straight line unless acted upon by some external force. b : an analogous property of other physical quantities (such as electricity) 2 : indisposition to motion, exertion, or change : inertness.
What is a simple example and meaning of inertia?
Inertia is the resistance of the object to any change in its motion , including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force . For example, a rubber ball will not start bouncing around unless someone picks it up and throws it.
How can inertia be defined?
Inertia is defined as the force which keeps stationary objects to stay still (remain at rest) or moving objects in motion at the same speed and in the same direction unless it is stopped by an external force. It can also be defined as the resistance of an object to resist change by remaining in its state of rest or in motion .
