which best defines inertia
Answers
Answer:
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.
Inertia of Motion Examples
1. Seat belts tighten in a car when it stops quickly.
2. Men in space find it more difficult to stop moving because of a lack of gravity acting against them.
3.When playing football, a player is tackled, and his head hits the ground.
Examples of Inertia of Rest:
When a hanging carpet is beaten with a stick, the dust particles start coming out of it. When a carpet is beaten by stick the carpet is set into motion. But due to inertia, the dust particles remain at rest.
if any object is at rest it always want to be in rest and if any object is in motion it always want to be in motion, this phenomenon is called as inertia.
