Inertia
How easy is it for your body to keep moving and bump into your friend when the school bus stops suddenly? That’s inertia.
Inertia is the tendency of an object to resist changes in its motion.
If something is resting, it stays at rest. If something moves, it keeps moving with the same speed and in the same direction until a force acts on it.
This idea is a part of Newton’s First Law of Motion, also called the Law of Inertia.
The more mass an object has, the greater its inertia. So, heavier objects are harder to start or stop moving than lighter ones.
Think about when your parents remind you to wear a seatbelt for safety in a car.
That’s because when the driver suddenly brakes, your body keeps moving forward even though the car has stopped. Seatbelts protect you by keeping you in place.
Similarly, consider a book resting on a table. It won’t move unless a force acts on it. Inertia is all around us, keeping objects either in motion or at rest.
