Acceleration explained in an easy to understand way.
Acceleration
A change in velocity with respect to time. Acceleration. Acceleration is how quickly something speeds up, slows down, or changes direction.
Inertia explained in an easy to understand way.
Inertia
The tendency of objects to resist any change in motion. Inertia. Inertia means that objects will keep doing what they're doing, like staying still or moving, unless something else makes them change.
