Object

A collection of matter" Anything with matter - people, animals, things, earth, sun, everything

Force

An interaction between two objects a push or a pull

push/pull (applied force

Typically applied by a human

weight/gravity force

Force due to the attraction of an object to earth

Friction

A force caused by two surfaces rubbing together. this force resists motion

Normal

Depends on how much two surfaces are pushed together

Tension

A force exerted along a rope

spring/elastic

A force exerted by a spring

Buoyant

An Upward support force from a gas or a liquid

air resistance

A type of frictional force caused by motion through a gas or liquid

Weight

The forces due to gravity

Free body

Diagram that shows the forces that act on a object

Newton's 1st Law of Motion - (Law of Inertia)

An object at rest stays at rest and an object in motion stays in motion at constant speed in a straight line unless acted by an unbalanced force., An object without an unbalanced force will maintain a constant speed and direction., An object experiencing NO unbalanced forces experiences NO acceleration

Interia

A resistance to change in motion, related to mass, the more mass something has the more resistance to a change in motion.

An object cannot speed up, slow down, or change in direction

Without force

Injuries such as whiplash and concussions are

The result of Newton's 1st Law
