When an object is at rest, this is the force that opposes (acts against) future motion.
Back
Reaction force
Front
The paired force that "pushes/pulls back" on the action force
Back
Inertia
Front
The principle which states that an object in motion will stay in motion unless stopped by an outside force, and that an object at rest will stay at rest unless moved by an outside force.
Back
Dynamic Friction
Front
When an object is moving, this is is the force that acts against the direction of an object's motion and slows/stops it.
Back
Component
Front
One part of a group of objects that, together, form a complete unit
Back
Contact force
Front
The force that exists between two objects that are touching one another.
Back
Net force
Front
The combination of all forces acting on an object, represented by a single arrow
Back
Action force
Front
The force that begins an interaction between two components
Back
Force at a distance
Front
Forces that exist between two objects that are not touching one another. Examples include: gravitational forces, electrical forces, magnetic forces
Back
System
Front
A collection of components that interact with each other
Back
Force
Front
A push or a pull in a specific direction
Back
Paired forces
Front
Action and reaction forces. For every force that acts on a component, the component reacts with an equal force, of the same kind, in the opposite direction.
Back
Magnitude
Front
The size, or amount of something, for instance the strength of a force.
