Forces And Motion Flashcards
A _________ force is exerted when objects are touching.
Contact force
A push or a pull with size and direction.
Force
A _______ force is exerted when objects are not touching.
Non-contact force
Two equal forces that cancel each other out because they are acting in opposite directions on the same object, the objects motion does not change.
Balanced force
An object’s motion will change if _________ forces act on it.
Unbalanced
_________ force is the difference between two forces.
Net force
A non-contact force that every object exerts on every other object due to their masses.
Gravity
A force that resists motion between two touching surfaces.
Friction
_______ friction is the force between two surfaces in contact that keeps them from sliding when a force is applied! must be overcome to start moving.
Static
_____ friction opposes the motion of sliding objects.
Sliding friction
______ opposes the motion of objects moving through the air.
Air resistance
______ force is an upward force exerted by fluids.
Buoyant
