Force & Newton's Laws Vocab

A push or pull on an object.
Net Force
The combination of all the forces on an object.
Balanced Forces
They cancel each other out and do not change an object's motion.
Unbalanced Forces
The motion of an object changes.
Force that resists sliding between two touching surfaces or through air or water.
Kinetic Friction
Friction that occurs when two objects in contact slide past each other.
Attractive force between two objects; depends on the mass of the objects and the distance between them.
Gravitational force.
Air Resistance
A form of friction that acts to slow down any object moving through the air.
A force that opposes motion of an object when an object moves through a fluid.
Newton's 1st Law of Motion
An object will remain at rest or move with constant speed unless a force is applied.
Newton's 2nd Law of Motion
Connects force, acceleration, and mass; it explains that an object acted upon by a force will accelerate in the direction of the force; acceleration equals new force divided by mass.
Newto's 3rd Law of Motion
States that forces always act in equal but opposite pairs; for every action there is an equal and opposite reaction.
Applied Force
Force applied to an object.
Normal Force
Support force.
