Forces that produce a nonzero net force, which changes an objects motion
Speed
The distance an object travels per unit of time
Momentum
The product of an objects mass and velocity
Net Force
The overall force on an object when all the individual forces acting on it are added together
Gravity
The force that pulls objects toward each other
Potential Energy
Stored energy that results from the position or shape of an object
Velocity
Speed in a given direction
Weight
The force of gravity on an object at the surface of a planet
Friction
The force that one surface exerts on another when the two surfaces rub against each other
Newton
A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second
Balanced Force
Equal forces acting on an object in opposite directions
Inertia
The tendency of an object to resist any change in its motion
Kinetic Energy
Energy that an object has due to its motion
Motion
The state in which one object's distance from another is changing
Acceleration
The rate at which velocity changes
Newtons First Law of Motion
"An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocit, unless it is acted upon by an unbalanced force." Another name is Law of Inertia
Mass
The amount of inertia depends on this
Newtons Second Law of Motion
"Acceleration depends on the objects mass and on the netforce acting on the object."
Equation of Force, Mass, and Acceleration
Acceleration=Netforce/ Mass
N and kg*m/s^2
The same unit of measurement
Force= Mass* Acceleration
How you can use Newtons Second Law to find force
Increase the Acceleration of an Object
Increase the force, or decrease the mass
Newtons Third Law of Motion
"If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object."
Action Force
The name often given to the force exerted by the first object on a second object
Reaction Force
The name often given to the force exerted by the second object back on the first object
Equal and Oppsite Reactions
The action and reaction forces in any situation will always be this
Momentum=Mass*Velocity
To determine an objects momentum
Meters Per Second
Unit of measurement for momentum
Law of Conservation of Mass
"The total momentum of any group of objects remains the same, or is conserved, unless outside forces acts on the objects."
