newtons laws

QuestionAnswer
Force Push or Pull
Unbalanced Force 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
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
Motion The state in which one object's distance from another is changing
Potential Energy Stored energy
Kinetic Energy Energy that an object has due to its motion
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."
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."
