Newton's Laws
Terms in this set (15)
Force
A push or a pull.
Speed
The distance an object travels in a certain period of time. (Speed=Distance/Time.)
Acceleration
The change in velocity over time.
Inertia
An object's resistance to change in its motion. (MORE mass = MORE Inertia)
Mass
The amount of matter in an object.
Gravity
The force of attraction that exists between all masses in the universe.
Weight
A gravitational force exerted on an object's mass, that changes with position.
Momentum
A property of any MOVING object. The momentum (p) of an object is the product of its mass and velocity according to the equation p=mv.
Friction
The force that OPPOSES or acts against motion when two surfaces rub against each other.
Action and reaction
Newtons 3rd law
F=MxA
Newtons 2nd Law
Object in motion stays in motion objects at rest stay at rest
Newtons 1st law
Drag
A force that creates air resistance
Thrust
The force that moves and object
Lift
Force that acts perpendicular to motion
