A push or pull extorted on an object in order to change the motion of the object; force has size and direction
Combination of all the forces acting on an object
Tendency of an object to resist any change in motion or a moving object resisting motion until another force acts on it
A force that opposes motion between two surfaces that are in contact
A measure of the amount of matter in an object
A measure of the gravitational force exerted in an object; can change
Constant velocity of a falling object when the force of air resistance is equal to the magnitude and direction of gravity
Force of attraction between two objects due to their masses
Force that opposes motion of objects through air
The motion of a body when only the force go gravity is acting on the body
the curved path that an object follows when thrown, launched, or otherwise projected near the Earth's surface
Newton's 1st Law
An object at rest remains at rest and an object in motion remains in motion at a constant speed in a straight line unless disturbed by an unbalanced force
Newtons 2nd Law
The acceleration of an object depends on the mass and force applied
Newton's 3rd Law
Whenever one object exerts a force on the second, the second object exerts an equal and opposite force on the first
When the net forces produce 0 N; do not cause a change in the motion of a moving object and don't cause nonmoving to move
When the net force is not 0 N; produce a change in motion such as speed or direction, necessary to cause a nonmoving to move
An objects change in position relative to a reference point
a quantity defined as the product of the mass and velocity of an object
Law of conservation of Momentum
Any time objects collide the total amount of momentum stays the same
