Gravity & Newton

Gravity and Newton's Laws of Motion Terms

TermDefinition
Force A push or pull that causes an object to move, stop, or change direction.
Motion A change in an object's position with respect to time and in comparison to other objects.
Mass The amount of matter in an object; Affects gravity, friction, and acceleration.
Acceleration An increase in speed.
Friction A force that slows things down; It resists the motion of two surfaces sliding across one another.
Contact A meeting or touching of surfaces
Gravity A force of attraction between two or more objects that pulls; It increases with the mass of objects and decreases with distance.
Newton's 1st Law- Inertia Objects in motion will stay at motion, while objects at rest will stay at rest until an UNBALANCED force acts on it.
Newton's 2nd Law- Force, Acceleration, and Mass The greater the force applied to an object, the greater the acceleration. Also, the greater the mass of an object, the greater the force needed to accelerate the object.
Newton's 3rd Law- Action and Reaction Deals with objects in pairs. States that for every action, there is an EQUAL and OPPOSITE reaction.
Weight The force of gravity on an object's mass.
Balanced Forces When the forces acting on an object are in opposite directions, and are equal in size (Newtons/N), and the object DOES NOT MOVE.
Unbalanced Forces When the forces acting on an object are are not equal in size, and come from the same direction, and causes the object to MOVE.
Net Force The total of all forces acting on an object. The size of the net force is the difference of the forces.
