Motion
Change of position
Force
A push or a pull; measured in Newtons.
Work
Force across a distance. The wall was pushed with a force of 100 N and it moved 2 cm. 200 Joules of work was done on the wall.
Joule
Units for work.
Acceleration (47)
the rate at which velocity changes
(F.V. - O.V. / T)
Net force
The combination of all forces acting on an object. Ava applied 20 Newton of force and Summer applied 20 Newtons of force (both in the same direction) to a table. Their net force would be 40 Newtons. Subtract when forces are in opposing directions.
Friction
the force opposing the motion of surfaces
Fluid, sliding, rolling and static are all types of friction.
Gravity
Invisible force of attraction due to mass and distance.
Velocity
Speed in a given direction
Speed (39)
The distance an object travels per unit time. Speed is a rate. S=D/T
Balanced Forces
equal forces acting on one object in opposite directions. Object will not be moving. Similar to static friction.
Newton's 1st. Law (54, 55)
The "Inertia" law. Objects at rest/motion will stay at rest/motion until an outside, unbalanced force acts upon it.
Inertia (54)
The resistance to motion. The higher the mass, the higher the inertia. Seat belts are inertia belts. R.M.
Newton's Second Law
Force = Mass x Acceleration.
Changing one will affect the rest. If you increase the mass, the acceleration will decrease. If you increase the force, the acceleration will increase.
Newton's Third Law
for every action there is an equal and opposite reaction
Momentum
Mass x Velocity
Model
A representation of something too big, small, extinct, dangerous, etc. to have in a lab.

Compound
Two or more elements chemically combined
Density
How tightly-packed something is. D=M/V.
1.0 g/ml is the density of water.
