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)

(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.

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.

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.

1.0 g/ml is the density of water.
