Series resistors

Front

a continuous usage of resistors.

Ohm's Law

Front

states that the voltage is equal to the current (amperes) multiplied the resistance.

Back

weight

Front

how much an object weighs

Back

displacement

Front

the distance from two different positions; ex: point A is 5 m from point B, thus its displacement is 5 m.

Back

inelastic collision

Front

Two colliding objects stick together to become one.

Back

Center of mass

Front

part of the system that is used as a basis for measuring external forces.

Stored energy an elastic object has; ex: a rubber band.

Back

Coefficient of Friction

Front

the amount of friction (ratio) needed to an object across a surface.

Back

Resistance

Front

opposing a force from going through a current.

Back

Newton's 3rd law

for every action there is an equal or greater action.

Back

Electric current

Front

The flow of an electric charged carried through a wire.

Back

Elementary charge

Tool used to measure electric currents in amperes (amps).

Back

Kirchhoff's Law

Front

the sum of all currents going into a node is equal to 0.

Back

Coulombs Constant

Front

is the electrical force constant/ electrostatic.

Back

Force of Friction

Front

the force that acts on an object that moves in the opposite direction of your normal force.

Back

Force tension

Front

force that is acted on a rope, when it is outstretched.

Back

Coulombs Law

Front

"The force of attraction or repulsion acting along a straight line between two electric charges."

Back

Normal Force

Front

the force that is perpendicular to the surface of the object

Back

Static friction

Front

the friction on an object where the object is at rest

Back

Conservation of Momentum

Front

When a system has momentum equal through the whole system. Consider Newton's 1st law.

Back

elastic collision

Front

When the kinetic energy of two colliding object's is equal to the resulting energy.

Back

velocity time graph

Front

shows the objects velocity at a given time.

Back

parallel resistor

Front

closed circuit that divides into two or more paths. Both paths get the full circuit voltage.

Front

acceleration is equal to the objects net force.

Back

Newton's 1st law

Front

any object stays in motion until acted on by an outside force.

Back

Kinetic friction

Front

the friction on an object when it's moving.

Back
