control group

• standard for the experiment being tested against.

• particles with charge of 1-, surrounds the nucleus of an atom.

• form of waves and particles

• hot air rises cold air sinks

hypothesis

• in an experiment a variable that does not change.

• factor that changes a result of change in the other variables.

• possible explaination for a problem using what is known and what is observed.

• particles in the nucleus with an electric charge of it.

factor that changes a result of change in the other variables.

• conduction

• convection

• momentum

• dependent variable

constant

• in an experiment a variable that does not change.

• transfer of thermal energy by collision between the particles that make up matter.

• circuit in which electric current has only one path to follow

• it measures how many volts you have.

factor that, as it changes, affects the measures of another variable.

• work

• protons

• independent variable

• dependent variable

states that an objects moving at a constant velocity keep moving at that velocity unless an unbalanced force acts on it

• newtons 3rd law

• newtons 1st law

• newtons 2nd law

• radiation

newtons 2nd law

• states that the acceleration of an object is in the same direction as the net force on the object .net force divided by mass.

• property of a moving object that equals its mass times velocity

• circuit in which electric current has only one path to follow.

• measure of average kinetic energy and potential of particles that makes up an objects.

newtons 3rd law

• property of a moving object that equal it's mass times its velocity

• equal and opposite reaction

• standard for the experiment to be tested against

• in an experiment a variable that does not change

property of a moving object that equal its mass time its velocity

• temperature

• electrons

• momentum

• convection

states that if no external force act on a group of objects their total momentum does not change.

• conduction

• work

• static electricity

• law of conservation of momentum
