16
Q

scientific law

A

a statement about a theory that has been tested even more and still had the same result (like eating a ton of candy will get you sick………maybe i should…….retest it……a couple more times) :D

17
Q

volume

A

amount oif space in a thing like a bucket or a bag…….for candy :D (scientific law)

18
Q

mass

A

the amount of stuff in a thing like a candy bag with lots of mass………..is a good thing

19
Q

matter

A

anything that has mass or takes up space

20
Q

meter

A

SI unit for length

21
Q

gram

A

SI unit for mass

22
Q

ml

A

one thousandth of the SI unit for volume (it’s a bad thing to only have 1 mL of candy)

23
Q

cubic cm

A

a measurement that is pretty much the same as a mL (note the rubik’s cube)

24
Q

velocity

A

measurement of speed wid direction (with one direction :D)

25
Q

Acceleration

A

rate @ which velocity changes (now how can i bring that back to 1D…..oh well ONE DIRECTION!!!!)

26
Q

potential energy

A

by an objects postion how much energy it will have

27
Q

Kinetic energy

A

energy of an object because its moving

28
Q

momentum

A

the thing you gain as you race out of the classroom on the last day of school and the teacher says “i need to have a word with you” OR if you want the boring answer its the mass times velocity of an object

29
Q

Friction

A

force opposing motion when two objects touch

30
Q

Newton’s laws of motion

A

annoying…… but if you want the “right” answer its 1.) an object in motion stays in motion, an object at rest stays at rest 2.) when an unbalanced force acts on an object the object will shoot off in the directio of the unbalnced force 3.) when A acts on B, B will act with equal force on A

31
Q

fulcrum

A

rigid point or support at which a lever pivots (the part of a machine thtat’s to blame when your doing something and it spins up and hits your face)

32
Q

Work

A

a transference of energy (sounds painful…….)

33
Q

joule

A

a newton meter or a measure of energy/work (should be the name of a zany fruity candy)

34
Q

power

A

measure indicating rate of doing work (MAXIMUM POWER!!!!)
