Flashcards in lab midterm Deck (20):
1

ratio

relation between two objects
quantitiative

2

mass

measure of objects inertia
state of rest

3

volume

space an object takes up

4

metrics

khfodcm
kids have fallen over dead converting metrics

5

0%
error

/(experimental value-accepted value/av)/ x 100

6

slope

y1-y2/x1-x2

7

centripetal force

Fc=4TT^2rm/T^2
r-radius
m-mass
T-period
center seeking force

8

UNITS
Force

Power
Centripetal Force
Specific Heat


Newton ma
Jules mad
Watt W/t
Newton
calories/g^0C

9

solenoid

coiled length of wire

10

electricity

the change in charge with the movement of electrons from a greater concentration to a lesser concentration

11

ferromagnetic

iron...strong magnetic properties at room temperature...iron cobalt nickel gadolinium

12

electromagnet

created by placing a piece of iron in the center of a solenoid creating stronger field

13

specific heat

amount of energy required to change temp of 1g of material 1^0 C

14

g

acceleration due to gravity 9.8m/s^2

15

meniscus

curve of upper surface of liquid...measurement taken at center of curve

15

1st law of motion

Object at rest stays at rest
Object in motion stays in motion

16

2nd law of motion

F=ma
Object moves in direction pushed
If O1 weighs 2x O2 & you apply same force to both...O2 will go 2x farther

17

3rd law of motion

For Every action there is equal and opposite reaction

18

Constant velocity

Acceleration is equal to zero

19

Non constant velocity

Acceleration not equal to zero
