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

###
Fc=4TT^2rm/T^2

r-radius

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
