Flashcards in Motion And Newtons Laws Deck (48):

1

## How does inertia affect motion

### Inertia resists change so more inertia means less change in motion

2

## Will inertia of an object cub age if it goes to the moon

### No objects will stay in motion unless acted on by another force sense gravity affects weight not the mass

3

## What does inertia affect

### Mass

4

## What does gravity affect

### Weight

5

## What is the formula for speed

### Speed=d/t

6

## What is the formula for finding average speed and

### Total distance/ total time

7

## What does constant acceleration look like on a d T graph

### Curving up

8

## What does constant velocity look like on a d t graph

###
Straight increasing line

Or straight horizontal line

9

## What does constant velocity look like on a s t graph

###
just straight horizontal line

10

## What does constant positive acceleration look like on

### Straight increasing line

11

## How does a dot and arrows map show constant acceleration

### By the dots space doubling in size each time, accelerating the same constant speed

12

## Distance formula

### D=s X t

13

## What is a vector quantity

### A quantity that includes magnitude and direction

14

## What are two examples of vector quantities

### Velocity and force

15

## How is inertia related to mass

### More mass equals more inertia

16

## What is velocity

### Speed in a direction

17

## What is Newton's first law motion

### Law inertia, objects at rest tend to stay at rest, objects in motion to stay in motion unless acted on by an outside force

18

## What is net force

### Combination of all force vectors

19

## What types of motion will have net forces of zero

### At rest, balenced, constant velocity

20

## What is support force

### The force acting against gravity, normal force

21

## What formula is given by Newton's second law

### Force= m X a

22

## The acceleration due to gravity is

### 10/m/s/s

23

## How are acceleration and net force related

### When force increases so does acceleration

24

## How is mass of an object related to its acceleration

###
When mass increase

Acceleration decrease

Curving down slope

25

## What is friction

### A force that opposes motion

26

## What is weight

### Is amount of force generated by the effect of gravity in the mass

27

## What is mass

### Mass is amount of matter in an object

28

## Is mass or weight a force

### Weight is a force mass is not

29

## What will change when you go to the moon

### Weight

30

## Acceleration formula

### A= f/m

31

## How to convert newtons weight into mass

###
'N= kgX 10 m/s/s

So n/ 10 m/s/s = kg

32

## If force us doubled then the acceleration will

### Double

33

## If mass is doubled then the acceleration will

### Be halved

34

## What is the weight of a 90kg man

### 90kg X 10m/s/s = 900N

35

## What is another formula for acceleration

### A= vf-vi/t

36

## Centripetal acceleration

### Moving constant velocity in circle, feel like moving to the outside because of inertia but acceleration is pointing to the inside

37

## Gravitational force formula

### M + M2/ d squared

38

## Weight formula

###
Gravity X mass in kg

10m/s/s X kg

39

## Formula for force

### M X a

40

## What is a force

### Push in or pull in a certain direction

41

## What kind of number is deceleration

### Decimal

42

## One meter = ----- mm

### 1000

43

## One meter =------ cm

### 100

44

## One km = ------m

### 1000 meters

45

## One kg = ----- g

### 1000

46

## One meter =----inches

### 39.37

47

## One km = ----mi

### .62 miles
