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

44

One km = ------m
