1

sig fig rules

- all none zero digits in a measurement are significant
- zeroes that come after the decimal and after a none zero digit are significant
- leading zeroes are not significant
- trailing zeroes with no decimals are assumed to not be significant

2

2 large categories of motion

- constant velocity
- acceleration

3

position

the direction or place of an object

4

distance

How much ground an object has covered during its motion

5

displacement

a vector quantity which refers to how far out of place an object is

6

speed

how far an objects moved in a certain amount of time

7

velocity

movement

8

acceleration

increase in the rate/speed of something

9

Kinetic energy

Energy an object possesses because of its motion

10

Potential energy

Energy of position

11

Inertia

Ability of an object to resist change in motion

12

Momentum

The product of mass and velocity

13

Force

A push or pull

14

3 safety features in vehicles using newtons law

Airbags, crumple zones, seat belts

15

Airbags

When a collision occurs, they extend time which slows down the force experienced by the passenger

16

Seat beats

Keep the passengers travelling at the same speed as the car which keeps them from being thrown due to inertia

17

Crumple zones

Engineers designed cars to crumple, absorbing kinetic energy as distribution of force over time is applied

18

Impulse

The product of force and time

19

Newtons 3 laws

- objects will remain at rest or in a straight line uniform unless acted upon an unbalanced force
- acceleration is directly proportional to force and inversely proportional to mass
- for every action there is an equal and balanced reaction

20

Rules for adding and subtracting

Your calculated value should have the same precision as your least precise measurement

21

Rules for multiplying and dividing

Your calculated value answer should have the same number of sigfigs as the least sigfigs in your measurement
