14

what deals with magnitude and direction

vector

15

what are the characteristics of a vector

displacement
velocity
acceleration
force

16

force is a ______

vector

17

what is a sum of all vectors on a given object?

force (net force)

18

does zero net force constitute zero forces acting upon an object

no

19

what law and who made it?
an object will remain at rest or in motion indefinitely unless a net force act upon it? (inertia)

Newton's
law of motion #1
(inertia)

20

what law and who made it?
force is proportional to a specific mass and an acceleration in a specific direction

Newtons
law of motion #2
(force)

21

what law and who made it?
for each force exerted on one body, there is an equal, but oppositely directed force on some other body interacting with it

Newtons law
Law of motion #3

22

how to remember the laws (just for me you may not like)

1st- you'll remain in motion unless something acts upon you
2nd- the force you are moving is proportional to your mass and acceleration
3rd- while going there is a constant force against you interacting with it

23

explain force when a man is pushing a car!

- man applies 1 force to car
- man applies one force to ground (friction coeff)
-Car applies force to ground (friction Coeff)
-car applies force to man
- gravity applies force to car and man
-molecules in the air applying resistance

24

what is the standard unit of measurement of force

newton

25

equation for force?

force= mass x acceleration

26

Equaion for newton

newton = kg x m / s^2

27

what is a newton in layman's terms

the amount of force required to move one kg of an object one meter per second squared

28

mr. miller is 116kg is that his weight?

no it's his mass

29

what is the difference b/t pounds and kg

pounds are weight
kg is mass

30

weight is a measure of what?

mass in accordence with its gravitational relationship
