### Law 1

An object in motion will stay in motion and an object at rest will stay t rest until acted upon b an unballanced force

### Law 2

how force mass and acceleration are related (force=mass*acceleration)

### Law 3

for every action there is an equal and opposite reaction

### Momentum

Mass of an object * it's velocity; determines how dificult it is to stop the object's motion

### force

a push or a pull that gives energ, sometimes causing a change in object's motion

law of intertia

### friction

surface resistance to relative motion, as of a body sliding or rolling

### false

true of false: law 1 has unballanced forces

### true

true or false: law 2 has unballanced forces

### 2

how many forces are constantly acting upon us

### pairs

al forces occur in ___

### momentum

depends on mass of object and velocity whith witch it is traveling

### momentum

all moving objects have ___ becausse of velocity

### true

true or false: the more momentum an object has the ahrder it is to stop (inertia)

### mass

an increase in ___ or velocity will increase momentum

### conserved

momentum is always ___

### 0

the movement of an object that is not moving is ___

### true

true or false: momentum is in the same direction as velocity of the object

### stationary

momentum can be transfered to a ___ object when they collide

### 0

in order for forces they need to have a net force of ___

### balanced

i forces are equal but in opposite direction they are ___

### unbalanced

if forces are equal but in same direction they are ___

### unbalanced

if forces are not equal but in opposite direction they are ___

### subtraction

if there is a change in momentum you combine by ___

### unbalanced

forces that change in position of an object are ___

### newtons

forces are measured in ___

### 0

a net force is ___
