Question 1

Newtons 1st Law

Answer 1

anything in motion stays in motion unless acted on by an outside force

Question 2

Newtons 2nd Law

Answer 2

the amount of acceleration depends on the size of mass and the amount of force

Question 3

Newtons 3rd Law

Answer 3

for every action there is an equal bot opposite reaction

Question 4

3 factors that affect whether or not an object will reach terminal velocity

Answer 4

-height at which it was dropped
-mass of the object
-surface area of object

Question 5

4 factors that affect the amount of friction between surfaces

Answer 5

-type of material
-texture
-surface area in contact
-force pushing

Question 6

2 factors that affect the amount of air resistance on an object

Answer 6

-velocity of object
-amount of surface area

Question 7

2 factors that determine how much gravitational force between objects

Answer 7

-mass of object
-distance between objects

Question 8

Law of Conservation of Momentum

Answer 8

when an object collides with another object the momentum of the original object will give some or all momentum to the other object

Question 9

define 4 fundamental forces

Answer 9

strong nuclear -holds nucleus together
electromagnetic -force between charged particles
weak nuclear-force that decays neutron to a proton
gravity -force between 2 objects
