chap 3

Question 0

sliding friction

Answer 0

force that opposes the motion off 2 obj moving past each other

Question 1

static friction

Answer 1

force that prevents 2 obj frrom pushing past each other

Question 2

air resistance

Answer 2

a force that opposes motion of falling obj

Question 3

terminal velocity

Answer 3

the fasts speed a falling obj can reach

Question 4

gravity on earth

Answer 4

9.88 m/s2

Question 5

gravity

Answer 5

attractive foce b/w 2 obj

Question 6

depends of mass and distance

Answer 6

gravity

Question 7

equation for gravity

Answer 7

gravity force= mass x gravity

Question 8

newtons second law of motion

Answer 8

the acceleration of an obj will have the same directiona s the forces on the obj

Question 9

acceleration = net force / mass

Answer 9

acceleration equation

Question 10

newtons 3rd law of motion

Answer 10

for every action is an equal and opposite reaction

the action and reaction forces do not cancel each other out. they are applied to different obj

Question 11

newtons 3rd law deals with

Answer 11

momentum

Question 12

equation for momentum

Answer 12

momentum = mass x velocity

Question 13

the equation for weight

Answer 13

weight= mass x gravity

Question 14

Newton’s second law of motion deals with

Answer 14

accccerleration

Question 15

Gravity notes

Answer 15

if you increase the mass of an obj the force increases

if you increase the distance b/w obj the forces decrease
