1
what is the sign for gravity in a free body diagram
fg
gravity
ff
fr
2
what is the sign for forward force
fr
ff
fg
fk
3
is there always an opposite force
yes
no
4
what is inertia
how much force is placed on an object before it moves
how fast something can reach a certain speed
the tendency for an object to resist a chance in motion
how long it takes to reach max speed
5
name the example of newtons 2nd law
an object in motion stays in motion unless acted on by force
It takes less force to push a bike than a motorcycle
A fireman turns on his hose & is knocked backwards
push a big ball harder so it moves as fast as the small one

what is the equation for weight
how much i ate this morning - how long i was in the bathroom
i have no clue
how much chuck Norris can bench press
fg=ma,g
8
what is static friction
help!
idk friction(duh)
the amount of friction you overcome before the object moves
an objects friction at rest
9
si unit of force is
cgs
kg
slug
force
10
if i am driving at a constant speed am i in equilibrium
idk
no
yes
maybe
11
what is the equation for newtons 2nd law
I have no idea
e= mc^2
f=m x a
f=9.81(t x a)
12
which is an example of newtons first law
Feet push down on the floor & the floor pushes your feet
12 lb bowling ball goes faster than a 15 lb bowling ball
How fast an object picks up speed
in a plane taking off you feel pushed back into your seat
13
what is force
friction that acts on objects at rest
a push or a pull on an object
speed in a given direction
the amount of matter in an object
14
witch is an example of newtons 3rd law
more force = more acceleration
A bowling ball hits the pins sending the pins flying
A soccer ball will not move until a player kicks it
for every action there is an = and opposite reaction
15
is force proportional to mass and acceleration
no
yes
16
is force a vector
no
yes
17
what is an example of coefficient friction
a banana peel
a sander
snowboard wax
water
18
Who was the scientist that concluded inertia?
Albert Einstein
Thelegend27
gillealio( thats how tanner says it)
Mr Johnston
19
does force exist in pairs
yes
no
20
what is newtons 2nd law
the distance an object travels per unit of time
How fast object picks up speed,slows down depending on mass
the tendency for an object to resist a chance in motion
an object at rest tends to stay at rest. an object in motion
21
what is newtons 3rd law
a law by some science guy
one thing bumps another thing, then same force is put back
that a thing in motion stays in motion
idk i wasn't paying attention
