who is the father of physics
Galileo
Fnet = ma
Newton's Second Law
one guy pulls wire on a pole north 300N and 200N
a2 + b2 = c2
change in v/ change in t
average acceleration
I KNOW THE PRESSURE, RADIUS AND VELOCITY AT THE NOZZLE DISCHARGE POINT. I WANT TO KNOW THE PRESSURE UPSTREAM IN THE SUPPLY HOSE. SOMEONE GAVE US A FORMULA
bernolius
any net force causing uniform circular motion is called
centripetal force
mr.a has a wood stove with a built in fan
convection
m1v1i+m2v2i=m1v1f+m2v2f
elastic collision
a rock at a edge of class does not move so it has stable equilibrium
false
is gas is 2 a gallon the Mazda gets more equivalent miles than a Nissan at typical peco rates
false
the package label on a gronala br says 200 cals per serving the label is correct a factor of 100
false
W= v/rm
find the angular velocity
net F =0
first equilibrium
F= m * a
friction
m1v1+m2v2=(m1+m2)v
inelastic equation
1/2 m2
kinetic energy
gas, liquids, plasma
liquids
on level horizontal surface the normal force is determined by 2 qualities
mass and gravity
which accounts for most energy in th world as per 2018 data
natural gas and oil
one body exterts a force on a second body
newtons 3rd law
kinetic friction (fk)
opposes the motion of objects moving relative to each other
pitot tube
p1= p2 + 1/2 pv2
pressure
p= d* g * h
W/t
power
only magnitude
scalar
T= r8 f 8 sin
second condition of equilibrium
a 28000kg cement block has a volume of 10m3 will it sink or float
sink
Q= mcΔT
specific heat
a force along the length of a medium, especially a force carried by a flexible medium such as a rope or cable
tension
a runner who runs for 11 miles in 3 hours does this guy or a college student have a faster metabolism
the college student
10 gram bal moving at 10m/s elastically has another 10 gram ball moving at -10m/s what would happen to the balls
they would bounce off each other at 10m/s and 10 m/s
a centrifuge can create acceleration for greater than gravity
true
as a the angle of steepness increase the stairs goes faster because the normal force decreases and friction decreases
true
change of x/ change of t
velocity
w= f d cos
work
a car starts at point t zero equation
x= x0 + Vt
well equation
y= y0 + v0t - 1/2 gt2
on eguy pull north on a pole at 100N. another guy wire pulls south at 1000N what is Fnet
zero
