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
