Physics equations and important things Flashcards
Draw out the physics flow chart
Write out all the Unit conversions and mnemonic
The Great Man King henry died upstairs drinking chocolate milk miserably not peacefully
write out kinematic equations.
When are kinematic equations applicable ?
when acceleration is constant
What are the different types of energies? Write out their equations
gravitational
kinetic
spring
electrostatic
chemical
What are the 2 types of friction and their equations
static friction- the frictional force when an object is not moving
kinetic friction- the frictional force when an object is moving
write out the full sin and cos table
What is torque and the equation for torque
the force that causes an object to rotate about an axis
What is mechanical advantage and its equation
Mechanical advantage is the advantage one gets when using a simple machine to decrease the force required to do the same amount of work
Eqution and units for pressure
P=F/A
Pressure = Force/ Area
pascals
1 atm ~ 100,000 Pa
Pascal’s Law
pressure applied to a confined fluid is transmitted equally thorughout fluid in all directions
P1=P2
V1=V2
W1=W2
Equation for total pressure of a hydrostatic fluid
Density equation and density of water
Rho (density) = m/v m/v looks like a heart ❤️
density of water = 1000kg/m^3
Force of buoyancy
Fb=Fg = mg = rho gV
Continuity of flow fluid equation
Q=VA
Q=flow rate
V=velocity
A= cross sectional area
Qin=Qout
poiseuille’s Law
Describes the flow rate of a fluid through a tube and how various factors, such as pressure and viscosity, affect it.
It is helpful in describing laminar flow in blood, airways, etc.
Bernoulli Equation
describes the conservation of energy in a flowing fluid and relates pressure, height, and vwlocity.
Helpful to know that when pipe becomes restricted, pressure decreases and velocity increases and vice versa.
Venturi effect.
electrostatics equations
FUVE
F=force
U = energy
V= Voltage (J/C
E= Electric Field (N/C)
Equation for magnetic field
Right hand rule to determine direction of magnetic field
To find magnetic field (B)
Thumb- direction of current
Fingers- curl to get direction of MF
Equations to determine force exerted by magnetic field on other moving charges like particles and currents
