Very VARIABLE Values
F
What is Force?
Lift up your calculator
Now you have your calculator :)
What is Newton (N)?
Equation for frequency
What is f = 1/T or n/t?
This means per second
What is Hertz?
mass
What is m?
Speed when you go 3 m in 2 seconds.
What is 1.5 m/s?
Unit for mass.
What is kilogram (kg)?
Equation for Work
What is W = Fd?
This is a Newton meter
What is a Joule?
What is Work OR Weight?
NOT WATTS (that's a unit :)
The acceleration if you use 10 N on a 5 kg object.
What is F = m a so a = F / m = 10 N / 5 kg = 2 m/s^2
Unit for energy
What is Joule (J)?
Equation for momentum
What is p = mv?
This is a meter per second
What is a m/s
Momentum
What is p?
The momentum of a 6 kg object moving at 2 m/s.
What is 6 kg * 2 m/s = 12 kgm/s?
Unit for weight
What is Newton?
Equation for Kinetic Energy
What is KE = 1/2 m v2?
N/m
What is current?
The current through a series circuit when the resistors are 10, 20, and 30 ohms with 5 V.
What is: R=60 Ohms, V= 5 V so I = V/R=5/60 = 0.08 Amps
Unit for Resistance
Equation for Efficiency
This is a Joule per second
What is a Watt?
