Physics Formulas Flashcards
1
Q
Momentum
A
P = MV
Momentum = Mass x Velocity
2
Q
Current
A
I =Q/T
Current = Charge / Time
3
Q
Ohm’s law
A
V = IR
Voltage = Current x Resistance
4
Q
Power (Electrical)
A
P = IV
Power = Current x Voltage
5
Q
Wave speed
A
v = f x λ
Wave speed = frequency x wavelength
6
Q
Pressure
A
P = F/A
Pressure = Force / Area
7
Q
What is Newtons first law?
A
An object will remain at a constant speed or at rest unless acted on by an external force
8
Q
What is Newtons second law?
A
Force acting on an object is directly proportional to the mass and acceleration
