Q: What is the formula for Ohm's Law?

Back

V = I × R
Voltage = Current × Resistance

Front

How do you calculate electrical power?

Back

P = V × I or P = I² × R
Power = Voltage × Current
or
Current squared × Resistance

Front

What is the formula for wave speed?

Back

A: v = f × λ
Wave speed = Frequency × Wavelength

Front

How do you calculate acceleration?

Back

A: a = Δv / t

Change in velocity ÷ Time

Front

What is the formula for weight?

Back

W = m × g
Weight = Mass × Gravitational field strength

Front

How do you calculate kinetic energy?

Back

KE = ½ × m × v²
Kinetic energy = Half × Mass × Velocity squared

Front

What is the formula for work done?

Back

F × d
Force × Distance

Front

How do you find density?

Back

m / V
Mass / Volume

Front

The formula for potential difference (V) is:

Back

V = E / Q
PD= Energy transferred / Charge
