Physics Formulas.

What is the equation for charge?

• Charge = Current / Time

• Current = Time / Charge

• Charge = current x time

• Charge = current² x time

What is the equation for Voltage?

• Voltage = Resistance / current

• Voltage = Current x resistance

• Voltage = resistance / the number of components

• Voltage = Current x time

State Ohm's law.

• Resistance = Voltage / current

• Voltage = Current x resistance

• R = V / I

• V = I² x R

Current is equal to :

• Voltage / Resisitance

• Voltage x Resistance

• Resistance / Charge

• Resistance / flow of electrons per second.

Kinetic energy can be calculated using :

• Mass = Kinetic energy² x 1/2

• Kinetic energy = speed / 2 x mass

• kinetic energy = (mass² x speed) x 1/2

• Kinetic energy =(mass x speed) /2

Gravitational potential energy is measured by ...

• mass x gravitational field strength x height

• {mass ² x gravitational field strength x height }/2

• Mass x gravity

• Force x gravity x mass x height

Weight =

• mass x gravity

• gravity / mass

• gravity x force

• force / gravity

What is the formula for work done?

• Work done = Distance / force

• Work done = Force x distance

• Work done = Force / distance

• Work done = Mass x distance

Power =

• Energy / time

• Energy x force

• Energy x time

• Time / energy

Time :

• Energy² x power x (1/2)

• Energy x power

• Energy / power

• (Energy x power) / 2
