• A system where energy can be transferred but not created or destroyed

• A system where energy can only be transferred out

What is the formula for calculating work done?

• Work = Force × Distance

• Work = Force + Distance

• Work = Power × Time

When an object is accelerated by a constant force, which energy store is involved?

• Kinetic energy

• Chemical energy

• Efficiency = Useful energy output / Total energy input

• Efficiency = Total energy input / Useful energy output

• Efficiency = Useful power output / Total power input

• Both A and C

For electrical charge to flow through a closed circuit, the circuit must include which of the following?

• P = IV

• Q = It

• E = Pt

In a series circuit, how does the total resistance compare to the resistance of individual resistors?

• It is the same as the smallest resistor

• It is the same as the largest resistor

• It is the sum of the resistances of all resistors

What is the definition of density?
