[1.1]
What is a significant factor of resistance?
A significant factor of resistance is temperature.
What is another common term for energy transferred?
Energy transferred can also be described as work done.
[1.2]
Give the formula for kinetic energy.
Eₖ = ¹/₂mv²
Energy = ¹/₂ x Mass x Velocity²
[2.1]
What is potential difference in a circuit?
In a circuit, potential difference is the force that drives the flow of electrons.
[2.1]
What is potential difference measured in?
Potential difference is measured in Volts (V).
[2.1]
What is resistance in a circuit?
In a circuit, resistance is the opposition to the flow of electrons.
[2.1]
What is resistance measured in?
Resistance is measured in Ohms (Ω).
[2.1]
[1.3]
, 2
Give the formula for gravitational potential energy.
Eₚ = mgh
Energy = Mass x Gravitational Strength x Height
[1.4]
Define temperature.
Temperature is a measure of the average internal energy within a substance.
[1.4]
What is specific heat capacity?
Specific heat capacity is the amount of energy required to raise the temperature of 1kg of a
substance by 1°C.
[1.4]
Define internal energy.
Internal energy is the total energy stored in the particles of a system.
[1.4]
What are the 2 types of internal energy?
Internal energy can either be potential energy, or kinetic energy.
[1.4]
Give the formula for specific heat capacity.
△E = mc△0
Energy change = Mass x Specific heat capacity x Temperature change
[1.6]
How does temperature spread in solids, fluids and empty space?
Temperature spreads in multiple ways:
- Solids - Conduction, vibrating particles pass energy
- Fluids - Convection, particles collide and spread energy
- Empty space - Radiation, waves carry energy
[1.7]
Give the 2 most common ways to reduce unwanted energy transfers.
, 3
Unwanted energy transfers are most commonly reduced through thermal insulation or lubrication.
[1.8]
Define power.
Power is the rate at which energy is transferred.
[1.8]
Give the formula for power.
P=e/t
Power = Energy / Time
[1.9]
What is efficiency?
Efficiency is a measure of how effectively energy is transferred.
[1.9]
Give the formula for efficiency.
Efficiency = Useful output / Total output
[1.10]
Give the 2 types of energy sources.
Energy sources can be categorised into:
- Renewable, replenished faster than it is used
- Non-renewable, replenished slower than it is used
[1.10]
What are the 3 forms of hydrocarbon?
Hydrocarbons can either be coal (solid), oil (liquid) or natural gas (gas).
[1.10]
How do hydrocarbons form?
Hydrocarbons form as a result of fossils being buried and compressed over millions of years.
[2.1]
What is an electrical circuit?
An electrical circuit is a closed loop consisting of a power source and a wire.
