Physics Flashcards

Flashcards for key concepts in physics, including energy forms, heat transfer, magnets, and motion.

Kinetic Energy

Movement energy.

Gravitational Energy

Energy stored in objects at a height.

Elastic Energy

Energy stored in stretched objects e.g. a spring.

Chemical Energy

Energy stored in chemicals e.g. fuels, batteries and food. It is released by chemical reactions.

Loft Insulation

Reduces conduction and convection by trapping air.

Double Glazing

Reduces conduction by having a trapped gas and inefficient convection currents.

Draught Excluders

Blocks convection.

Aluminum Foil

Reflects infrared heat.

Cavity Wall Insulation

Traps air to reduce conduction and convection.

Carpet

Reduces conduction.

Expand

Liquids and gases do this when heated.

Thermal Conductivity

How good a material is at transferring thermal energy.

Insulators

Materials that are bad at transferring thermal energy.

Conductor

A material that allows thermal energy to be transmitted through it easily.

Radiation

Heat transfer by waves; doesn't need particles.

Insulator

Poor Thermal Conductor.

South Pole

The north pole of the earth is a magnetic .

Deformation

When objects are impacted, the bonds compress and the object squashes; this is called .

Tension

When objects are stretched, the bonds undergo .

Current

The amount of charge flowing per second.

Ammeter

Measured in Amps (A) and placed in series.

Parallel circuit

Has more than one loop; if one component breaks, the rest of the circuit still works.

Series Circuit

Has only one loop; if one component breaks, the whole circuit stops working.

Potential Difference

The amount of energy transferred by the cell or battery to the charges.

Nucleus

The central part of an atom containing protons and neutrons.

Static Electricity

Caused by the rubbing together of two insulators.

Resistance

A measure of how easy or hard it is for charges to pass through a component.

Insulators

Materials with a high resistance.

Conductors

Materials with a low resistance.

Elastic Object

An object that can be stretched or compressed and return to its original size.

Speed

How far something moves in a given amount of time.

Acceleration

A change in motion.

Electromagnets

Fancy magnets which you can turn on and off.

Solenoid

A long coil of wire that acts like a bar magnet when a current flows through it.

Magnetic Energy Store

Materials that can attract or repel other magnetic materials.

Gravitational Potential Energy Store

Objects that are lifted against the force of gravity.

Kinetic Energy Store

Objects that are moving.

Chemical Energy Store

Energy in the chemical bonds between atoms and molecules.

Nuclear Energy Store

Energy in the nucleus of atoms.

Thermal Energy Store

Another name for heat energy.

Elastic Energy Store

Objects that are stretched or compressed.

Electrical Energy Store

Energy carried by electric charges.

Mechanical Energy Transfer

Applying a force.

Electrical Energy Transfer

Moving charges.

Heating Energy Transfer

Applying thermal energy.

Radiation Energy Transfer

Transfer of energy by waves.
