MYP MYP Physics

The rearrangement of charges in a material caused by a nearby charged object, without direct contact.

An AC generator is a device that produces alternating current by rotating a coil in a magnetic field.

Acceleration is defined as the rate of change of velocity.

How close a measurement is to the true or accepted value.

Air resistance is the frictional force acting on objects moving through air.

An electric current that repeatedly reverses direction, typically produced by generators in power stations.

An electric current that repeatedly changes direction, typically produced by a generator.

A device used to measure electric current in a circuit.

The maximum displacement from equilibrium (or, for sound, the maximum pressure variation) of the oscillation.

A small rocky body that orbits the Sun, most commonly found in the asteroid belt between Mars and Jupiter.

Atmospheric pressure is the pressure exerted by the weight of the air above a surface.

The smallest unit of an element that retains the element’s chemical properties; it consists of a nucleus (protons and neutrons) with electrons around it.

The range of frequencies that a typical human can hear, about 20 Hz to 20 kHz.

An aurora is a natural light display caused by charged particles interacting with Earth’s atmosphere.

The ionizing radiation we are exposed to all the time from natural and human-made sources in our environment.

A model of the universe in which space has been expanding from a very hot, very dense early state, leading to the cooler, structured universe observed today.

An object with such strong gravity that, within a boundary called the event horizon, not even light can escape.

Boyle’s law states that pressure is inversely proportional to volume at constant temperature.

Describes a solid that breaks or shatters when deformed, with little permanent bending.

The random jittery motion of small visible particles (like smoke or pollen) caused by countless random collisions with much smaller molecules in a gas or liquid.

A cell is a device that provides electrical energy to a circuit.

A chain reaction is a self-sustaining sequence of nuclear fission events caused by neutrons released from previous fissions.

A physical change in which a substance transitions between solid, liquid, and gas due to energy transfer, without changing its chemical identity.

A property of matter that causes electric forces; like charges repel and opposite charges attract. The SI unit is the coulomb (C).
