Unit 3 & 4 Physics Definitions

A measurement of the total magnetic field that passes through a given area

A difference in potential that tends to give rise to an electric current

States that the direction of an induced electric current always opposes the change in the magnetic field

The capacity of electric charge carriers to do work due to their position in an electric circuit

The intensity of an electric field at a particular location

Which of the following is NOT a quark?

Which of the following is NOT a lepton?

Radiant energy consisting of synchronised oscillations of electric and magnetic fields

The time interval measured in the frame of reference in which the object is at rest

The time taken to complete one revolution

The length measured in the frame of reference in which the object is in motion

The minimum energy required to remove an electron from a solid

The force acting on an object travelling in a circle

Composite subatomic particles made up of three quarks

A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time

The difference of elapsed time between two events as measured by observers moving relative to each other

Which of the following is NOT a boson?

Subatomic particles composed of one quark and one antiquark

All planets move about the Sun in elliptical orbits, having the Sun as one of the foci

Any frame of reference with respect to which the acceleration of the object of observation remains zero

A region of space near a magnet, electric current or moving electrically charged particle in which a magnetic force acts
