Physics Unit 4 Definitions

Density
Mass per unit volume
1 of 17
Force (in terms of momentum)
Rate of change of momentum
2 of 17
Simple Harmonic Motion
Oscillation where acceleration id directly proportional to the displacement and directly towards the equillibrium
3 of 17
Periodic Force
A force applied at regular intervals
4 of 17
Natural frequency
The frequency of a system's oscillation without a force
5 of 17
Forced oscillation
Oscillation produced when a periodic force is applied
6 of 17
Force between two masses
The force between two masses is attractive and proportional to the product of the masses and inversely proportional to the square of their separation
7 of 17
Magnetic field
The region around a magnetic material or a moving electric charge within which the force of magnetism acts
8 of 17
Magnetic flux density
Magnetic force per unit length per unit current on a current carrying conductor which acts at right angles to the field lines
9 of 17
Faraday's Law
Induced emf is proportional to the rate of change of flux
10 of 17
Flux Linkage
How much flux goes through the coil
11 of 17
Lenz's Law
Direction of the induced emf is such that it resists the charge causing it
12 of 17
Electric fields
Volume where a force acts on a charge due to its charge
13 of 17
Electric field strength
Force per unit charge
14 of 17
Electric potential of a point in space
Work done per unit charge to move a charge to that point from infinity
15 of 17
Capacitance
Charge stored per unit volt
16 of 17
1 Farad
1 coulomb stores for 1 volt across a capacitor

I really enjoyed this crossword, although some of the wording on the 'clues' is rather confusing.

kind regards Oli Phillips
