PHYSICS JAN EXAM Flashcards
Newton is
The force which when applied to a unit mass produces unit acceleration
Farad
value of capacitance that a capacitor has if it stores unit charge per unit pd
applied
State the Law of Conservation of Energy
Energy cannot be created or destroyed but will change into other forms of energy
Define capacitance
amount of charge stored on a capacitors
Newton’s Second Law of Motion
external force is applied to a body its acceleration is proportional to the
force applied and inversely proportional to the body’s mass
Newton’s First Law of Motion
body will remain stationary or will move in a straight line at uniform velocity unless
an external force acts
Newton’s Third Law of Motion
For every action there is an equal and opposite reaction
coulomb
amount of charge that flows past a point when unit current flows for unit time
volt
pd applied when unit energy is transferred per unit charge
emf
energy transferred by a power source per unit charge that flows from it
Boyle’s Law
product of a gases pressure and volume is constant provided that the
temperature remains constant
joule
power of a system that transfers unit work in unit time
power
work transferred per unit time
density
Mass per unit volume
Define Young’s Modulus
stress to strain ratio for the linear section of a stress/strain curve
