IB Physics HL
Fundamental SI units - correct answer ✔kilogram (kg), metre (m), second
(s), ampere (amp), mole (mol), kelvin (K)


Random error - correct answer ✔An unpredictable and largely uncontrollable
uncertainty. (Examples include human reaction time and other forms of
human measurement.) (Random errors can be reduced by taking the average
of repeated measurements.)


Systematic error - correct answer ✔An error that occurs on all
measurements. (An example is a zero error on a scale.) (Systematic errors
can NOT be reduced by repeated measurement.)


Vectors - correct answer ✔displacement, velocity, acceleration, force,
momentum.


Scalars - correct answer ✔mass, length, speed, energy, time.


Displacement - correct answer ✔the position of an object relative to a
defined starting position


Velocity - correct answer ✔the rate at which displacement changes (with
time)


Speed - correct answer ✔the rate at which distance changes (with time)


Acceleration - correct answer ✔the rate at which velocity changes (with time)

, Instantaneous speed - correct answer ✔the speed at a particular moment in
time


Average speed - correct answer ✔the total distance travelled divided by the
total time taken (the average rate of movement)


Equations of uniformly accelerated motion - correct answer ✔v = u + at
s = ½(u+v)t
s = ut + ½ at²
v² = u² + 2as


Newton's First Law - correct answer ✔A body will continue in its current state
of motion (velocity) unless acted upon by a resultant force
(a = 0 if ∑F = 0)


Newton's Second Law - correct answer ✔The acceleration of a body is
proportional to the resultant force acting on the body (and is in the same
direction)
∑F=ma ∑F= Δp/Δt


Newton's Third Law - correct answer ✔When two bodies interact, the force
that body 1 exerts on body 2 is equal and opposite to the force that 2 exerts
on 1
(F ₁₂= -F ₂₁)


Inertial mass - correct answer ✔The mass of a body as determined by the
second law of motion from the acceleration of the body when it is subjected to
a force that is not due to gravity. (The measurement of an object's resistance
to changes of motion)
