IB Syllabus Structure
What does the abbreviation IA stand for?
Internal Assessment
Define the displacement of an object.
The change in position of the object.
What is the unit of acceleration?
meter per second squared/meter per second per second
What are the magnitute (to one decimal place) and the direction of acceleration due to gravity near the Earth surface in Australia?
9.8 m/s^2 downward.
What is the unit for measuring work?
Joules.
What's topic A1 about?
Kinematics
How can instantaneous velocity be deduced from a dispacelement time graph?
Draw a tangent at the point of interest and work out its gradient.
What must be directions of velocity and acceleration if an object is slowing down?
Opposite
When may the acceleration due to gravity considered constant?
When objects fall near the surface of a planet (or other body).
What's the other name for heat energy?
Thermal energy.
What type of questions does Paper 1A have?
Muliple choice.
What does the area under a distance-time graph represent?
Nothing/No meaningful physical quantity in IB Physics
When can an object moving at constant speed have a non-zero acceleration?
When its velocity changes direction.
If there is no air resistance and the total displacement of an object thrown upwards is zero, how are the magnitude and the direction of the final velocity related to those of the initial velocity?
The final velocity has the same magnitude and opposite direction.
What particles are found in the nucleus of an atom?
Protons and neutrons.
Which month the first exam (Paper 1A and 1B) will be in 2027?
April
Under what condition can the equation v2=u2+2as be used?
Uniform/ constant acceleration
What is the difference between these two types of acceleration: a=v2/r and a=Δv/Δt?
1st one is centripetal and the 2nd is tangential.
If two objects whose masses are 1 g and 10 kg are released from the same height on the Moon, which will touch the ground earlier?
Both will fall at the same time.
How old is the Universe in, years?
About 14 billion.
Your final IB physics grade will be weighted at ______% external assessment and ________% internal assessment.
80 and 20
What is kinematics?
The study of motion without considering its causes.
An object is moving at 10 m/s for 20 m/s and then 20 m/s for one-third of a minute. What is the object's average velocity over the entire time?
15 m/s.
A monkey is jumping horizontaly from a tree with the initial velocity of 5 m/s. A banana starts falling from the tree at the same time. What will be first on the ground? Air resistance may be neglected.
Both will fall at the same time.
What triggered 'The Big Bang' that created the Universe?
This is not known (with evidence).
