Revision
Hints
- Go
over topics covered in Chapters 13,15 and 12, and booklets
and make notes.
- Go over revision exercises and the questions
in your activity booklet.
- If you have not completed the booklet,
use this for revision.
- Check
the General and Specific Outcomes at the start of each chapter
and ensure that you have achieved these.
- Do
any revision sheets and practice tests - the more you do the
better you will know your work.
Note - the best preparation for
exams is to listen, take notes, and do exercises well in class
and to do your homework regularly and well. You should answer
each homework question as if it is an exam question. Consistent
work throughout the term will help you achieve well and reduce
the amount of study needed at the end of term. It will also
establish good study habits that will pay dividends in Year
11 and 12 and university. |
Chapter
13 - Forces and Motion (and Booklet)
- Be able to define a force. Know the
units for force
- Be able to give examples of contact
and non-contact forces and be able to explain the difference.
- Know the effect a force can have on
an object.
- Be able to define
weight.
- Know that the weight
of an object = mg. Be able to preform simple calculations to
determine the weight of an object if g = 9.8 m/s2.
- Be able to explain why the weight of
an object varies around the earth.
- Be able to explain what is meant by
gravitational force between objects. (Newton's Universal Law of
Gravitation)
- Know the effect of that gravitational
force if the mass of the two objects increases or decreases and
the effect of reducing or increasing the distance between the
objects.
- Be able to explain the difference between
mass and weight.
- Know that if the forces
on an object are balanced than an object is either stationary
or moving with constant velocity. Be able to draw the forces
acting on an object.
- Know that if unbalanced cause a change
in the objects motion. (accelerate, decelerate or change direction)
- Be able to state Newton's Laws of Motion.
- Be able to do problems using Newton's
second law (F=ma).
- Be able to identify which of Newton's
laws apply to particular situations.
- Be able to explain the difference between
inertia and momentum.
- Know that there is a relationship between
the speed of an object, its mass and momentum.
- Be able to compare and contrast distance
and displacement, and speed and velocity.
- Be able to interpret displacement-time and velocity-time graphs.
- Know formulae for
average speed and average velocity, and acceleration and know
the units used for each.
- Be able to do problems using these formulae.
- Be able to convert km/h to m/s.
- Be able to interpret and analyse ticker-timer
tapes.
- Be able to do problems involving falling
objects.
- Beable to apply extension motion formulae to problems.
Chapter
5 - Light and Refraction
- Know how
the speed of light changes in various media.
- Be able
to define refraction.
- Know why
refraction occurs.
- Be able
to use the Laws of Refraction.
- Know what
happens to the speed of light in different transparent media.
- Be able
to predict whether light is travelling from an optically more
dense medium to a less dense medium or the reverse by looking
at the way a light ray is bent.
- Be able
to label and identify - the incident ray, refracted ray, angle
of incidence and angle of refraction.
- Be able
to define total internal Reflection and critical angle.
- Be able
to use a known critical angle to predict what happens as rays
of light travel from an optically more dense media to a less dense.
- Know some
applications of total internal reflection.
- Know the
meaning of the term dispersion. Know the colours of the
spectrum and which colour of light is refracted the least and
the most.
- Be able to
draw ray diagrams for biconcave and biconvex lenses
and to describe the image produced.
- Know which
lens always produces an virtual, upright, and diminished image.
- Know which
lens can be used to produce a magnified image.
- Know some
applications of these mirrors and lenses.
Chapter
12 - Waves
(We will not get the chapter on waves done this term, so it will not be on the exam.)
- Be able to explain what is meant by
a wave.
- Be able to explain the difference between
transverse and longitudinal waves.
- Know the meaning of
the terms crest, trough, amplitude, wavelength, period and frequency.
Be able to label the crest, trough, amplitude and wavelength on
a diagram.
- Be able to explain some characteristics
of water waves - cause, wavefront, refraction, reflection and
diffraction.
- Know that there is a relationship between
the wavelength, velocity and frequency of waves.
- Be able to explain what is meant by
electromagnetic waves.
- Know what is meant by the electromagnetic
spectrum and be able to list the main types of waves from the
low energy radio waves to high-energy gamma rays.
