Year 10 Physical Science Content Descriptions
Energy conservation in a system can be explained by describing energy transfers and transformations
(ACSSU190)
• recognising that the Law of Conservation of Energy explains that total energy is maintained in energy transfer
and transformation
• recognising that in energy transfer and transformation, a variety of processes can occur, so that the usable
energy is reduced and the system is not 100% efficient
• comparing energy changes in interactions such as car crashes, pendulums, lifting and dropping
• using models to describe how energy is transferred and transformed within systems
The motion of objects can be described and predicted using the laws of physics (ACSSU229)
• gathering data to analyse everyday motions produced by forces, such as measurements of distance and time,
speed, force, mass and acceleration
• recognising that a stationary object, or a moving object with constant motion, has balanced forces acting on it
• using Newton’s Second Law to predict how a force affects the movement of an object
• recognising and applying Newton’s Third Law to describe the effect of interactions between two objects

Content
Non-contact forces – gravity, electrostatic and
magnetic
Contact forces – mechanical (push, pull, etc.),
friction, tension, air resistance (drag), support /
reaction force, buoyancy
Explain the concepts compression and tension.
Relate these to Newton’s third law of motion (brief
explanation as Newton’s Laws will be covered in
more details later in the term).
Activities
Explain how the position of the centre of mass and
the width of the base affect the stability of an
object.
Relate this to building design.
Explain how advances in science and engineering
have meant taller and safer buildings, but also
older buildings like the Learning Tower of Pisa can
be saved.
Assessment
& Homework
Brainstorm types of force.
Diagrams showing everyday
situations where these forces
are evident.
Investigating Column Shapes,
Investigating Column Diameter
Loads on Bridge Columns,
Material Testing,
Discuss the properties of various materials that are
used to build structures and relate the material
properties to the job the materials have to do.
Define stress and discuss its effect on different
building materials.
Define strain and relate its importance to materials
(could also include the concepts of ‘creep &
fatigue’).
Resources and Experiments
Hooke’s Law experiment determination of the spring
constant for a stretched spring.
Do elastic bands obey Hooke’s
Law? Could they be used in
force- meters?
Could extend by determining
the energy stored by the spring

Energy and
work done
Mechanical
Energy
Types of energy – mechanical (kinetic and potential
– gravitational, elastic and magnetic), chemical,
electrical, heat, light, sound and nuclear.
Work done = Force x distance moved – linking
together the concepts of force and energy
Efficiency (%) = useful output energy / total
input energy x 100
Introduce equations for calculating both kinetic and
gravitational potential energy:
kinetic energy = ½ x mass x speed2
and
gravitational potential energy =
mass x gravitational field strength x height
Brainstorm types of energy.
Diagrams showing everyday
situations where these types of
energy are evident.

Investigation and Validation Test
Define and discuss scalar and vector quantities,
using distance and displacement as examples.
Introduce speed as a scalar quantity and velocity
as a vector quantity. Define: speed = distance ÷
time and
velocity = displacement ÷ time Simple examples
to emphasise the difference between them.
Reinforce the idea that 2 plus 2 does not always
equal 4!
State and explain Newton’s three laws of motion.
Apply the second law to safety design features
associated with most motor vehicles – air bags,
crumple zones, seatbelts, etc. Qualitative treatment
only.
