3.2 Chemical and material behaviour
the particle model provides explanations for the
different physical properties and behaviour of matter
●
Particles Sc3 (1) (2)
how the particle theory of matter can be used to explain the properties
of solids, liquids and gases, including changes of state, gas pressure and
diffusion
●
that when physical changes take place (e.g. changes of state, formation
of solutions), mass is conserved

to relate changes of state to energy transfers

3.1 Energy, electricity and forces
forces are interactions between objects and can affect
their shape and motion (this includes pressure effects,
linear motion and turning moments)
●
Forces Sc4 (2)
● how to determine the speed of a moving object and to use the
quantitative relationship between speed, distance and time that the
weight of an object on Earth is the result of its gravitational attraction
between its mass and that of the Earth
The National Strategies | Secondary
Effective demonstrations
that unbalanced forces change the speed or direction of movement of
objects and that balanced forces produce no change in the movement
of an object
●
ways in which frictional forces, including air resistance, affect motion
●
that forces can cause objects to turn about a pivot
●
the principle of moments and its application to situations involving one
pivot
●
the quantitative relationship between force, air and pressure and its
application (e.g. use of skis and snowboards, the effect of sharp blades,
hydraulic brakes)
