P1.1. Energy Transfer
Energy can be transferredfrom one place to another by work or by heating processes. We need
to know how this energy is transferred and which heating processes are most important in a
particular situation.

P1.1.1. Infrared Radiation
Allobjects emit and absorb infrared radiation
.…

E is energy transferred in joules, J
m is mass in kilograms, kg
is temperature change in degrees Celsius, °C
c is specific heat capacity in J / kg °C


P1.2. Energy and Efficiency
Appliances transfer energy but they rarely transfer allof the energy to the place we want. We…

In some power stations an energy source is used to heat water . The steam produced drives a
turbine that is coupled to an electrical generator .
Energy sources include:
The fossil fuels (coal, oil and gas) which are burned to heat water or air
Uranium
and plutonium , when…

Waves can be reflected, refracted and diffracted . Significant diffraction only occurs when the
wavelength of the wave is of the same order of magnitude as the size of the gap or obstacle .
Waves undergo a change of directionwhen they are refracted at an interface . Waves are not…

P2.1. Forces and Their Effects
Forces can cause changes to the shape or motion of an object. Objects can move in a straight line
at a constant speed. They can also change their speed and/or…

decelerate ). Graphs can help us to describe the movement of an object. These may be
distance-time graphs or velocity-time graphs.

P2.1.1. Resultant Forces
Whenever two objects interact, the forces they exert on each other are equal and opposite .
A number of forces acting at a point may be…

A vehicle's braking distance can be affected by adverse road and weather conditions and poor
condition of the vehicle. Adverse road conditions' includes wet or icy conditions. Poor condition
of the car is limited to the car's brakes or tyres.

P2.1.4. Forces and Terminal Velocity
The faster an object moves…

Gravitational potential energy is the energy that an object has by virtue of its positionin a
gravitational field .
Ep = m x g x h
Ep is the change in gravitational potential energy in joules, J
m is the mass in kilograms, kg
g is the gravitational field strength…

t is the time in seconds, s
The potential difference (voltage) between two points in an electric circuitis the work done
(energy transferred ) per coulomb of charge that passes between the points.
V = W/Q
V is the potential difference in volts, V
W is the work done in…

The current through a component depends
on its resistance . The greater the resistance the
smaller the current for a given potential difference across the component.
The potential difference provided by cells connected in series is the sum of the potential
difference of each cell (depending on the direction in…
