P3.2.3 –
Specification
Title:
Hydraulics
a) Liquids are virtually incompressible, and the pressure in a liquid
is transmitted equally in all directions.
b) The use of different cross-sectional areas on the effort and load
side of a hydraulic system enables the system to be used as a
force multiplier.

Title:
Circular
Motion
Text book
Collins further
pages 158-159
Lesson objective; Lesson outcomes
Specification
a) When an object moves in a circle it continuously accelerates
towards the centre of the circle.
This acceleration changes the direction of motion of the body, not
its speed.
b) The resultant force causing this acceleration is called the
centripetal force and is always directed towards the centre of the
circle.
Objective: Be able to describe what causes circular motion and
the factors that affect it.
