A 90 minute exploration of forces, pressure and some of the strange thoughts people have had about them through the ages. We will cover impact forces, forces applied over a distance, acceleration, movement and inertia, as well as getting a historical overview of the subject and some of the key figures in the development of our understanding of forces. We will also explore free-fall with a ball on a string and a leaky cup, and finish off with surface pressure concepts with a bed of nails and a volunteer.

Australian Curriculum

This program was designed to support:



Year 7

Year 8

Physical Sciences

Change to an object’s motion is caused by unbalanced forces acting on the object (ACSSU117)

Earth’s gravity pulls objects towards the centre of the Earth (ACSSU118)

Energy appears in different forms including movement (kinetic energy), heat and potential energy, and causes change within systems (ACSSU155)


Year 10



The motion of objects can be described and predicted using the laws of physics (ACSSU229)
