Can We Help?: Effects of g-force on the human body

Peter Rowsthorn visits the Australian International Air Show to answer the question, 'What effect does g-force have on the human body?' Join Pete in the cockpit of a light plane for some aerobatics with pilot David Pilkington. G-force expert Dr David Newman explains the science as Pete endures up to 6 g in the aircraft.

Falling for Gravity

This activity invites students to calculate the acceleration of gravity using simple materials, a cell phone, and a computer to record, watch, and analyze the motion of a dropped object. The activity includes a list of tools and materials required, assembly instructions, what to do and notice, an explanation for the underlying ...

Forces and Motion: Basics

This interactive simulation explores speed, acceleration and unbalanced forces in a simple system. In a series of simulations students identify when forces are balanced vs unbalanced; determine the net force on an object with more than one force acting on it; and predict the motion of an object with zero net force or given ...

Mexican jumping bean | Questacon

In this activity, students investigate Newton's laws of motion and inertia by experimenting with the movement of a marble in a short cylinder (or 'bean'). The activity includes a list of what is required, suggestions of what to do and notice, questions to ask, an explanation for the underlying science of what students observe ...
