Background
Why
do parachutes slow a fall? What is weightlessness? What is the best way to win
at tug-of-war?
What
do bungee jumping, using seat belts, and skiing have in common?
Suggestions
for you to try out.
Why
are crumpled cars safer cars? Why does a little go a long way when you are in
space? And why are friends useful if the car breaks down?
Try
out some experiments on forces - if you know the rules it is easier to achieve
what you want.
How
might better control of forces make cars safer and games more successful?
Suggestions
for you to try out.
What
makes fireworks go with a bang? Are things always equal? And why, in space,
it's not easy to be "pushy"?
From
snooker to car crashes, the rules are the same.
Why
does every action have a reaction?
Suggestions
for you to try out.
What
is the connection between a simple playground roundabout and the latest thrill
rides?
What
are the forces on objects travelling in a circle and what alters the forces?
What
does it take to go round a corner rather than go in a straight line?
Suggestions
for you to try out.
What
happens when we "force" things?
What
happens when things rub together?
Why
are we all attracted to each other?
What
exactly is speed?
What
exactly is acceleration?
Because
it's inertia there's no experiment here - but lots to think about.
Every
single minute of every single day we are using forces and experiencing their
effects on us and the world around us. Sitting, walking, playing, travelling
- all involve forces being used to achieve objectives. And, although we may
not always realise it, there are relationships between those forces and the
movements they cause. So this is your chance to look at some of those forces
and movements and explore how the world works.
Sometimes
it is easy to see the laws of physics when experiments are done in zero gravity.
