The Wondrous Physics of Motion

How to set great scientific guesses, also known as hypotheses? Let's practise using a handful of scenarios.

Stuff in space

See all objects that mankind has sent to space and still can be detected using radio signals.

Scale of the universe

Try it yourself.

Quantifying measurements

Covers study notes on physics as a field of science and on the basics of the SI system.

Experiment: Rolling on a tilted surface

Equipment:

a ball
2 wooden blocks
a timer

Instructions:

Raise one end of your table with your blocks.
Let a ball roll from the elevated end. Measure with a timer.
Which variables increase or decrease the time taken?
Form a model.

[[$$ a = \frac{F}{m} = \frac{mg \sin \alpha}{m} = g \sin \alpha = \frac{gh}{L} $$]]
[[$$ s = \frac{1}{2}at^2 \Leftrightarrow t = \sqrt{\frac{2s}{a}} $$]]
[[$$ t = \sqrt{\frac{2L}{a}} = \sqrt{\frac{2L^2}{gh}} = L \sqrt{\frac{2}{gh}} $$]]

Welcome!
