Hi Physics lovers! Here is the answer video for Assessment 002Q1.
When you start the movie you can press the small controls to view fullscreen.
Hi physics lovers. Here is the link to download the Higher Physics Assessment 02A.
Hi Physics lovers, here are the answers to the homework problems 1.24 to 1.29
1.24 Displacement = -30.6m so depth = 30.6m
1.25 Displacement = -0.82m so height dropped = 0.82m
1.26 (a) 0m/s
(b) 10m
(c) -14m/s ie 14m/s going down
(d) 2.86s
1.27 (a) From the instant it is released it will be subject to negative acceleration -9.8m/s2 So its velocity will decrease to zero and then increase negatively until it strikes the ground.
(b) Displacement = -32.1m so height = 32.1m
(c) Final velocity = -25.4m/s
1.28 (a) 1.53s
(b) 11.5s
(c) 14.7m
1.29 (a) 6.1s
(b) 183.7m

The distances in space are far too large to be measured in kilometres. It is a bit like marking the road distances in millimetres.
Instead astronomers use the light year. The light year is the distance a beam of light travels in one year.
You can use the fantastic Wolframalpha website to explore the distances in space and on Earth in terms of how quickly a beam of light will take to cover he distance.
All you have to do is type into the box light year. You will find the distance a light year in metres.
Try typing in:
Glasgow to Paris. You can equate the distance in terms of how long it would take light to travel this distance = 2.99milliseconds. So we could say that Paris is about 3 milli-light-seconds from Glasgow.
Try typing in Earth to Mars you`ll find that the distance between Earth and Mars is 9.6 light-minutes.
You can download a special worksheet which you can use with Wolfram Alpha.

Have fun converting distances into lightyears, lightminutes or even lightmilliseconds.

Watch out for the changes in energy. Check out how gravitational potential energy can be changed into kinetic energy.
Go on! Have some fun with physics.
