orbits, tides, phases, eclipses and seasons

Short educational video about orbits and how they effect our lives on Earth.

Late response Video for WatcherAzazel‬‏ but hopefully other people will find it useful.

Giving a shoutout to mspurefiction007, check out her moon phases video below:

If I've made any mistakes let me know, I'll correct it in an annotation.

Awesome video James!

Ok, weird question coming your way;

Do you think we will ever be able to control the rotation or tilt of the Earth? Do you it is at all possible sometime WAY in the future when we're more advanced.

It would be awesome to have summer all year round in Canada. lol

@KelzLife What a question! Yeah I'm sure we could if we really really wanted to but there are probably far easier ways to control the climate.

Newtonian theory which is adequate for this description says that the gravitational force IS PROPORTIONAL ro the product of the masses divided by the distance squared - not as your video has equal to. The more modern theory due to Einstein tells a subtly different story but uses a different idea to explain how gravity works - the distortion of spacetime.

@johncrwarner I'll add an annotation.

@YesIamJames

Thanks - there is a constant of 6.67300 × 10^-11 or G that can be added.

[YesIamJames]

@johncrwarner I don't want to over complicate it. I just made the video to show the basics. If I make another more detailed video about it I'll make sure to include it. I thought the gravitational constant was 6.7428.

Cheers for the reponse :) Al

@MsPureFiction007 Lol thanks for finally watching. I kinda rushed the moon phases bit though.

[zombeepictureshow]

Wow, very informative, I truly enjoyed it.

@YesIamJames

6.673 x 10 raised to the power of minus eleven metres cubed divided by seconds squared and kilograms

the last digit might be inaccurate at it is known to only 1 in 10 000 as opposed to the unlike other constants that have been measured to 1 in 100 000 000 000

@OukaKisa It depends on your location. Try this site.
