![]() ![]() So, next time you’re kicking a football around in the park, you’ll know how gravity is bringing the football back down to Earth. This is because although the sun is much bigger than the moon, it is much, much further away – and the pull of gravity gets weaker the bigger the distance between objects. We know that the sun is much bigger than the moon – so surely it ought to be able to pull water towards it? Actually, it does – but much less than the moon. Then the tide goes out, and the water level drops, as the moon rotates around the Earth.Īn interesting question is why we don’t have enormous tides caused by the sun pulling on the Earth. As the water level rises, it is being pulled towards the moon, and the tide comes in. Unlike the football, the moon is heavy enough to have an effect – just a little one, because the Earth is still much heavier – but it’s enough for us to notice when we watch the tides. This is also an effect of gravity, and it happens because the moon is close to the Earth. And as as the sea level drops down, the water gets further away from you. As the sea level rises, the water gets closer to you, because the beach you are sitting on slopes upwards away from the sea. But the sea is not actually moving in and out – it is moving up and down. After some time, the sea seems to get further away – now, the tide is going out. Sitting on the beach, you can see the sea gradually getting closer and closer to you – this is the tide coming in. On the moon, you seem to weigh less than on Earth, so you can jump higher. This is because the Earth is bigger than the moon, so the force between you and the Earth – which is what we call weight – is bigger than the force between you and the moon. ![]() If you jump on the moon, you’ll be able to go much higher than you can on Earth. It is related to how heavy – or how massive – an object is. When we arrive on the moon, you’ll see that the pull of gravity is not the same everywhere. NASA's Marshall Space Flight Center/Flickr., CC BY-NC The answer is that the planets are all moving, and the balance between the force of gravity and the speed of their movement (which comes from when they were first made, about 4.5 billion years ago) keeps them circling round the sun.įly me to the moon. You might be wondering why the Earth (and all the other planets) don’t just fall into the sun, the same way the football falls to Earth. Now, the sun is much, much bigger than the Earth, which means its pull is very powerful indeed. Our next stop is the moon, and as we journey up into space, there’s a good chance you’ll see the sun. The thing is, the Earth is very heavy – much heavier than the football – so it’s unaffected by the pull of the football, while the football itself is pulled back down to Earth. But that’s not the only thing that’s happening: the gravity of the football is also pulling on the Earth. When you kick the football into the air, the Earth’s gravity pulls it back down. To see how gravity works in our universe, we’re going to take a journey, with a few stops along the way.įirst off, we’ll go to the park and play a game of football. The Chainsmokers feat.After lots of experiments, and some very clever thinking, he worked out that the force of gravity depends on how heavy objects are, and that the pull of gravity between objects gets smaller, the further apart they are. The characters clearly have a very passionate relationship and it's on full view throught the majority of this visual.īut we're not complaining and if anything, it's kinda made us ship Drew and Halsey a bit.just saying. Whilst the title of the track is obviously 'Closer', we weren't quite ready for just how close these two would get in the video. ![]() Thankfully the music video that accompanies it is also thoroughly enjoyable, which makes us love the song even more!Īs we all know, The Chainsmokers' Drew provides the vocals for the track alongside Halsey and both star in the pretty racey video. ![]()
