![]() ![]() This does include its mass, the surface area and how fast it is moving. This is because gravity is not the only force acting on the falling object, air resistance is also a factor and that does depend on quite a few properties of the object and the fluid it is falling in. This fact has been demonstrated many times, even on the moon with a feather and a hammer.īack on our air-filled planet, if a feather and a ball are dropped from the same height they clearly do fall at different rates. This happens because the acceleration due to gravity is the same for both objects and that actually this acceleration has nothing to do with the mass of an object. His most famous observation was that two objects of the same size but slightly different mass (how much “stuff” it is made of) hit the ground at the same time, as far as he could tell, if they are dropped from the same height. Galileo was a famous scientist in the 16th and 17th Century. ![]() Great Gravity Experiments for Kids Galileo and Gravity This article from ScienceAlert tells you how high you could jump on each planet in the Solar System compared to Earth. Gravity also holds Earth and the other planets in their orbits around the Sun.ĭid you know – gravity exists on the Moon but it is not as strong as on Earth, which is why astronauts can jump higher on the Moon than on Earth. It’s the reason we walk on the ground rather than float around. Gravity is the force that pulls objects towards the Earth. If you enjoy them, do check our my book This IS Rocket Sciencewhich is full of exciting space activities demonstrating how rockets overcome gravity and other forces to launch into space followed by a tour of the solar system with an activity for each planet. You can enable all levels with the press of a button, for one thing, but I really like the Mini Mode, which scales levels right down and lets my tinker away from the comfort of my chair.These gravity experiments are all fantastic demonstrations of gravity and a great way to learn about Isaac Newton and Galileo‘s famous discoveries. But, on the flip side, you’ll get a genuine jolt of pride when you sit back, press play and watch your mad little invention start to tick away.Įxtra points go to some of the game’s special options too. The game requires such a specific degree of fine-tuning - from the angles of launchers to the gradients of ramps - that things can get finicky quickly. It isn’t long before Gravity Lab becomes a much more taxing experience, introducing more complex pieces, like gates that will trigger different actions or laser nets that block progress. But each of the 30 puzzles comes fitted with three difficulties, restricting the resources at your command, turning Gravity Lab from a breezy piece of experimentation into something a little more fiendish. Many of the starting levels can be overcome with brute force, compiling an embarrassing number of ramps, hastily stickered all over the room to avoid any mistakes. Assembling levels piece-by-piece, watching your creation steadily evolve and take shape carries mad scientist satisfaction, and seeing it all play out in a 3D space captures simple VR thrills. It’s Lemmings by way of a physics class – you might say, fire orbs halfway across a room, where they’ll land on floating ramps that peddle them in a specific direction, down through a gate to invert their gravity, then watch them float into the goal zone. In each level, you have one machine that fires out orbs and various platforms and gadgets to help taxi a certain number of them to their destination. Set on an off-planet gravity testing lab, you need to carry out a highly scientific test – get balls in buckets. Gravity Lab starts off as simple as they come. ![]()
