On Earth, Maurice can just make it over the 5 ft high bar. With the same speed and launch angle, can he clear the bar on different planets? Click on a planet to see if he can.
Venus is a bit smaller than Earth and closer to the Sun. Its surface is hot enough to melt lead! Its surface gravity is 90% of Earth or 0.9g. Maurice weighs 90 lbs here; you would feel just a bit lighter than normal – but very hot!
The change in gravity isn't much and the results are close to what you would see on Earth. Maurice jumps 5.5 feet (1.68 meters) on Venus – just 6 inches higher than Earth-normal. He is in the air for just 0.6 seconds.
Here on Earth we fall at 9.81 m/s2 (meters per second squared) – we call that One 'g'. Maurice weighs 100 lbs here on Earth – we will compare his weight on other planets in our solar system as you jump there!
Maurice jumps off the ground with a vertical speed of 5.5 meters per second – this has to do with his strength and mass – NOT the local gravity – in our demonstration, it never changes! Maurice jumps 5 feet high on Earth (1.52 meters); this is a typical height for a JV high-jumper on Earth.
The Moon is four times smaller, and has just 1% of Earth's mass; this makes its local gravity much lighter, just 1.62 m/s2 or 0.16 g. Maurice weighs just 16.5 lbs here, but he is as strong as ever. This means that you could jump much higher and stay in the air longer if you were jumping on the Moon!
Jumping off the ground at the usual 5.5 meters per second, Maurice's high jump rises to 30.0 feet (9.2 m), as tall as a three-story building! The massive jump also keeps you in the air longer, almost 6.8 seconds – six times more air time than on Earth!
Mars is half the size of Earth, but only 10% as massive; local gravity is 3.74 m/s2 or 0.38 g. Maurice weighs 38.1 lbs here. With local gravity about 1/3 of Earth, Maurice should jump three times higher!
Thin atmosphere and low gravity make Mars a great place for sports! Maurice can jump 13.1 feet (4.0 meters!); high enough to leap onto the roof of a typical one-story house.
Jupiter is the giant of our solar system, it takes 320 Earths to make one Jupiter! Jupiter is a gas planet and has no solid surface – the 2.7 g local gravity is what you would feel if you were flying in an airplane among the cloud tops here. Maurice weighs 270 lbs here on Jupiter!
Maurice can jump only 1.8 feet (0.56 m) here! The high gravity makes it difficult to walk, much less jump. A trip and fall in this gravity would mean serious injuries!
Neptune is a gas planet similar to Jupiter, it has no solid surface. Surface gravity near the cloud tops is very similar to Earth at 1.16 g. Maurice weighs 116 lbs here and feels nearly Earth-normal.
Maurice's jump on Neptune carries him 4.3 feet high (1.31 meters), almost as high as he would go on Earth. At this height, he stays in the air just under 1 second.
Pluto-Charon is a binary planet probably split in half by a giant collision billions of years ago. Local gravity on this tiny world is just 0.065 g – a pencil rolling off a desk takes 2 seconds to hit the floor! Maurice weighs just 6.5 lbs here – about the same as a newborn child!
Maurice jumps a towering 77 feet on Pluto (23.5 m). This jump would carry him over a seven-story office building with ease. Maurice would also have time to enjoy the view, he would be in the air for over 17 seconds!
