This force is higher on more massive planets and he would weigh more on Jupiter than on Earth. Jon uses a fairground ride to simulate the feeling of lower and higher gravitational forces.

However, new studies have shown that gravity is not constant for the entire planet. Instead, this force ... these small but significant changes to how effects gravity has on Earth.
