How Does ‘Gravity’ Affect the Way We Move on Earth and in Space?

Gravity is like an invisible hand that pulls everything toward the ground. On Earth, it helps us walk and jump, but in space, astronauts float because there’s less gravity pulling them down. Imagine being on a giant trampoline, when you're close to the center (like on Earth), you feel strong pull; when you go far away (like in space), it feels much lighter.
