Earth got you down? Don’t worry, it’s got us all down — thanks to gravity! In this BrainPOP movie, Tim and Moby teach you all about the ins and outs of gravity. You’ll learn everything from Sir Isaac Newton’s famous apple to Albert Einstein’s theory that massive objects use gravity to “bend” space and time. You’ll also find out about gravity’s effect on tides, humans, and even the earth’s rotation. In addition, Tim and Moby explain the difference between mass and weight, and how the moon’s gravity enables us humans to weigh less on the Moon than they do here on Earth!
