Going down!
the reason why all objects fall toward earth is because of something called Gravity. Gravity on Earth accelerates all objects at 9.81 m/s^2 until they hit terminal velocity, when the object acceleration becomes 0 due to air resistance, falling at a constant speed. People travel 120 mph during terminal velocity.
Gravity’s affect on objects is different in different places in the universe. the gravity on Jupiter pulls on objects a lot stronger giving them a higher acceleration.
