How does moving horizontally prevent satellites from falling towards earth?

2.73K views

If I was on a satellite, and I pushed an apple towards earth, would it stop falling and level out?

And if I was on a satellite and pushed an apple in the opposite direction at the same speed I was travelling
(net speed = 0), would it start falling towards earth?

A bit like how swinging an unwound yoyo round lets it travel in a big circle rather than just falling down. It’s got sideways momentum and a constant force which makes it go in a circle (the tension in the string doing the same job as gravity on the satellite).
