How gravity speeds a falling ball
Teaching this? Open projector mode
In this ideal model, an object in free fall near Earth accelerates downward at g ≈ 9.8 m/s²: we neglect air resistance and changes in gravity with height. Released from rest, it gains another 9.8 m/s of downward speed each second.
Check yourself
A ball is dropped from rest. After 1 second, roughly how fast is it moving?
