Air Resistance Force
... (gain speed) because there is no force big enough to balance the downward force of gravity. • As an object gains speed, it encounters an increasing amount of upward air resistance force. • objects will continue to accelerate (gain speed) until the air resistance force increases to a large enough val ...

Newton`s First Law - Inertia
... The planets would move in straight lines at constant speed (velocity) No, we don’t know the reason why objects persist in their motion when nothing acts on them, but we call this property inertia. We understand many things – but some things – gravity and inertia for example, are still unexplained. ...
