The escape velocity is the minimum speed needed to overcome the effects of this force.
When air resistance exactly counteracts this force, an object has reached terminal velocity. The escape velocity is the minimum speed needed to overcome the effects of this force. On Earth, this force acts to accelerate a body at nine point eight meters per second squared. For 10 points, name this force responsible for keeping objects on the ground.
