An object falls freely from rest in a vacuum. The graph shows the variation with time t of the velocity v of the object. [graph of v against t showing a straight line through the origin] Which graph, using the same scales, represents the object falling in air?

1. Agraph A: straight line through origin
2. Bgraph B: curve with decreasing gradient reaching terminal velocity
3. Cgraph C: curve with decreasing gradient
4. Dgraph D: curve with increasing gradient
