Mechanics

Terminal Velocity= When two opposite forces are equal and opposite. 

Air resistance decreases the speed/velocity of an object. As the speed increases, the air resistance also increases and the object accelerates at a lower rate.

Graphing motion:

Difference between displacement-time graphs and distance-time graphs:

Displacement is a vector quantity and the graph will therefore include negative data if the object is moving in the opposite direction from where it started.
