Motion detector graphs, distance vs time

[moomoocow]

hi!
a ball is dropped from a height of 1 meter above the floor. Take the origin to be the point from which the ball is released.
would the graph be like a curved graph rising to the right starting from the origin?

how would the graph look like if a car is parked on a steep hill?

thank you

As time progresses the downwards speed of the ball (and the car) increases. If the speed of an object increases it covers more distance in the same time. This implies that the object covers more distance in the same time interval at a later time in its motion. How should the distance - time graph have to look then? Will a straight upwards sloping graph do?
