At the point a the object is moving at a constant speed. Any object moving at a constant speed will fit into the motion at A.
Consider the following situations:
a. A car is moving along a straight road at a constant speed.
b. A car is moving along a straight road while slowing down
c. A car is moving along a straight road while speeding up
d. A hockey puck slides along a smooth (i.e., frictionless) icy surface
e. A hockey puck slides along a rough concrete surface
f. A cockroach is speeding up from rest
g. A rock is thrown horizontally, air resistance is negligible.
h. A rock is thrown horizontally, air resistance is substantial.
i. A rock is dropped vertically; air resistance is negligible
j. A rock is dropped vertically, air resistance is substantial
Which of these situations describe the motion shown in the motion diagram at point A?
