A student observes
an object moving. A
graph of the
movement is
shown.

The object moves forward in a arc that
extends to the left of the observer at a
faster rate.
The object accelerates away from the
observer from left to right before coming
to a complete stop.
The object starts behind the observer
and moves past the observer before
returning to the starting point.
The object moves with a constant
velocity in the negative direction then
the positive direction then negative
again.
Which best
describes the
motion depicted on

To avoid a time delay, the larger jet
refuels the smaller jet.
What must the speed of the two jets be
relative to the ground?
1. The smaller jet must be
faster to align with the
fuelling jet.
2. The fuelling jet must be
faster to avoid spilling.
3. The speed must change
depending on altitude.
4. The speed must be the
same for both jets.

An observer is watching a passenger moving on a

that the sidewalk is moving at 5 km/h yet the
passenger appears to be moving at 12 km/h. Which
would best explain what the observer sees?

The passenger is moving 7 km/h
in the same direction of the
sidewalk.
The passenger is moving 5 km/h
in the same direction of the
sidewalk.
The passenger is moving 7 km/h
in the opposite direction of the
sidewalk.
The passenger is moving 12
km/h in the opposite direction of
the sidewalk.

A book is lying on a seat in a car that is moving at 50 kilometers per hour
(km/h). The driver says that the book is not moving. An outside observer
says the book is moving at 50 km/h because it is in the car. Which is the
most logical conclusion for these two statements?
1.
2.
3.
4.
Motion is detected only if the car
accelerates and is measured by the
observer.
Motion is absolute, and the driver is
incorrect saying that the book has
no motion.
Motion is relative to a given frame
of reference, and both the driver
and observer are correct.
Motion is constantly changing so
neither person’s statement will be
correct when the car slows down.

The current of a river is
flowing south at a speed of
10 kilometers per hour
(km/hr). The speedometer
on a motorboat moving
north indicates the speed of
the boat to be 14 km/hr. A
person is traveling north on a
bicycle along the riverbank.

rider travel so the boat and
bicycle appear to be moving
at the same speed to an
observer on the shore?
