The graph shows the velocity of two different cars during a period of ten seconds. During

which time interval is the acceleration of Car 1 equal to

zero relative to Car 2.

A student observes an object moving. A

graph of the movement is

shown.

Which best describes the

motion depicted on the graph?

1. The object moves forward in a arc that extends to the left of the observer at a faster rate.

2. The object accelerates away from the observer from left to right before coming to a complete stop.

3. The object starts behind the observer and moves past the observer before returning to the starting point.

4. The object moves with a constant velocity in the negative direction then the positive direction then negative again.

Car 1 is moving north at 100 kilometers per hour (km/hr). Car 2

passes Car 1 by moving at 110 km/hr in the same direction.

From the frame of reference of the driver in Car 1, how fast is Car 2

going?

A boat travels north at a rate of 25 kilometers per hour (km/h) relative to the current of the river. The current of the river

moves south at a rate of 10 km/h relative to the ground. What is the rate of motion of the boat relative to the ground?

A plane is flying east at a velocity of 350 km/hr. A

passenger on the plane walks towards the rear of

the plane at 3 km/hr.

What is the passenger’s velocity relative to the captain who is flying

the plane?

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 2 3 4

0% 0%0%0%

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 moving sidewalk at the airport. The observer knows

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?

1. The passenger is moving 7 km/h in the same direction of the sidewalk.

2. The passenger is moving 5 km/h in the same direction of the sidewalk.

3. The passenger is moving 7 km/h in the opposite direction of the sidewalk.

4. 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

0% 0%0%0%

1. Motion is detected only if the car accelerates and is measured by the observer.

2. Motion is absolute, and the driver is incorrect saying that the book has no motion.

3. Motion is relative to a given frame of reference, and both the driver and observer are correct.

4. Motion is constantly changing so neither person’s statement will be correct when the car slows down.

A train is moving south at 120 kilometers per hour (km/hr). Javier is

walking at 5 km/hr relative to the train. Kassandra is moving toward the back of

the train at 7 km/hr.

A bus is moving east at a velocity of 100 km/hr. A

passenger on the bus walks towards the front of the bus at

7 km/hr. A police officer is standing on the sidewalk as the

bus passes.

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.

How fast must the bicycle rider travel so the boat and bicycle appear to be moving

at the same speed to an observer on the shore?
