Physical Science S2 Final Exam Review Game

When you are riding on the bus, your bus driver doesn't appear to be moving. This is due to your…

• Distance

• Displacement

• Frame of reference

Speed is the ratio of the distance an object moves to…

• The amount of time needed to travel the distance

• The direction the object moves

• The displacement of the object

A person drives north 3 blocks, then turns east and drives 3 blocks. The driver then turns south and drives 3 blocks. How could the driver have made the distance shorter while maintaining the same displacement?

• By driving east 3 blocks from the starting point

• By driving north 1 block and east 4 blocks

• By driving west 3 blocks from the starting point

A horizontal line on a speed-time graph means the object is…

• Moving at a constant speed

• At rest

• Speeding up or slowing down

A speed-time graph shows that a car moves at 10 m/s for 10 s. The car’s speed then steadily decreases until it comes to a stop at 30 s. Which of the following describes the slope of the speed-time graph from 10 s to 30 s?

• Linear, horizontal

• Curved, sloping upward

• Linear, sloping downward

From which frame of reference in the picture does the tree appear to be in motion?

• From the building’s frame of reference

• From the airplane’s frame of reference

• From the child’s frame of reference

What is the best unit to use to measure the height of the building?

• Centimeters

• Meters

• Kilometers

Bus A travels 300 m in 12 s. Bus B travels 200 m in 12 s. Both vehicles travel at constant speed. How do the distance-time graphs for these two speeds differ?

• The slope of bus A’s graph would be steeper than bus B’s

• The slope of bus B’s graph would be steeper than bus A’s

• The slopes of the two graphs would be the same.

What is the difference between distance and displacement?

• Distance and displacement mean the exact same thing.

• Distance is how far something travels, displacement is how far the end from where they started, and in what direction.

• Displacement is how long it takes for something to travel a certain distance.

The acceleration due to gravity on the surface of Mars is about one-third the acceleration due to gravity on Earth’s surface. The weight of a space probe on the surface of Mars is about…

• three times greater than its weight on Earth’s surface.

• one-third its weight on Earth’s surface.

• the same as its weight on Earth’s surface.
