Acceleration & Speed/ Roller Coaster Engineers

Which word means the steepness of a line?

• acceleration

• slope

• speed

• horizontal

Which word describes a line going up and down?

• horizontal

• vertical

• slope

• velocity

What is the difference between instantaneous speed and average speed?

• Instantaneous speed is the speed at one moment where as average speed is the average of the speed over a length of time.

• Instantaneous speed is the average of the speed over a length of time where as average speed is the speed at one moment.

• Cheetahs have instantaneous speed, but cars have average speed.

• Instantaneous speed is quite a bit faster than average speed.

Which word describes a line that goes from side to side?

• horizontal

• vertical

• east to west

• velocity

What is the definition of velocity?

• distance/time

• the speed of an object at one instant of time

• data arranged in rows and columns

• the speed and direction of an object

What is g-force?

• a drawing using a series of dots, lines, or pieces to show data

• the force of acceleration in relation to gravity

• a scare factor for your entire body

• going from zero to max speed

What are the two ways to accelerate? (Choose two)

• changing weight

• changing speed

• changing direction

• changing velocity

How do roller coaster engineers create rides that make people feel the speed? (Choose two)

• loops and rolls that change direction quickly

• they use lap bars and brakes

• a tall first hill that allows the ride to pick up speed

• they plan for lots of positive g-force

What is the difference between a table and a graph?

• A table uses dots, lines, or pieces to create a visual representation of data. A graph just shows data in rows and columns.

• A table gives a visual representation of data; a graph has rows and columns of data.

• A table is a place you eat dinner, and a graph is something they do when you burn your skin.

• A table only has data in rows and columns; a graph gives a visual representation of data.

Why did the first roller coaster make people sick?

• The g-forces were too high and some people blacked out.

• The g-forces were too low and people felt too weightless.

• The engineers did not design adequate safety features for people's heads.

• The engineers did not design a lap belt, and people fell out.
