Match Units

100

Km are a measurement of this type of quantity.

What is a distance?

200

Min are a measurement of this type of quantity.

What is time?

300

m/s is a measurement of this type of quantity.

What is speed or velocity?

400

km/hr/s is a measurement of this type of quantity.

What is acceleration?

500

When a question asks, "What is the acceleration of an object that changed its speed from # mi/hr to #mi/hr in # sec. , this would be the unit label to go with the answer.  (Don't worry about the math - just the unit.)

What is mi/hr/s?

Acceleration Easy

100

v₂ = 4 m/s

v₁ = 1 m/s

t = 3 s

This is acceleration.

What is 1 m/s/s ?

200

v₂ = 45 m/s

v₁ = 0 m/s

t = 9 sec.

This is acceleration.

What is 5 m/s/s?

300

v₂ = 30 m/s

v₁ = 50 m/s

t = 10 sec.

This is acceleration.

What is -2 m/s/s?

(MUST have negative sign!)

400

t = 8 s

V₁ = 20 mi/hr

v₂ = 40 mi/hr

This is acceleration.

What is 2.5 mi/hr/s?

500

V_{1 =} "rest"

v₂ = 65 km/hr

t = 10 sec

What is 6.5 km/hr/s?

Acceleration Harder

100

This is what it means to have a negative acceleration value.

The object is slowing down.

200

This is what it means to say an object has an acceleration of 3 mi/hr/s.

(For every second . . .)

What is . . .

For every second, the object increases its speed by 3 mi/hr.

300

If an object has an acceleration of 5 m/s/s, this will be its speed after 5 seconds.  (You could make a chart for this.)

What is 25 m/s?

T= 0 s V= 0 m/s

T = 1 s v = 5 m/s

T = 2 s v = 10 m/s

T = 3 s v = 15 m/s

T = 4 s v = 20 m/s

T = 5 s v = 25 m/s

400

When drag racing, this is the amount of time it will take a car to go from 0 mi/hr to 45 mi/hr with an acceleration of 6.4 mi/hr/s.

What is 7 sec?

500

A horse slows with an acceleration of -0.5 m/s/s.  If it comes to a stop in 8 seconds, this was the horse's initial speed.

What is 4 m/s?

This is how you make a kleenex dance.

What is, "You put a little boogie in it."

200

This is why the skeleton did not go to the party.
