What is the formula for speed?
Speed = Distance / Time
100

What is the formula for velocity?

Velocity = Distance / Time with a direction (must be with a direction)

100

What is the formula for acceleration?

Acceleration = Final Velocity - Initial Velocity / change in time

100

The definition of motion.

When an object's distance from another object changes.

100

The ability to do work.

What is energy?

200
How is speed different from velocity?
velocity needs a direction
200

What is the velocity of an object that is moving 6 meters in 2 seconds east?

3 m/s east

200

What are three ways we can tell if something is accelerating?

increasing its speed; decreasing its speed; changing direction

200

What you use to determine if something has moved.

Reference Point

200

This law tells us that energy cannot be created or destroyed but only transformed from one form to another. 

What is the Law of Conservation of Energy?

300
What is the average speed of a cow that walks east 60 meters in 120 seconds? (Remember, the units must be m/s or km/hr)
0.5 m/s
300

Distance = 20 meters Time = 4 seconds Direction = south What is the velocity of this object?

5 m/s south

300

Final Velocity = 60 m/s south Initial Velocity = 50 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?

2 m/s2 south

300

 The distance in a straight line between an object and its original reference point is known as this.

What is displacement?

300

These sources of energy come from our fossils fuels, they are also not easily replaced.

What are non renewable resources?

400
A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?
40 meters
400

An object travels 25 meters in 2 seconds east. What is it's velocity?

12.5 m/s east (must include direction!)

400

If Jackson is riding his bike at 20 mph then turns right onto a trail and continues riding his bike at 20 mph has he accelerated?

Yes, he changed direction therefore he accelerated.

400

If you were skating on a skateboard and all of a sudden the skateboard hit a rock, what would happen to you?  Which of Newtons Laws would this best represent?

You would continue to fall forward until to you hit the ground, because Newton's First Law states an object in motion will remain in motion unless acted upon by an unbalanced force. 

400

A rubber band has energy stored based on its ability to bend, flex or stretch.  Also known as this. 

What is Elastic Potential Energy

500

What is the speed of an object moving east for 6 seconds at 105.3 m/s?

105.3 m/s

500

A pink alien moved south in its spacecraft for 2 km at a rate of 20 m/s. How much time did it take him to do this in seconds?

100 s

500

If Leah was running a race at 4 m/s then she saw Sara catching up so she sped up finishing the race 4 seconds later at a speed of 12 m/s.  What was her acceleration during this point of the race?

2 m/s2

500
If you are unloading groceries from your car and putting them away in your house, has work been done?  Why or why not?

Yes work has been done, because you are using force to move an object a distance. 

500

This form of energy often associated with heat, is usually a byproduct of most energy transformations and lost because of friction.

What is thermal energy?
