The process when energy changes from potential energy to kinetic energy it is called ______ ________.
energy transfer
The force that is responsible for pulling objects toward Earth is called _______.

Repel
Of the 3 systems we used to move our vehicles which one had the least friction when properly constructed?
A) The drop weight system
B) The Rubber band System
C) The Magnetic Levitation System
The Magnetic Levitation System
(Explanation: This system has the least friction because there was the fewest parts rubbing together, which is what creates friction)
What is the name of the star in our solar system?
The Sun
How does winding a rubber band affect the amount of potential energy a rubber band has?
The more you wind a rubber band the more potential energy the rubber band will have.
When force on an object is increased and the amount of friction on the object is decreased, what will happen to the motion of the object?
The object will speed up or move more quickly.
What is the name for the type of force created by a magnet?
Magnetism or Magnetic

or
Add weight
What is the name of our galaxy?
The Milky Way Galaxy
Name 3 types energy that cause motion.
Solar Energy

Magnetic Energy
Geothermal Energy
Biofuel Energy
Tidal Energy
If the amount of force pulling an object is equal to the amount of force pushing an object this is called a _ _ _ _ _ _ _ _ force
Balanced force
How must you arrange the poles of two magnets to make them attract each other, and how must you arrange the poles of two magnets to repel each other?
Attract: Opposite poles face each other; North to South or South to North.
Repel: Like poles face each other; North to North or South to South.
Thinking about Friction and Force, how could you design a vehicle to go the fastest?
Make the vehicle have the least amount of friction and the most amount of force.
