Fill in the Blanks Vocabulary BeatdownOnline version This is an fill-in the blank activity for core vocabulary and concepts of force, motion, and energy by Shavonta Wilkerson 1 Energy speed collides mass less direction potential greater fast stored force Kinetic direction waiting state resistance low high motion is what's needed to cause change . Potential energy and kinetic energy can describe the of energy . Similar to money stored in a bank just in case someone need to purchase an item , energy is energy . Energy in this state is to be used . Potential energy change to a state of kinetic energy as soon as energy is being used . energy is energy in motion . Motion is very important when discussing energy . Motion can be described in terms of and . Speed is how an object is moving . Words like up , down , beside , in front of , left , right , and behind describes an object . An object will remain in motion until another object with it . This collision , or , can change an object - - direction and speed . Depending on the of an object , a given force may or may not cause a great change in an object motion . Friction is a force that creates to the motion of an object . When a surface has friction , like newly fallen snow , the the resistance to motion . When a surface has friction , like an ice - skating ring , the the resistance to an object's motion .
