(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

the rate at which an object covers distance
Speed
a comparison of the energy output to the energy input in a given system
Efficiency
the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other
Friction
a mechanical device that changes the direction or magnitude of a force
Simple Machine
the initial force used to get a machine to begin working
Input Force
the vector sum of forces acting on a particle or body
Net Force
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed
Constant Speed
the rate of change of position with respect to a frame of reference; a function of time
Velocity
the total distance traveled by the object divided by the elapsed time to cover that distance
Average Speed
the phenomenon in which an object changes its position over time
Motion
a force where two forces of equal size, act on a body, in opposing directions
Balanced Force
an abstract coordinate system and the set of physical reference points that uniquely fix the coordinate system and standardize measurements within that frame
Frame of Reference
the rate of change of velocity per unit of time
Acceleration
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors
Potential Energy
when the speed of an object is constantly changing
Instantaneous Speed
the force exerted on an object by a simple machine
Output Force
an amount of space between two things or people
Distance
the energy that is possessed by an object due to its motion or due to its position
Mechanical Energy
strength or energy exerted or brought to bear
Force
moving but returning to the original position
Displacement
a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement
Work
a force exerted by a machine or in a process
Effort
a principle stating that energy cannot be created or destroyed, but can be altered from one form to another
Conservation of Energy
when two forces acting in opposing directions are not equal in magnitude and in size
Unbalanced Force
