Forcee
What is strength or energy as an attribute of physical action or movement.
200
Element
What is a part or aspect of something abstract, especially one that is essential or characteristic.

Gravity
What is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

Of or relating to a compound that does not ionize in solution. Of or relating to a particle, an object, or a system that has a net electric charge of zero.
300
Energy
What is the property of matter and radiation that is manifest as a capacity to perform work (such as causing motion or the interaction of molecules).
300
Matter
What is physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
300
Variable
What is an element, feature, or factor that is liable to vary or change.
400
Speed
What is a measure of movement.
400
Neutron
What is a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
400
Heat
What is heat seen as a form of energy arising from the random motion of the molecules of bodies, which may be transferred by conduction, convection, or radiation.
400
Volume
What is the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.

Friction
What is the resistance that one surface or object encounters when moving over another.
500
Electron
What is a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
500
Evaporation
What is the process of turning from liquid into vapor.
500
Vibration
What is an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
500
Independent variable
What is a variable (often denoted by x ) whose variation does not depend on that of another.
