strength or energy as an attribute of physical action or movement.
What is Force
100
Proton
What is a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
100
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
What is Convection
100
the point on which a lever rests or is supported and on which it pivots.
What is Fulcrum
100
System
What is a set of connected things or parts forming a complex whole, in particular.
200
the rate at which something occurs or is repeated over a particular period of time or in a given sample
What is Frequency
200
Inertia
What is a tendency to do nothing or to remain unchanged.
200
a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
What is Electromagnetic Radiation
200
an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
What is Gas
200
Variable
What is not consistent or having a fixed pattern; liable to change.
300
the resistance that one surface or object encounters when moving over another.
What is Friction
300
Speed
What is the rate at which someone or something is able to move or operate.
300
the strength and vitality required for sustained physical or mental activity.
What is energy
300
a plane inclined at an angle to the horizontal.
What is Inclined plane
300
Evaporation
What is the process of turning from liquid into vapor.
400
movement, or a tendency to move, toward a center of attractive force, as in the falling of bodies to the earth.
What is gravitation
400
Trough
What is a long, narrow open container for animals to eat or drink out of.
400
The conversion of one form of energy into another, or the movement of energy from one place to another. Solar panels allow for energy transfer from light energy to heat and electrical energy.
What is Energy transfer
400
a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
What is Lever
400
Heat
What is the quality of being hot; high temperature.
500
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.
What is Gravity
500
Velocity
What is the speed of something in a given direction.
500
a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
What is Entropy
500
the natural agent that stimulates sight and makes things visible.
What is Light
500
Kinetic energy
What is energy that a body possesses by virtue of being in motion.
