Relative Density | determines whether one substance will sink or float in another |
Solid | a substance with a definite shape and definite volume |
Liquid | a substance that has a definite volume but does not have a definite shape |
Gas | a substance that does not have a definite shape or volume |
Buoyancy | the ability to float |
Conduct Electricity | the ability to allow electricity to flow through it |
Insulate/Conduct Thermal Energy | Conduct- thermal energy passes through Insulate- thermal energy stays in place |
Air Resistance | a force that opposes the motion of an object through air |
Wave | the up and down movement of surface water, light, or sound |
Wavelength | the distance between a point on one wave and the identical point on the next wave |
Transparent | objects allow almost all light to pass through it |
Translucent | objects allow some light to pass through it |
Opaque | objects do not allow any light to pass through it |
Frequency | a measure of the number of waves that pass a point in a second |
Sound Wave | is a longitudinal wave that is caused by vibrations and travels through a material medium |
Potential | energy is stored energy based on position |
Kinetic | energy is energy of motion that does work in forms of electrical light, sound, and thermal energy |
Convex | light comes together brings light into focus makes objects larger |
Concave | light spreads out lens caves in |
Parallel Circuit | an electric circuit that has more than one path for electric charges to flow |
Series Circuit | an electric circuit in which the electric charges have only one path to follow |
Solubility | the ability of a substance to dissolve when mixed with another substance |
