How close to your target you are/ how close your measurement comes to the actual measurement
the shortest, straight line between where an object begins its motion and the place where it comes to rest
A type of longitudinal wave that originates as the vibration of a medium as it travels through gases, liquids, and elastic solids
A substance that makes possible the transfer of energy from one location to another, especially through waves.
Perceived change in frequency due to either motion of the source or motion of the observer
the complete range of electromagnetic waves placed in order of increasing frequency
Intensity (sound and light)
Sound:the average rate at which sound energy is transmitted
Light:The amount of energy given off by a light
the action of a wave bouncing off an object
Rough: Light bounces off and is reemitted in many different directions
Smooth: Light is scattered back at same angle as original wave
the average mass of one atom of an element
When atomic number is subtracted from it, you are left with the number of neutrons
an electron that is found in the outermost shell of an atom and that determines the atom's chemical properties
atoms of the same element that have the same atomic number but different atomic masses due to a different number of neutrons
gravitational energy, kinetic energy, heat energy, elastic energy, electrical(electromagnetic) energy, chemical energy, and nuclear energy
Law of Conservation of Energy
the law that states that energy cannot be created or destroyed but can be changed from one form to another
A type of change that alters the physical properties of a substance but does not change its composition.
pH is lower than 7. Main part of an acid is Hydrogen. Properties are sour taste, reactivity with metals and ability to produce color changes.
pH is higher than 7. Produces hydroxide ions. Properties include bitter taste, slippery feel, and ability to produce color changes.
Type of motion where velocity is constantly changing because direction is continuously changing. Motion that goes in a circle.
Newton's First law of Motion
An object at rest will stay at rest and and object in uniform motion will remain in uniform motion unless acted upon by an unbalanced force. (inertia)
Newton's Second law of Motion
The force acting on an object is equal to the mass of the object multiplied by its acceleration. F=ma
Newton's Third law of Motion
For every action is an equal and opposite reaction. Action/Reaction pair.
Newton's Universal Law of Gravitation
any two objects exert a gravitational force of attraction on each other
a force directed toward the center of the circle for an object moving in a circular motion.
Fictitious force, peculiar to circular motion, that is equal but opposite to the centripetal force that keeps a particle on a circular path
Simple Binary Compounds
materials/substances that exhibit only one type of strong chemical bond: metallic, ionic or covalent.
