Science Vocabulary

TermDefinition
position An objects position is its location point.
distance the amount of space between one point and another
displacement The method to determine the volume of a volume ofa solid object using the difference in water volume before and after the addition of the object.
speed The distance traveled per unit of time.
velocity The speed and direction of a moving object.
time The measured or measurable period during which an action, or progress, or condition exists or continues.
position An objects position is its location point.
law of conservation of energy Energy cannot be created out of nothing,nor can it be completely destroyed. Energy can only change its form.
10. potential energy The amount of energy that is stored in an object
kinetic energy the energy an object has because of it's motion
reflection a change in the direction of a wave when it hits a barrier and bounces back
refraction a change in the direction and velocity which occurs when a seismic or electromagnetic wave travels from one material into another of different density, state, or elasticity
absorption a physical process in which a substance takes in a given amount of another substance
wavelength the distance between one peek and the next on a wave
frequency The number of cycles a wave completes in a period of time. The number of times something happend.
gravity A force that exists between any two objects that have mass.
mass The amount of matter in an object.
distance (effect on gravity) the amount of space between one point and another
weight The force of gravity on an object.
inertia An object's resistance to a change in motion
law of universal gravitation The law that states that the gravitational force increases the mass of two objects increases and decreases as the distance between abject increases.
rotation A wheel on a car spins on its axis but dose not move.
orbit
revolution the orbiting of an object around another object
seasons a period of the year determined by the position of the earth as it revolves around the sun
