Matter
Anything that has mass and takes up space
Matter
a group of atoms that are held together by chemical bonds; a molecule is the smallest unit of a compound that keeps all the properties of that substance
Molecule
the change in position on an object due to forces
Motion
the smallest unit of an element that maintains the properties of that element
Atom
a push or a pull acting upon an object
Force
A measure of the amount of matter in an object
Mass
he attractive force that holds atoms or subunits of atoms together
Chemical Bond
a distance traveled over a period of time, example 60 mph (formula SPEED = DISTANCE รท TIME)
Speed
an arrangement of the elements in order of their atomic numbers such that elements with similar properties fall in the same column, or group
Periodic Table
the amount of force exerted per unit area
Pressure
A measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe
Weight
a substance made up of atoms of two or more different elements joined by chemical bonds
Compound
the speed and direction an object is moving (ex: 60 mph North)
Velocity
a substance that cannot be separated or broken down into simpler substances by chemical mean
Element
the force that slows down a moving object
Friction
The amount of space that an object takes up, or occupies
Volume
a solid whose atoms, ions, or molecules are arranged in a regular, repeating pattern
Crystal
an objects resistance to changing direction
Inertia
Every element has a characteristic called its
atomic number
An _______ is the smallest unit of an element that keeps the properties of that element.
Atom
The ratio of the mass of a substance to the volume of the substance
Density
the total kinetic energy of a substance's particles
Thermal energy
using a force (push/pull)to move an object (measured in Newtons)
Work
