What are the 3 states of matter? Solid, liquid, gas
Volume: the amount of space matter takes up. You can find the volume of an object by seeing how much water it displaces.
Weight: The force of gravity on an object. Not to be interchanged with mass.
Physical changes: do not alter the molecular structure but do alter the physical appearance of the matter.
Chemical changes: alter the molecular structure of matter
Density: the ratio of mass to volume.
Chemical reaction: 2 or more compounds can combine or break down to form new compounds with new molecular structures.
Element: made of one type of atom. Each element is represented by one or two letter and a number. Each element has an atomic number which is the number of protons in the atom.
Compound: made of several types of atoms chemically combined in specific proportion
Mixture: made of several types of molecules but not chemically combined.
Molecule: the smallest particle of a substance that retains properties of the substance and can exist independently.
Atoms: invisible, basic building block of matter made up of protons, neutrons, and electrons.
Protons and Neutrons are in the Nucleus. Protons have a positive charge.Neutron have neutral charge.
Electrons are in the outer portion of the atom. They have a negative charge.
Heat: the energy of a moving molecule
Energy: the ability of matter to move other matter or produce a chemical change
3 Types of Energy Heat energy- electrical energy, Mechanical energy- wave energy, Chemical energy- nuclear energy
Celsius scale: 0 degrees is freezing and 100 degrees is boiling.
Fahrenheit scale: 32 degrees is freezing and 212 degrees is boiling
Temperature: the measure of how hot or cold a body is in relation to a standard.
Force: a push or pull
Two types of force and examples 1) contact- machines(mechanical), 2) distance (magnetic force)
Electrostatic Force: the power resulting from electricity as an attractive or repulsive interaction between two charged objects. Positive and negative oppositely charged objects will attract each other. Like charges will repel each other.
Gravitational force: the attraction or pull of objects in the universe toward one another such as the moon, the sun, and Earth.
Magnetic Force: the materials that will attract materials made of iron, steel, cobalt, or nickel. The magnet is strongest at the ends or poles.
Friction- surfaces that touch have resistance to motion. Produces Static Electricity
Two types of friction and what they do? static- objects touch...no move, kinetic- objects touch and move
What is the direction of friction force? Opposite of the direction of motion.
Static Electricity: Rubbing materials together cause the transfer of electrons from one material to another. (make item more negatively charged)
• Centripetal force is a force that makes a body follow a curved path.
• Inertia is the resistance for an object to change its state of motion.
• Unbalanced Force: always causes a change in motion. The object with the greatest force will cause the other object to move.
• Balanced Force: does not cause movement because two objects are balanced.
• Centrifugal force represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation.
