A change that produces one or more new substances with new chemical properties.

A combination of substances in which no reaction takes place.

A change in position.

Force x Distance

The amount of force needed to produce a given change in the motion of an object depends on the mass of the object. The larger the mass, the more force is needed to give it a certain acceleration.

Painting a wall, boiling water, or shredding cheese.

A chemical change in which elements are combined or rearranged.

The rate at which the position of an object changes.

The metric unit of measurement for calculating work.

A compound that contains the hydroxyl (OH) radical.

This chemical or paper tells whether a substance is an acid or a base.

A substance that is altered or changed in a chemical reaction.

The speed and direction in which an object is moving.

The amount of work a person does in a given period of time.

A statement that uses symbols, formulas, and numbers to stand for a chemical reaction.

Leveled spaces in which electrons move around the nucleus of an atom.

A reaction in which elements combine to form a compound.

If no force acts on an object at rest, it will remain at rest. If an object is moving, it will continue moving at the same speed and direction if no force acts on it.

Work/Time (Work divided by time)

A push or a pull.

Tastes sour, has a pH less than 7, contains hydrogen, and turns litmus from blue to red.

A reaction in which the elements in two compounds are exchanged.

If an object exerts a force on a second object, the second object will always exert a force on the first object. Sometimes this idea is stated as "For every action, there is an equal and opposite reaction."

The unit of measurement for power.

The ability to do work.
