Newton's First Law of Motion , the law of inertia, states that an object in a state of equilibrium will remain at rest or, if in motion, will maintain a uniform(constant, straight-line) velocity, unless it is acted upon by an unblanced force.

Newton's Second Law of Motion,when an unbalanced net force acts on an object, the object is accelerated in the direction in which the force acts. For a given object, the larger the unbalanced force, the greater the resulting acceleration.

Newton's Third Law of Motion,whenever one object exerts a force on a second object, the second object exerts an equal force on the first object, but the oppsite direction.

Matter is material substance that occupies space, has mass, and is composed predominantly of atoms consisting of protons, neutrons and electrons, that constitutes the observable universe, and that is interconvertible with energy.

Energy is the ability to be active; strength of body or mind to do things or to work.
