Which statement expresses Newton's first law of motion?
A) An object with no force on acting on it continues at rest or moves in uniform motion in a straight line with constant velocity.
B) An object with a force on it is accelerated in the direction of the force an amount inversely proportional to its mass and directly proportional to the size of the force.
C) For every action, there is an equal and opposite reaction.
D) The force between two objects is directly proportional to the product of their masses and inversely proportional to the distance between them squared.
E) The force between two objects is inversely proportional to the product of their masses and directly proportional to the distance between them squared.

Newton's first law of motion, also known as the law of inertia, states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is accurately reflected in choice A.
