What does "F=ma" mean in Newton's Second Law? | How Things Fly  Oct 17, 2011 ... A: Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).

According to Newton's third law of motion, every action has an equal ...  Indeed, every action in the universe is symmetric. The force one object exerts on a second object is always equal to the force that the second object exerts on the first. When your feet push the Earth with a force of a few Newton, then the Earth pushes at your feet with the same force.

Newton's Third Law - The Physics Classroom  Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
