Newtons second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics. Inertia of motion is defined as the inability of a body to change it state of motion by itself. Object thrown from a height. This also means that the harder you kick a ball the farther it will go. At room temperature, it will go from a solid to a gas directly. Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). What are three examples of Newtons second law in everyday life? This also means that the harder you kick a ball the farther it will go. Any object has a tendency to stay in its current state. We can see this equation for force from the second law of motion. For an object at rest, the applied force produces acceleration in the object and makes the object move in the direction of applied force. Newtons second law is a quantitative description of the changes that a force can produce on the motion of a body. Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.
