George Jackson is the founder and lead contributor of Physics Network, a popular blog dedicated to exploring the fascinating world of physics. At room temperature, it will go from a solid to a gas directly. The formula of Newtons Second Law of Motion is \(F = m \times a\). 1 : a statement in dynamics: a body at rest remains at rest and a body in motion remains in uniform motion in a straight line unless acted upon by an external force. Force exerted by an object equals mass times acceleration of that object: F = m * a . So the acceleration of the object is directly proportional to the force and inversely proportional to the mass. The equation F net = m a F net = m a is used to define the units of force in terms of the three basic units of mass, length, and time (recall that acceleration has units of length divided by time squared). The size of the forces on the first object equals the size of the force on the second object. Newtons first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force. Newtons Laws of Motion are as stated below: Newtons First Law of Motion: According to this law, a body continues to be in its state of rest or of uniform motion along a straight line unless it is acted upon by some net unbalanced external force to change the state.
