Newtons first law - an object remains in the same state of motion unless a resultant force acts on it. If the resultant force o an object is zero, this means, Newtons second law - resultant force = mass × acceleration, Newtons third law - whenever two objects interact, they exert equal and opposite forces on each other., Hooks law - Extension happens when an object increases in length, and compression happens when it decreases in length. The extension of an elastic object, such as a spring, Terminal velocity - the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. For example, a skydiver falling spread-eagled through the air reaches a maximum speed of about 53 m/s.,
