Dependent Variable | whose value depends on that of another. |
what is Newtons 1st | An object at rest will remain at rest unless acted on by an unbalanced force. |
What is Newtons 2nd | The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. |
What is Newtons 3rd | For every action, there is an equal and opposite reaction. |
Direction | Direction is when the person or thing is in their point of view |
