Factor the changes as a result of changes in the other variables. |
|
|
Independent variable |
Factors that, as it changes, affects the measure of another variable. |
|
|

|
|
Newton's first law
|
states that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it
|
|
|
Newton's second law |
States that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by its mass |
|
|
Newton's third law
|
states that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction
