Newton's laws:I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Meaning ---->an object that has a constant speed tends to remain the same speed until a force is applied to it.
II. The relationship between an object's mass (m), its acceleration (a), and the applied force (F) is F = ma. Acceleration and force are vectors (as indicated by their symbols); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Meaning---->f = ma
III. For every action there is an equal and opposite reaction.
Meaning---->This law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction.
