State Newton's laws of motion.
Answers
:
Law I: Every material body continues in its state of rest, or of uniform motion in a straight line, unless it is acted upon by an external force.
Law II: The rate of change of momentum of a body is proportional to the resultant applied force, and takes place in the direction of the force.
Law III : To every action (force) there is always an equal in magnitude) and opposite (in direction) reaction (force).
OR
Action and reaction are always equal in magnitude and opposite in direction, and act on contrary parts.
Following are the Newton's laws of motion
1st law - an object remains in a state of rest or of uniform motion INA straight line unless compelled to change that state by an external unbalanced force applied on it
2nd law - the rate of change of momentum of an object is directly proportional to the applied unbalanced force on it and takes place in the direction of force applied
3rd law - to every action, there is an opposite and equal reaction. The action reaction forces act simultaneously for same time on two different objects interacting with one another .
