Newton's Three Laws of Motion
*Law of Inertia- tendency of an object to resist the changes
*Law of Interaction- in every action there is equal or opposite reaction
*Law of Acceleration- the greater the mass ,the greater is the amount of force                                        needed to move an object

Law of Inertia- a body will remain at rest at rest and motion will remain motion with the same speed and direction UNLESS THEIR IS AN UNBALANCE FORCE in it.
Forces- can be made to moved stop or change its direction by pushing or pulling
Motion- stay at rest
Balance Force- two forces acting upon an object is balance force if the magnitude is equal but opposite in direction. It should must lie along the same line
Unbalance Force- changing its motion
Friction- a force tends to oppose the motion of the object

Acceleration- change in velocity, a vector quantity
Laws of Acceleration- acceleration pertains no balance. It dependent in two variables- Net Force (the summ of all forces) and the mass (amount of matter of the object)
The force increases, acceleration increases (Directly Propotional). Mass increases  acceleration decreases (inversely propotional).
Speed- the rate in change of positiion

Laws of Interaction (Action-reaction)
-For every action their is equal and opposite reaction-
