Motion

In this instructable I would like to explore the world of motion. It's just like lesson of physics dealing with the basic knowledge of motion. It first struck me when I was reading the chapter myself. There are no other needs except concentration on the subject.

Law1- every object remains at rest or in motion at a steady rate until it is acted upon by another force
Law2- the amount of force required to change the speed of moving object depends on the mass of acceleration required.
Law3- that to every action there is an equal and opposite reaction.
NOTE: rockets work on the 3rd law of motion.

Speed- distance traveled per unit time ( scalar quantity )
Velocity- distance traveled in a specific direction per unit time ( vector quantity )
Acceleration- the rate of change of velocity per unit time. ( vector quantity)
Distance- actual length covered by the body irrespective of the direction and path. (Scalar)
Displacement- the shortest path joining two points respective of the direction and always on a straight path.(vector)

Speed = distance / time(v)
Velocity= distance in a specific direction/ time.
Distance = average velocity * time
Average speed = total distance /total time
Average velocity = initial v. + final v.
Acceleration = final v. - initial v./ time
