Best ResponseYou've already chosen the best response.11st law  a body tends to remain at its original position. :) nd this is called inertia .example  when u shake a tree the fruits fall down cause they try to resist any change in their original position nd thus they fall :)

Best ResponseYou've already chosen the best response.0Final answer being the applied force and resulting acceleration have a PROPORTIONAL RELATIONSHIP whereas mass and acceleration has INVERSE PROPORTIONAL RELATIONSHIP when force is kept constant.

Best ResponseYou've already chosen the best response.0Why aren't you shooting yourself with that? Why does recoil not kill you? Account for the drastic difference of surface areas being responsible for dispersion of forces into two opposite directions perfectly alined with one another.

Best ResponseYou've already chosen the best response.2I'll keep it simple I suppose. Newton's first law is a body acted on by no net forces with constant velocity (that means 0 acceleration) you can see this with a linear position time graph. You can also see this on a ice hockey table, the slicker the surface further the puck slides (given an initial velocity of course). So what you want to see from here is that when a body is at rest or moving with a constant velocity, we say it's at equilibrium, mathematically. \[\sum \vec F = 0\] don't forget the components! Newton's second law of motion is simply is net force = mass x acceleration, \[\sum \vec F = m \vec a\] writing it out we can say if a net external force acts on a body, the body accelerates. The direction of acceleration is the same as the direction of the net force where the m x a = the net force. I think you can think of your examples for this, pretty straight forward. Newton's third law often called action  reaction, it is stated as if a body A exerts force on body B (action) , then the body B exerts a force on body A (reaction), the two forces have the same magnitude but are opposite in direction. \[\vec F_{A~on~B} =  \vec F _{B ~ on~A}\] it's like a rocket blasting off, or kicking a ball, anything really. Hope that helps!

Best ResponseYou've already chosen the best response.0Interesting, Newton formulated his Second Law as a way to define acceleration, saying that a net force acting on a mass produces an acceleration in the same direction as the net force, i.e.\[\vec{a} = \frac{ \vec{F} }{ m }\]Only later was it adopted in its now familiar form\[\vec{F} = m \vec{a}\]

Astrophysics

Best ResponseYou've already chosen the best response.2Actually Newton proposed his second law as such, considering momentum \[\vec F = \frac{ d \vec p }{ dt }\]
