inertia=an object will keep moving unless unless acted upon by an unbalanced force

1st 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 :)

second law: when force is applied to an object, acceleration is made

@imqwerty you are contradicting yourself
imqwerty

lol :D

@heretohelpalways not quite. Pay attention to the proportion
anonymous
  • anonymous
between the force applied and resulting acceleration.
anonymous
  • anonymous
with mass being the constant
anonymous
  • anonymous
As well as the resulting acceleration with changing mass with constant being the force applied.
anonymous
  • anonymous
Try to draw a relationship and describe each of them
anonymous
  • anonymous
mass*acceleration=force
anonymous
  • anonymous
yes
anonymous
  • anonymous
BUt
anonymous
  • anonymous
Try to explain the relationship between the amount of force applied and resulting acceleration.
anonymous
  • anonymous
AND relationship between mass and acceleration given a force assumed to be constant
anonymous

example: 300*0.07= 21 newtons
anonymous
  • anonymous
Yes.

Final 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.

how did i contradict myself

elaborate
anonymous

balanced forces=net force of zero=that's not the case
anonymous

hmmmmm, I'll think of something
anonymous

Oh astrophysics came
anonymous
  • anonymous
recoil of a gun when it fires
anonymous
  • anonymous
That's a spot on
anonymous
  • anonymous
can you elaborate the concept?
anonymous
  • anonymous
Why 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.

example of 3rd law - when u walk u put force on ground nd the ground puts a normal force on u wid the help of which u can walk :)

Mr. Astrophysics what have you got to say?

I'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!

Interesting, 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\[\vec{F} = m \vec{a}\]

Actually Newton proposed his second law as such, considering momentum \[\vec F = \frac{ d \vec p }{ dt }\]
