Answer the following based on Newton's Second Law:
How much net force is required to accelerate a 12 kg mass at 3 m/s^2?
answer/question/discussion: ->->->->->->->->->->->-> :
force=ma
Force=12kg*3m/s^2= 36 newtons
#$&*
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
acceleration= (20kg/m/s^2)/4kg= 5m/s^2
#$&*
If you exert a force of 20 Newtons on a 10-kg object and it accelerates in the direction of your force at 1.5 m/s^2, then how do you know there are other forces acting on the object besides your own?
answer/question/discussion: ->->->->->->->->->->->-> :
acceleration= 20newtons/10kg= 2m/s^2
There is another force acting against it because the acceleration would be 2m/s^2 if there was no other forces.
#$&*
What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total of the forces is 0.5 newtons in the direction opposite of the force you applied.
