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: ->->->->->->->->->->->-> :
Fnet = mass * acceleration
Fnet = 12 kg * 3 m/s^2
Fnet = 36 Newtons
#$&*
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
a = Fnet / m
a = 20 Newtons / 4 kg
a = 5 m/s^2
#$&*
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: ->->->->->->->->->->->-> :
If you have a 10 kilogram object accelerating at the rate of 1.5 m/s^2, then the force
would be 15 Newtons. However, this object has a force of 20 Newtons, so there are other
forces acting on the object.
#$&*
What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
It should need 15 Newtons, but it needs 20, so there are forces in the amount of 5
Newtons working against the 20 Newton force.
