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 = m*a
Fnet = 12kg * 3 m/s/s = 36 N
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
20 N = 4 kg * a
a = 5 m/s/s
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: ->->->->->->->->->->->-> :
20 N = 10 kg * a
a = 2m/s/s
the object would be accelerating 2m/s/s if there was no other forces acting on the object but since the acceleration is 1.5m/s/s you know that there is other ofrces acting on the object.
What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
1.5m/s/s * 10kg = 15 N
20 N - 5 N = 15 N in the direction of my force
