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: ->->->->->->->->->->->-> scussion:
Force = mass * acceleration
12kg * 3m/s^2 = 36Newtons
#$&*
*
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
20N = 4kg * accel accel= 5m/s^2
#$&*
*
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: ->->->->->->->->->->->-> scussion:
10 * 1.5m/s^2 = 15 Newtons, when the Force I exerted was equal to 20N. Theirfore there must be 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: ->->->->->->->->->->->-> scussion:
The total of the forces would be 15N, I would assume that friction was providing a force of -5N in the opposite direction of the
force I was applying. 20N+ -5N = 15N
