Constant Acceleration Motion
In the
standard model of friction
, the frictional resistance is given by the
coefficient of friction
times the
normal force
.
For this case the normal force is just the
weight
of the object.
Application of
Newton's second law
to a single mass.
If an applied force F=
N is opposed by friction with friction coefficient mu =
acting on mass m=
kg then the frictional resistance force is
N and the net force is =
N. Newton's second law becomes:
Net force
=
mass
x
acceleration
Net force =
N =
kg x
m/s²
You may edit any of the data. When finished with data entry, click on the quantity you desire to calculate in the formula above. Quantities will not be forced to be consistent until you click on the desired quantity.
In U.S. common units this becomes:
Net force =
lb =
slug x
ft/s²
In this system the weight on the earth's surface is
lbs.
