according to law of conservation of energy is tht energy is converted from one form to another WD is energyThank you for your explantions. May I know why WD BY DRIVING FORCE= WD by Kinetic energy + WD BY FRICTION + Gain in gpe? I can't imagine it.
so when an object travels up an inclined plane the total WD by driving force is utilised in various forms
while travelling up the plane some WD will be done in gaining height u see an inclined plane always has some height,...so it will be equal to WD by GPE
some energy will be utilized for motion so WD is done by Kinetic energy.....
if there are resistive forces present like friction ...WD will be done against Friction (WD = force*distance) nd friction is a force
This formula is the base of energy conversions for inclined plane ques in our syllabus
it is altered according to the situation given in the question...
there can b conditions where either one of the factors will be eliminated for eg
on smooth surfaces no WD against Fr will be done
or if speed is constant no change in speed will occur thus Ke will be 0J etc
Hope u got it now
