(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Explain what is meant by the conservation of mechanical energy. Write the corresponding equation in detail (in terms of mass speed ect.)

a) If friction is not truly negligilble, how would you insert the influence of friction in the equation of the above question? Write the corresponding equation in detail.

b) If friction isnegligible which should be the larger megnitude, potential energy or kinetic energy?not

2. Relevant equations

PE=mgh

KE= .5(m)(v)^2

E=PE+KE (I am not sure if this is the right equation for mechanical energy?)

3. The attempt at a solution

I need help with this part. I am not sure what they mean by the conservatiob of mechanical energy equation, do they want KE=-PE or E=KE+PE or some other equation. Also I am unsure about how to addd friction into the meechanical energy equation, basically I need help with everything!!! Please help!!
