Can the total mechanical energy E = K + U ever be negative? Explain.
Can the total mechanical energy E = K + U ever be negative? Explain.
Homework Answers
Here,
Yes, because K can be negative.
As In any collision momentum is always
conserved.
In a perfectly elastic collision mechanical energy is conserved
whereas in an inelastic collision mechanical energy is not
conserved as some is converted to heat or work to deform the
objects.So, k can be negative.
