Can the kinetic energy of an object be negative? Explain your answer. Can the gravitational potential energy of an object be negative? Explain your answer. What is the kinetic energy of an automobile with a mass of 1250 kg traveling at a speed of 11 m/s? (7.6 x 104 J) What speed would a fly with a mass of 0.55 g need in order to have the same ...

Well, with no energy loss we can use conservation of mechanical energy (E): E0 = Ef . Now cancel the ½ 's and substitute for k = mg/D (d) Now consider the elastic collision as they separate... Using the Elastic Head-on Collision Thm (The relative velocity before the collision is the opposite or negative of the relative velocity after the ...

In the potential energy curve, since U(x) + K(x) = E, Since , it can never be negative. Hence the particle can never move to the left of x1. At x1, dU/dx is negative, hence the force on the particle is positive, and the particle will turn back and move to the right. x1 is called a

Mechanical Energy can be transformed into heat energy: Δ. E = - Q. Ex: a block slides to rest across a rough horizontal surface. The force of kinetic friction does negative work, and the mechanical energy of the system turns into heat energy: ...

Mechanical energy can also be used to move electrons. Generating stations use a variety of ways to turn a “turbine” which in turn causes an electrical generator to convert mechanical moving energy into electrical energy. Electrical energy is produced in generating stations and transported to your home through wires at very high voltages.

Non-conservative forces include friction, air resistance, tension, motor or rocket propulsion, push or pull by person and can either add (positive work) or remove (negative work) energy from the system. Mechanical energy is defined as the sum of the kinetic and potential energies of an object. Conservation of mechanical energy. KEi + PEi = KEf ...
Why is mechanical energy a negative value? - Quora
NOTE: the mechanical energy can be either potential energy (in which case it could be due to springs or gravity) or kinetic energy. KEi + PEi + Wext = KEf + PEf. NOTE: the work done by external forces can be a positive or a negative work term.
