What else can I help you with?
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
How mechanical energy gets converted to thermal energy along the track?
As the mechanical energy of the moving object interacts with friction from the track surface, some of this energy is transformed into heat due to the resistance encountered. This frictional force opposes the motion, causing the mechanical energy to be dissipated as thermal energy into the environment.
What is the sign of the work done by the frictional force?
The work done by the frictional force is negative because the force opposes the direction of motion. This means that the frictional force removes mechanical energy from the system by transforming it into heat, resulting in a decrease in the object's kinetic energy.
What is The force that opposes the movement of energy?
Kinetic Energy :D
Is holding an egg mechanical energy?
No mechanical energy is needed to hold up an object. Mechanical work (transfer of energy) is done when applying a force over a certain distance. Don't confuse force and energy (or force and work).
Mechanical energy is the energy due to what?
It is the energy expended by a mechanical force acting over a distance.
What is the function of spiral spring in physics?
In physics, a spiral spring is used to store mechanical energy when it is compressed or stretched. It can be used in various applications such as in mechanical clocks, wristwatches, and suspension systems. The spring exerts a force that opposes the deformation, making it a key component in many mechanical systems.
What else can mechanical energy be called?
force
What is meant by coupling magnetic field in electromechanical energy conversion?
Coupling field is link between electrical and mechanical energies in electromechanical energy conversions. If the output is mechanical (motor), coupling field reacts with input electrical energy in terms of Back EMF which opposes the input. Coupling field absorbs energy from electrical system, converts and delivers mechanical energy. If output is electrical (generator), coupling field reacts with input mechanical energy in terms of Magnetic Drag which opposes the input. Coupling field absorbs energy from mechanical system, converts and delivers electrical energy.
What is a force that opposes motion between surfaces that are tuching?
Friction is an opposing force; the kinetic energy of the movement of the two touching surface will be converted to heat energy.
What is the energy called when mechanical energy decreases and temperature increases?
Force
Can workdone by friction be positive?
No, work done by friction is always negative because it opposes the direction of motion. Friction always acts in the opposite direction to the force causing the object to move, resulting in a loss of energy and a decrease in the total mechanical energy of the system.
