The propeller pushes large quantities of air backwards, i.e. imparts momentum to masses of air.
Since momentum is conserved, the boat acquires momentum in the opposite direction, i.e. forward.
Mechanical energy is a combination of its potential and kinetic energy. For example when a goes forward that is potential energy when it stops that is kinetic energy. thanks(:
The primary one is the conversion of the chemical energy in the fuel into thermal energy, which is heat energy. This is converted into mechanical energy by the jet engines, and this delivers thrust that forces the plane forward through the air. Then it's all mechanical energy conversions to provide lift and move the plane forward.
The combination of rotational force and forward movement make it possible for the screwdriver to use mechanical advantage
The energy in a car starts as electrical energy in the battery. That energy creates thermal energy in the form of a spark, which activates chemical energy in the fuel. The chemical energy converts to thermal energy which is then transformed to the mechanical energy which moves the car.
the answer is pi
Mechanical energy drives the bus forward, which is produced in the engine from the chemical energy in the fuel, and the lights use electrical energy. The chemical energy in the fuel originally comes from the Sun.
If an object has kinetic energy, then almost BY DEFINITION it has mechanical energy. "Mechanical energy" is the sum of kinetic energy and potential energy.
I don't know how to convert it, but I'll answer the second question.Mechanical energy is made from say...a Bike, the energy that makes it move and pulls it forward is considered mechanical energy. Electrical energy is made from a lightbulb, or anything that is electrical. So to answer that question..No, mechanical energy is not the same as electrical energy.Answer:Electrical Energy is consumed by, it is not made from a lightbulb or anything that is electrical... Steam (thermal energy) drives a turbine which drives a generator (mechanical energy) which produces electrical energy.No they are not the same thing aside from both being forms of energy.Electrical energy can be converted into mechanical energy such as plugging in your blender or vacuum cleaner and mechanical energy can be converted to electrical energy as mentioned in the example of the generator above.
Most of the devices that we use in society is a kind of mechanical energy. Mechanical energy is the energy of the other. Elevators. Convert electrical energy into mechanical. The car. Converted to mechanical energy is fossil. A bicycle. Muscular body converts energy to mechanical energy.
potiental energy
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
As far as I know, there is no such thing as "mechanical heat energy"; there is mechanical energy, and there is heat energy.
