What types of energy do runners use?

What energy does a petrol engine transfer?
Such an engine is used mainly to convert the chemical energy of the petrol into kinetic energy for various applications. And indeed it does that, but it also converts a considerable amount of the chemical energy into heat, which is generally of no use at all and must be vented into the passing air in order to avoid melting the engine.
What energy is created by a fan motor?
Inputs -> OutputsChemical Kinetic energy (movement)energy Sound energy ( from horn and engine)(from fuel) Light energy ( from front and rear lights)
A petrol chainsaw converts what source of energy?
chemical
What does the word efficiency mean when you talk about energy?
It is accepted that within the universe energy is never created or destroyed; in any process it is simply converted from one or more types of energy to one or more other types. A process is carried out with the intention of utilising one or more desired types of energy converted from others. Efficiency is the quantification of how successful that conversion is. 'Efficiency' being the proportion of desired energy obtained, 'energy loss' (which is technically incorrect) is the proportion of resulting energy arising in unwanted forms. There are eight fundamental types of energy - light, sound, heat, electric, kinetic, gravitational, chemical, elastic. A car engine uses the chemical energy in petrol to create the desired kinetic (movement) energy. In doing so the internal explosion produces unwanted heat, light and sound. Friction in the moving parts also creates heat and sound. Movement of the moving parts uses kinetic energy which reduces the amount available to move the car. Unburnt petrol is expelled into the atmosphere and retains unreleased chemical energy. Efficiency in this example is the proportion of kinetic energy derived from the petrol used.
What energy is in petrol?
chemical energy and its converted to kinetic energy
What form of energy is car moving?
Chemical energy from petrol which is converted to heat then to kinetic energy and then converted to rotational energy.
What form of energy is a moving car?
Chemical energy from petrol which is converted to heat then to kinetic energy and then converted to rotational energy.
What type of energy is a tank of petrol?
Chemical energy, Petrol is made of crude oil, it can be used to make kinetic,heat,light,sound, from burning it
Car or a fan spining sround has what type of energy?
A car converts the chemical energy in petrol to kinetic energy which makes it move along. A fan converts electrical energy into kinetic energy to make the blades turn.
How much of the energy in petrol do petrol?
Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.

kinetic

What of these energy changes occurs in a moving car?
Chemical energy of the petrol transformed into sound and heat, but mostly kinetic energy. Friction of tires on road, air resistance etc.
What do you call the energy which is stored in chemical fuels such as petrol?
Chemical Energy
What kind of energy is petrol?
Chemical energy.Chemical energy.Chemical energy.Chemical energy.
What energy conversions occur in a car engine?
Chemical energy in the petrol is converted to heat energy by igniting it with air. This causes an expansion of the gases which creates kinetic enrgy by moving pistons which connect to a crankshaft.
