State the characteristics of an ideal fuel.

Ideal fuel shows the following characteristics:

It should be less expensive,

It should be easily available,

It should produce a large amount of heat,

It can be transported easily.

It has high calorific value.

It should burns easily in air at a moderate rate

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
