Jerri is planning to rebuild the engine of an antique car. she has chosen all the materials she needs including a high quality synthetic oil to reduce friction in the engine. what effect will reducing friction have on the engines performance?

There are several answers for this question, although the main effect that we can find with friction reducing on an engine is reducing the heat transfer between the moving parts.

Reducing the friction between two moving parts means reducing the heat transfer. One of the more important effects of the engine oil is to reduce the friction between the moving parts, which means reducing the heat generation or heat transfer, and it's especially true when we are talking about synthetic oil (synthetic engine oils can resist heat transfer better than traditional engine oils).

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.
