1. We feel warm when we put our hand above the candle but can't feel warm in the sides. Why?

It is because convection take place. Convection is a transfer of heat by the movement of gases or liquid where warm air is less dense than cold air so hot air rises and cold air sinks.

(Correct me if I am wrong)

magnityde and direction

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.
