How do tidal power plants generate electricity? A barrage stores water during high and low tide. When the water is released, it turns the plant's turbines.

A barrage stops water from flowing out at low tide, creating a force that turns the plant's turbines.

A barrage holds back water during high tide. The force of the water against the barrage turns the plant's turbines.

A barrage allows water to flow during high and low tide, this turn's the plant's turbines.

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.
