Gravitational potential is referred as the energy spent to move the mass from one point to another. It is represented in the unit as Joules per kilogram.
Gravitational potential energy = m * g * h where m denotes the mass of the object, g denotes the acceleration due to gravity which is 9.8 m / s 2, and h denotes the height in meters.
The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm.
