Förstå potentiell energi

Potential energy is the energy an object possesses due to its position relative to a reference point (usually the ground). Det beräknas med följande formel:

* pe =mgh

Där:

* PE is potential energy (measured in Joules, J)

* m är objektets massa (mätt i kilogram, kg)

* g is the acceleration due to gravity (approximately 9.8 m/s²)

* h is the height above the reference point (measured in meters, m)

Beräkning

1. Identifiera värdena:

* m =4 kg

* g =9,8 m/s²

* h =5 m

2. Anslut värdena till formeln:

PE =(4 kg) * (9.8 m/s²) * (5 m)

3. Beräkna:

PE =196 Joules (J)

Answer: The potential energy of the 4 kg object 5 meters above ground is 196 Joules.
