Answer:
Potential energy can be defined as the energy in a body due to its position
In simple terms potential energy is the energy at rest
Explanation: Examples ;
- A spring has more potential energy when it is compressed or stretched.
- A steel ball has more potential energy raised above the ground than it has after falling to Earth.
C describes plastics that can be recycled. Thermoplastic can be remolded and reheated after forming, whereas thermoset strengthens when heated
Tops stops spinning because it doesn't have energy or ran out of force for example when you spin a top you give force to it then after 30 sec it going to stop going slower and slower that Is losing energy that's how tops stops spinning
Using a stove to heat up water.
