What is the difference between potential and kinetic energy?
+
Potential energy is the energy stored in an object due to its position or configuration, while kinetic energy is the energy of motion. Potential energy can be converted into kinetic energy and vice versa.
Can an object have both potential and kinetic energy at the same time?
+
Yes, an object can have both types of energy at the same time. For example, a ball rolling down a slope will have potential energy due to its height and kinetic energy due to its motion.
How does energy conservation work in everyday life?
+
Energy conservation is observed in daily life whenever energy is converted from one form to another. For instance, when you swing on a swing, you convert potential energy at the highest point into kinetic energy at the lowest point, and then back again.
What are some common sources of potential energy?
+
Common sources include gravitational potential energy (e.g., a book on a shelf), elastic potential energy (e.g., a stretched spring), and chemical potential energy (e.g., food we eat).
