Questions & Answers

Q: What is potential energy and how is it converted to kinetic energy?

Potential energy is energy stored in an object's position. When released, it converts to kinetic energy, energy of motion, as the object moves.

Q: How is the law of conservation of energy demonstrated in energy conversion?

The law states that energy is constant. In energy conversion, potential energy decreases as kinetic energy increases, maintaining the total energy.

Q: What is the formula for calculating potential energy?

The formula for potential energy is PE = mgh, where m is mass, g is gravity, and h is height, measured in joules.

Q: How is kinetic energy calculated and what factors affect it?

Kinetic energy is calculated as KE = 0.5mv^2, where m is mass and v is velocity squared. Factors affecting it are mass and velocity.

Summary & Key Takeaways

• Energy cannot be created or destroyed, only converted between forms like potential and kinetic energy.

• Potential energy is stored energy due to position, while kinetic energy is energy in motion.

• The law of conservation of energy states that energy is constant and can be converted but not lost.
