Copy of Lesson 1 ~ Energy Transformation

Multiple Choice

Why is it important to understand how energy can be transformed from one form to another?

• It helps us save money on electricity.

• It allows us to predict and control physical phenomena.

• It makes cooking easier.

• It helps us understand weather patterns.

Multiple Choice

What is heat?

• Heat is a type of light energy.
• Heat is the energy transferred due to temperature difference.
• Heat is the force exerted by moving objects.
• Heat is the mass of an object at high temperature.

Multiple Choice

Explain how energy transformations occur in everyday life, using an example from the street scene shown.

• A traffic light converts electrical energy into sound energy for pedestrian signals.
• Energy transformations occur when a car converts chemical energy from fuel into kinetic energy for movement, and then into thermal energy when braking.
• A bus changes thermal energy from the engine into chemical energy for fuel efficiency.
• A bicycle transforms kinetic energy into potential energy when going uphill.

Multiple Choice

• Light energy

Multiple Choice

Describe the difference between mechanical energy and elastic energy, providing examples for each.

• Mechanical energy is the total energy of motion and position, while elastic energy is the potential energy stored in elastic materials.
• Mechanical energy is the energy of heat and light, while elastic energy is the energy of sound.
• Mechanical energy is the energy stored in chemical bonds, while elastic energy is the energy of gravity.
• Mechanical energy is the energy of static objects, while elastic energy is the energy of thermal motion.
