"The Secret of Pendulum" PPT

Part One: Problem Exploration

Moving ships, soaring planes, Mercedes-Benz cars, flying bullets, glowing lights, heating boilers... Any object requires energy to work and releases energy at the same time. Energy is everywhere and everywhere. In nature, energy exists in many forms, such as mechanical energy, electrical energy, light energy, thermal energy, sound energy, magnetic energy, electromagnetic energy, chemical energy, etc. However, where does this energy come from and where does it go? How do various energies transform into each other? Let us enter the world of energy together, explore its mysteries, and uncover the doubts in our hearts.

Make a pendulum and study its secrets

When the pendulum is swinging, swinging out and then swinging back is called a swing.

Part 2: Practice

1 About 400 years ago, Italian scientists ______ discovered the secret of the pendulum.

2 The following statement is correct ( ).

A． The same pendulum swings at irregular speeds.

B. How fast or slow the pendulum swings depends on the length of the cycloid.

C. The weight of the pendulum has a great influence on how fast it swings.

3. Let’s talk about a pendulum-like phenomenon in life.

4. Do you know the story of Galileo’s study of the pendulum? Check out the profile to learn more about him.

5. Think about why the pendulum we made slowly stops? And the pendulum of a pendulum clock can swing for a long, long time?

An ordinary pendulum will slowly stop due to energy loss due to friction and air resistance. Although the pendulum of a pendulum clock is also affected by friction and air resistance, we wind it regularly and store potential energy. (Elastic potential energy) supplements the energy loss of the pendulum, so the pendulum of a pendulum clock can swing for a long time.
