What is Physics?

Mr. Anderson introduces physics, tracing its roots from ancient times to the Scientific Revolution. He discusses Galileo's contributions to mechanics and pendulums, and explains Newton's three laws of motion. The video contrasts classical mechanics with modern physics, highlighting the limitations of Newtonian physics at atomic and high-speed levels. It also covers the broad scope of physics, including thermodynamics, electromagnetism, and quantum theory, emphasizing physics as a tool to understand the world.

What is the origin of the word 'physics'?

• German word 'physik'

• Latin word 'physica'

• Greek word 'phusis'

• French word 'physique'

Which of the following did Galileo NOT study?

• Telescopes

• Pendulums

• Electromagnetism

• Kinematics

According to Newton's first law, what happens to an object at rest?

• It stays at rest

• It starts moving

• It changes direction

• It accelerates

What does Newton's second law state about force and acceleration?
