Key Notes

🌀 What is Force?

• Force is a push or a pull on an object.
• It can make things start moving, stop moving, change direction, or change shape.

• Push – Moves something away from you.
  Example: Pushing a swing.
• Pull – Brings something toward you.
  Example: Pulling a door open.
• Gravity – A force that pulls everything down to the ground.
• Friction – A force that slows things down when they rub together.

⚡ What is Energy?

• Energy is what makes things move or work.
• We need energy to run, jump, play, and even think!

🔋 Types of Energy:

• Light Energy – Comes from the sun or bulbs.
• Heat Energy – Comes from fire, stoves, or the sun.
• Sound Energy – Comes from music, talking, or banging drums.
• Moving Energy (Kinetic) – Energy of moving things.

🔄 Force and Energy Work Together:

• When you kick a ball (force), the ball moves (uses energy).
• When you turn on a fan, electric energy turns into moving air.
