๐ŸงชLab Brief #57

Motion and Forces.

๐ŸŽฏ Your mission

Run the sim. Spot the pattern.

โšก The twist

Energy never disappears โ€” it just hides somewhere else.

๐Ÿคฏ

Mind = Blown

โšก Static electricity is the same physics as lightning, just smaller.

๐Ÿ”ฎ

Make a hypothesis first

Before you start: which will move faster, and why?

What You'll Learn

A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.

Key Words

  • inclined plane
  • wedge
  • screw

Steps

Step 1 โ€” Read

Read about Motion and Forces and write down three key facts.

Step 2 โ€” Do

Test friction: pull a weighted box across 4 surfaces (carpet, tile, sandpaper, foil). Use a spring scale to measure the force needed for each.

Step 3 โ€” Observe

Draw a detailed diagram of what you observe.

Step 4 โ€” Record

Write a conclusion: what did your results show? Did they match your prediction?

Question 1

1 of 3

What does Newton's third law state?

๐ŸŒ

Where you see this in real life

This is why airplanes can fly and why rockets reach space.

๐Ÿ†

Stretch Challenge

Try this in real life this week.

This week, find one thing in your house that turns one kind of energy into another.

๐Ÿ‘จโ€๐Ÿ‘ฉโ€๐Ÿ‘ง

For the dinner table

โ€œShow me something at home that uses this kind of energy.โ€
