Kinetic Energy: Energy in Motion (Part 2).

๐ŸŽฏ Your mission

Play with the model. Break it. Understand it.

โšก The twist

The opposite of what you expect is often what happens.

๐Ÿคฏ

Mind = Blown

๐ŸŽข You feel weightless on a roller coaster because you and the seat are falling at the same speed.

๐Ÿ”ฎ

Make a hypothesis first

Predict: what happens if you double the force?

What You'll Learn

Kinetic energy is the energy of motion. A moving car, a rolling ball, and a flying bird all have kinetic energy. The faster an object moves, the more kinetic energy it has.

Key Words

  • velocity
  • force

Steps

Step 1 โ€” Read

Review the background information on Energy before starting.

Step 2 โ€” Do

Build a simple circuit using a battery, wire, and light bulb. Then add a switch and test what happens when you open and close it.

Step 3 โ€” Observe

Watch carefully for any changes and note the time.

Step 4 โ€” Record

Create a data table to organize your measurements.

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€
