Kinetic Energy: Energy in Motion (Part 3).

๐ŸŽฏ Your mission

Learn the rule. Then catch nature using it.

โšก The twist

Speed isn't the same as force. Don't mix them up.

๐Ÿคฏ

Mind = Blown

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

๐Ÿ”ฎ

Make a hypothesis first

Guess: where does the energy go?

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
  • Newton

Steps

Step 1 โ€” Read

Review the background information on Forces 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.

Question 1

1 of 3

What type of energy does a moving object have?

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€
