Momentum and Collisions (Part 3).

๐ŸŽฏ Your mission

Master the concept. Use it tomorrow.

โšก The twist

Nature loves to surprise the careful watcher.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฌ The more you look, the more nature shows you.

๐Ÿ”ฎ

Make a hypothesis first

Before you start: write down what you think will happen, and why.

What You'll Learn

Momentum is mass times velocity. A heavy truck moving slowly can have the same momentum as a light car moving fast. Momentum is conserved in collisions.

Key Words

  • circuit
  • voltage
  • current

Steps

Step 1 โ€” Read
