Speed, Velocity, and Acceleration

๐ŸงชLab Brief #15

Speed, Velocity, and Acceleration.

๐ŸŽฏ Your mission

Master the concept. Use it tomorrow.

โšก The twist

The opposite of what you expect is often what happens.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฅ A bolt of lightning is 5 times hotter than the surface of the sun.

๐Ÿ”ฎ

Make a hypothesis first

Predict: what happens if you double the force?

What You'll Learn

Speed measures how fast an object moves (distance divided by time). Velocity includes both speed and direction. An object changing direction is accelerating even at constant speed.

Key Words

  • kinetic
  • potential

Steps

Step 1 โ€” Read

Step 4 โ€” Record

Record your observations in your science journal with measurements and descriptions.
