Speed, Velocity, and Acceleration (Part 2).
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.
Make a hypothesis first
Before you start: which will move faster, and why?
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
- circuit
- voltage
- current
Steps
Study the diagram and label the parts you recognize.
Create a Rube Goldberg machine with at least 5 steps that demonstrates energy transfer from one form to another.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.
Check Your Understanding
Question 1
1 of 3What is velocity?
Where you see this in real life
You use this every time you flip a light switch, ride a bike, or kick a ball.
Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
