Lesson 30 of 84 ยท Motion and Forces
Simulationโญ 30 XPโก Spark LabThe Wheel and Axle
Motion and Forces.
๐ฏ Your mission
Run the sim. Spot the pattern.
โก The twist
Energy never disappears โ it just hides somewhere else.
Mind = Blown
โก Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.
Key Words
- screw
- wheel and axle
Steps
Study the diagram and label the parts you recognize.
Build a simple motor using a battery, magnet, wire, and paper clip supports. Observe how electromagnetic forces create rotation.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
Check Your Understanding
Question 1
1 of 3What does friction do?
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
โShow me something at home that uses this kind of energy.โ
