Cliffside Rescue

A class game. You run the winch. Every choice is a vote.
How it works

How hard should the winch pull?

↓
Gravity pulls the load down. That's its weight.
↑
The winch pulls it up. You choose how hard.
✂
Every cable has a limit. Pull harder than that and it snaps.
4
4 rescues. The load, the cable and the weather change each time.
Hands up for each option. The most hands wins.
Mission report

Pull more than the weight → it rises
The difference is the net force. A bigger net force means it speeds up faster.
Every resource has a limit
A stronger pull isn't always better. Past the cable's limit, you lose the very thing you depend on.
Pull less than the weight → it comes down
A little less lowers it gently. Far too little and it crashes.
Newton's second law: net force = mass × acceleration. Here: pull − weight = mass × acceleration.
What do you have that can lift someone?
And what are your limits?
Pull too little and nothing moves. Pull past your limit and something breaks.
