I don't think you understand the GRAVITY of how lucky we are to find a helicopter.
This experiment starting from this helicopter will use all forces: Gravity, Elaticity, Magnatism, and Friction.
Ryan is going to drop the ball. It is going to reach terminal velocity. Then it will reach the ground and bounce of a tranpoliene. Sfter the ball bounce on the trampolien, Ryan will put a strong magnite under the tranpolien. The ball is magnetic material inside. The ball shouldn't bounce as much anymore becuase the magnet is pulling the ball constantly down.
Owww!!! That object had a hard force.
The ball was dropped. Gravity is now pulling it down. Howerver, as the ball goes faster, the friction (Fluid Friction) is increasing. SO the garavity and friction is equal. The ball is at terminal velocity.
Wow this is really a MAGNETIC experiment
The trampoline is elastic so it bends back creating a upward force that bounces the ball up.
The magnet is is placed as the ball is about to stop ocvercoming garcity and fall back down again.
