Question

If snowmen destruction is like skater injuries on our ramp, how can you use what you learned from the Gizmo to design a safer ramp? (Use words like mass or height, more or less, and describe how you would make

Answer 1

Think of the snowmen falling in the Gizmo as skaters falling off your ramp. The same physics apply: heavier riders or higher drops give more energy to cause damage. Use those ideas to make the ramp safer:

Short, plain explanation
- Potential energy ∝ m·g·h. Less height (h) means less energy to convert to speed → less severe impacts.
- Kinetic energy ∝ 1/2 m v^2 and momentum p = m v. Lower speed (v) or less mass (m) reduces the energy/force in a crash.
- Average impact force ≈ change in momentum divided by stopping time. Increasing stopping time or distance reduces force.

Specific design changes (use more/less)
- Make the starting platform lower (less height) and the slope gentler (less steep). That gives riders less speed and energy.
- Lengthen the ramp/run-out (more length) so acceleration is spread out and braking can be gradual.
- Reduce big vertical drops and sharp transitions (use more gradual radii) so riders don’t convert height into sudden vertical impacts.
- Add energy-absorbing surfaces and padding at likely impact zones (more padding, foam, crash mats) so stopping time is longer and forces are smaller.
- Increase controlled friction where appropriate (more grip) to reduce sliding speed, but keep transitions smooth to avoid abrupt stops.
- Create beginner lines with lower height and gentler slopes (more lanes of different difficulty) so lighter/less-skilled riders use lower-risk features.
- Remove hard edges and obstacles (less exposure to sharp impacts); increase clear run-out area so riders can slow safely.

Optional operational controls
- Limit allowed speeds or require protective gear (helmets, pads) so effective injury risk is lower even for larger mass.
- Post weight/skill guidelines so very heavy riders use gentler lines (less mass → less momentum).

Putting it together: make the ramp lower and less steep, increase ramp length and run-out, smooth transitions, and add more padding and energy-absorbing surfaces. These changes reduce the height-to-speed conversion and increase stopping time, which together reduce the forces that cause injuries.
