Demonstration 1
Resolving forces of a ladder against a wall. Place the bottom of the ladder against a fixed mark, with a set of scales underneath the ladder and the PASCO pressure sensor against the fixed point. Another set of scales should be on the wall on which the ladder leans. Someone climbs half way up the ladder and measurements are taken.
Resources
Analysis
Resolve the components of the forces acting on the ladder.
Equipment
2x scales, 1x PASCO pressure sensor kit & 1x ladder
Safety
Make sure the ladder cannot slip and that there is always someone holding the bottom of the ladder.
