  • Trace transformations among translational kinetic, near-Earth gravitational potential and elastic potential energy stores.
  • Use conservation of mechanical energy to calculate speeds, heights or elastic-energy changes and identify dissipative transfers where present.

IB Physics SL A 3 8 Mechanical Energy Transformations Questions question 1

[Maximum number: 2]

An elastic climbing rope is tested by fixing one end of the rope to the top of a crane. The other end of the rope is connected to a block which is initially at position A. The block is released from rest. The mass of the rope is negligible.
