Question

1. mark constructed a mousetrap car for a science project. when the mousetrap was pulled back and set, it had a lot of tension built up.

potential energy
kinetic energy

Explanation:

Potential energy is stored energy due to position or condition. When the mousetrap is pulled back and set, the tension (stored energy) is potential energy. Kinetic energy is energy of motion, which isn't the case here as the trap is set (not moving). So the energy here is potential energy.

Answer:

POTENTIAL ENERGY
