Question

a catapults lever holds a cannonball. the lever is attached to a tightly held rope. when the rope is released, the lever springs forward and launches the cannonball. when the rope is held tightly, which form of energy does it possess?
○ thermal
○ nuclear
○ gravitational
○ elastic

Explanation:

Elastic energy is the energy stored in objects that are compressed or stretched. In this case, the rope is held tightly, which means it is stretched. Thermal energy is related to heat, nuclear energy is from atomic reactions, and gravitational energy is due to an object's height in a gravitational field. Since the rope is stretched (a form of elastic deformation), it has elastic energy.

Answer:

elastic
