Question

Use the table of information from an investigation to answer the question.

Electromagnets Ordered by Magnetic Force Strength
Student Depth of Object in Sand (cm)
Maddie 1.8
Naveed 4.0
Two students drop an object into sand from a height of 1.5 meters. They record the depth of the hole made in the sand by each student’s object. What is the most likely explanation for the results?

Maddie’s object has a smaller width.

Naveed’s object has less mass.
Naveed’s object has less mass.

Maddie’s object had a faster drop speed.

Answer 1

Naveed’s object had greater kinetic energy.

Explanation: Both objects were dropped from the same height, so they hit the sand at the same speed. The deeper hole (4.0 cm vs 1.8 cm) therefore means Naveed’s object had more kinetic energy on impact — most likely because it had more mass.
