Energy Changes in Magnet Simulations

Mr. Kirk introduces lesson 2.3, focusing on simulating energy changes using magnets. The lesson skips the warm-up and dives into activity 2, where students explore how potential energy converts to kinetic energy when magnets repel. The main investigation question is how a system of magnets stores potential energy in a magnetic field. Students use a simulator to evaluate two claims about potential energy changes when magnets move with or against magnetic forces. The lesson concludes with expectations for students to fill in their observations and justify their thoughts.

What is the main focus of the lesson introduced by Mr. Kirk?

• The construction of magnets

• The history of magnets

• Simulating energy changes between potential and kinetic energy

• The chemical properties of magnets

In the simulation, what happens to potential energy as two magnets repel each other?

• It increases

• It converts into kinetic energy

• It remains constant

• It disappears

What relationship is explored between kinetic energy and the speed of objects in the simulation?

• Kinetic energy increases as speed increases

• Kinetic energy remains constant regardless of speed

• Kinetic energy decreases as speed increases

• Kinetic energy is unrelated to speed

How does the distance between magnets affect the conversion of potential energy?

• Closer magnets have weaker fields

• Farther magnets have stronger fields

• Distance does not affect the fields

• Closer magnets have stronger fields

What is the main investigation question posed in the lesson?

• How does a system of magnets store potential energy in a magnetic field?

• How do magnets lose energy?

• How do magnets create electricity?

• What is the speed of light in a magnetic field?

According to Claim A, when does potential energy increase?

• When a magnet is stationary

• When a magnet is moved against the magnetic force

• When a magnet is heated

• When a magnet is moved with the magnetic force

What feature in the simulator allows you to lock objects in place?

• The scrubber feature

• The lock feature

• The rotate feature

• The analyze feature

What is the purpose of the 'scrubber' in the simulator?

• To adjust the speed of the simulation

• To change the color of the magnets

• To clean the simulation screen

• To drag back and forth to analyze energy changes

What should students do after completing the experiments with the simulator?

• Write a report on magnet history

• Submit their findings and justify their thoughts

• Ignore the results

• Create a new simulation

Which section of the lesson are students instructed to skip?

• Section 4

• Section 3

• Section 1

• Section 2
