8.3 Lesson Set 1 Review Flashcard

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, often resulting in a change in the state or motion of the objects involved.

Front

What evidence indicates energy transfer between a magnet and a coil?

Back

The most reliable evidence is if either the magnet or the coil moves.

Front

How can you determine if a magnet interacts with a coil without contact?

Back

By holding the magnet close to the coil without letting them touch.

Front

What indicates that energy has been transferred to an object?

Back

The object moves.

Front

What happens in the space between magnets when they interact?

Back

Energy is transferred through magnetic fields.

Front

Is a compass needle a permanent magnet? Why?

Back

Yes, because it always points north, indicating it has a consistent magnetic field.

Front

What is a magnetic field?

Back

A magnetic field is an invisible field around a magnet where magnetic forces can be felt.

Front

What is the role of motion in energy transfer?

Back

Motion is often a key indicator that energy has been transferred, as it shows a change in position or state.

Front

What is the difference between permanent and temporary magnets?

Back

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in the presence of a magnetic field.

Front

What is an example of energy transfer in everyday life?

Back

When you rub your hands together, mechanical energy is converted into thermal energy, warming your hands.
