Magnetic Fields 1.2

Open Ended

Describe a situation where understanding magnetic fields could be useful in everyday life.

Open Ended

What are the different ways a magnet can move an object?

Multiple Choice

Which of the following is a possible reason why a magnetic launcher can move a spacecraft without touching it?

• Magnetic force acts at a distance

• Gravity pulls the spacecraft

• Friction between launcher and spacecraft

• Air pressure pushes the spacecraft

Open Ended

Why do you think the spacecraft’s speed was different on the Monday, Tuesday, and Wednesday launches?

Fill in the Blanks

On Wednesday, the spacecraft traveled

m/s, which was 30 m/s faster than expected.

Open Ended

How did changing the distance between the spacecraft and the launcher affect the speed of the spacecraft over the three days?

Multiple Choice

What was the target speed for the model spacecraft, and on which day did it exceed this speed?

• 80 m/s, Monday

• 90 m/s, Tuesday

• 120 m/s, Wednesday

• 100 m/s, Tuesday

Poll

Which of the following claims could explain why the spacecraft went much faster than expected on Wednesday?

• The magnets were misaligned on Tuesday.

• Much more energy was in the launcher system on Wednesday than on Tuesday.

• The magnetic force was much stronger on Wednesday than on Tuesday.

• The spacecraft was lighter on Wednesday.
