"Prove that the Earth is Rotating" Earth's Movement PPT Courseware

Small experiment:

Experimental steps:

1. Use the iron stand as a support and hang a pendulum on it.

2. Place the iron stand and pendulum on a round base. First let the pendulum swing back and forth, and then slowly and steadily rotate the circular chassis.

Precautions:

The pendulum should be slightly heavier, do not shake the table, do not let the wind blow the pendulum, do not swing too much, etc. Teachers and students observed carefully and filled in the experimental record sheets.

test you:

1. If a huge pendulum is erected on the surface of the earth, and the earth's disk does not move, what will happen after it swings?

2. What phenomena will you see when the earth's disk rotates? What does it mean?

The phenomenon of earth rotation in daily life:

1. The rotation of the earth produces the phenomenon of day and night alternation, resulting in the phenomenon of differences in time in different places.

2. The train wears the two rails differently.

3. An iron ball is dropped freely from a very high tower. It is found that the direction of its fall is always eastward.

4. Fallen leaves always spin and fall.

Although the Earth's rotation cannot be directly observed, it can still be confirmed through experiments.

Bravely overcome difficulties:

An artilleryman always aims his artillery shells directly at the target when practicing long-distance shooting, but misses every time. What do you think is going on? Can you help him?
