Description

"Our Little Cable Car" Movement and Force PPT Courseware 2

What power do they rely on to move?

To make a vehicle move, it must be given a force - power.

1. Installation

2. Verify and record:

How much force is needed to make a stationary car move?

3. After the experiment is completed, quickly put the items back to their original places and tell the teacher with an upright posture.

On the earth, due to the effect of the earth's gravity, all objects are subject to a vertical downward force, which is gravity.

Gravity is the force exerted on objects due to the attraction of the Earth. When we carry water, we feel the downward pull of the bucket on our hands; when we carry a schoolbag, we feel the downward pressure of the schoolbag on our shoulders. Objects are subject to a downward force, which is gravity.

The apples on the tree fall down, the ball thrown upward will eventually fall back to the ground, we slide down the slide, the water flows down... these movements are all due to the action of gravity.

Experiment summary:

The gravitational pull of the paper clip on the rope causes the car to move.

Kind tips:

(1) Control the distance of the car. Each experiment starts with the transparent tape and ends with the edge of the table.

(2) Add iron washers three by three, observe how the speed of the car changes, and record the time.

(3) The team should have a clear division of labor: two people should be identified as operators (one person controls the trolley and one person places the iron washer), one person should be the recorder, and the other person should be the commander and timekeeper. The operator must listen to the command of the commander (call "release," stop").

(4) After the experiment is completed, quickly put the items back on the plate and tell the teacher with an upright posture.

Our conclusion: The more paper clips, the greater the pulling force generated and the faster the car moves.

Let me try: If we give this small cable car a pull, it will start to move. Can we think of a way to save some effort and let it move on its own?

1. When we carry water, we feel the downward pull of the bucket on our hands; when we carry a schoolbag, we feel the downward pressure of the schoolbag on our shoulders. Objects have a downward force, which is _____.

2. In the car experiment, the more washers there are, the more _____ the car moves.

3. In this experiment, the magnitude of the pulling force is related to __________.

4. When the weight pulling the trolley becomes heavier, the speed of the trolley movement ( ).

A. Faster B. Slower C. Not necessarily

5. When the pulling force is large, the movement speed of the small cable car ( ).

A. Getting faster and faster B. Getting slower and slower C. Staying the same

6. Put the car on the slope and the car slides down. This is because ( ).

A. The car is affected by gravity

B. There is a force pushing the car down

C. It is the force of the wheels that makes the car slide down
