Description
"Our Little Cable Car" Movement and Power PPT Download
Part One: Hands-on Practice
Install a small cable car
Experimental purpose: Install a small cable car
Experimental equipment: car body, wheels, washers, wires
Experimental steps: 1. Provide materials; 2. Install the car; 3. Let the car move.
Experimental requirements: Make the stationary car move
Install a small cable car as shown in the picture
consider:
Is the position of the string tied to the car related to the direction of the car's movement?
How to prevent the car from falling?
What role does the iron washer play?
How much force is needed to make the car move?
Only when the rope is tied at the right position, usually in the center of the front of the car, can the direction of the pulling force be consistent with the direction of the wheel rolling forward, otherwise the car will go astray.
When we carry water, we feel a downward pull; when we carry a backpack, we feel a downward pressure. Objects all experience a downward force, which is gravity.
Our small cable car PPT, the second part: expansion and extension
Force is the interaction between objects. To put it figuratively, force is the effect of "push" and "pull". The concept of force was originally abstracted from the sensation of the human body exerting force to tense muscles.
Newton - a great British physicist, mathematician, astronomer, and the founder of the classical mechanics system.
Our small cable car PPT, the third part of the content: Summary of this lesson
Gravity is the downward pulling force that an object receives due to the attraction of the earth. A certain pulling force can make a stationary car move. The greater the pulling force, the faster the car moves.
Our small cable car PPT, part 4 content: Classroom exercises
1. Fill in the blanks
1. ( ) is the downward pulling force that an object receives due to the attraction of the earth.
2. A certain pulling force can make a stationary car move. The greater the pulling force, the farther the car moves ( ).
2. Judgment
1. Gravity has nothing to do with pulling force and cannot determine the movement of the car. ( )
2. Force is the interaction between objects. ( )
3. When we carry water, we feel the downward pull of the bucket on our hands; when we carry a backpack, we feel the downward pressure of the book on our shoulders. This is all because the object is affected by gravity. ( )
Our little cable car PPT, part 5: homework
Look up the information and explain what various means of transportation rely on as power to move.
