"Skillful Use of Inclined Planes" Architecture and Simple Machinery PPT Courseware

How to move these large oil drums into the car?

A simple machine like a wooden plank stretched over a car cabin is called an incline.

1. Explore the role of inclined planes

Experimental materials: Incline, dynamometer, different weights.

Experimental steps: 1. Set up the slope.

2. First measure the force that directly lifts the object, then measure the force that lifts the object along the incline, and record it.

3. Change the weight of the object and repeat step 2.

4. Discuss and organize experimental findings.

Condition to change: weight of object

Conditions that do not change: the size of the slope of the slope

Kind tips:

1. Use the dynamometer correctly.

2. The group leader coordinates everyone's experiments. During the operation, each student operates once and rotates in order to ensure that everyone participates and everyone gains something.

3. Arrange a recorder to record while doing the experiment.

2. Study slopes with different slopes

Experimental steps:

1. First measure the force that directly lifts the object.

2. Then measure the force of lifting the object along different inclines.

3. Discuss and organize experimental findings.

Conditions to be changed: size of slope slope

Condition that does not change: the weight of the object

3. Application of inclined planes in life

Talk about why the winding mountain road is built into an "S" shape?

Highway approach bridge

slope on steps

Thinking: When a person encounters an uphill slope while riding a bicycle, how can he ride with less effort?
