Part One Content: Classroom Experiment

experiment equipment:

bevel

Iron platform

Dynamometer

car

Use of dynamometer

Observe its measuring range, recognize its graduation value, and choose a suitable spring dynamometer (the weight of the object cannot exceed the measuring range).

Before use, check whether the pointer of the spring dynamometer points to the zero position.

When reading, the line of sight should be at the same level as the spring dynamometer indication (be careful not to hang the object for too long, otherwise the dynamometer will be damaged).

Experimental Note:

On the inclined surface, the dynamometer should be as parallel as possible to the inclined surface, and pull it up slowly and at a constant speed.

Part 2: Our conclusions

Using an inclined surface saves effort.

When the height is the same, the longer the slope, the less effort it takes.
