What parts does a spring dynamometer consist of?

When using a spring dynamometer, please note:

1. Pick up the dynamometer (lifting ring) and first check whether the pointer is pointing at the "0" position. (zero adjustment)

2. When reading, keep your sight level with the pointer.

3. The measured force cannot exceed the measuring range of the dynamometer. If the pointer has reached the maximum value and the weight has not been lifted, the measurement should be stopped or a dynamometer with a larger measurement range should be used instead.

4. When measuring force, lift the object slowly and do not use excessive force.

I will fill in

1. “N” in the picture means _______.

2. The spring dynamometer is mainly composed of _______, _______, _______, _______, _______, etc.

3. When using a spring dynamometer, does it need to be zeroed? _______.

4. Can the force of 10N be measured using the spring scale as shown in the picture?

5. People are accustomed to using _____ and _____ to express the magnitude of gravity and other forces in daily life. In science and technology, it is uniformly stipulated that the unit of force is _____, referred to as _____.

6. When using a spring dynamometer to measure gravity, pick up the dynamometer and first check whether the pointer is pointing to the "_____" position. When reading, the line of sight and the pointer are _____. The force measured cannot exceed the amount of _____ marked on the dynamometer.

Make a rubber band dynamometer

Materials: paper clips, cardboard, rubber bands

step:

1. Fix one end of the rubber band to the lifting rope, and use an iron wire as a hook on the other end.

2. Lift the dynamometer and mark the "0" scale.

Thinking: How to correctly draw the scale of a rubber band dynamometer?

What is elasticity?

When objects are acted upon by external forces, their shapes are easily changed. When their shapes change, they will generate a force to restore their original shape. This force is called elasticity.

The greater the force, the longer it stretches..
