"Measuring the Size of Force" Motion and Force PPT

Part 1: Understanding the spring dynamometer

In-depth study of motion and force often requires knowing the size of force. A spring dynamometer is a tool for measuring force. It is often called a spring balance in life.

Pull the spring hard and slowly and observe the change in the shape of the spring. As the tension slowly decreases, the shape of the spring changes. Try to explain why a spring dynamometer can measure force.

The spring dynamometer uses the characteristics of the spring "large force and long elongation" to measure the force.

People are accustomed to using "gram" and "kilogram" 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 "Newton", which is referred to as "Niu" and is represented by "N".

1 Newton ≈ 100 grams of force.

Measuring force PPT, Part 2: Measuring force with spring dynamometer

When using a spring dynamometer to measure gravity, please note:

1. Pick up the dynamometer and first check whether the pointer is pointing at the "0" position.

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

3. The measured force cannot exceed the measuring range of the dynamometer.

When measuring force, lift the object slowly and do not use excessive force. If the pointer has reached the maximum value and the weight has not been lifted yet, the measurement should be stopped or a dynamometer with a larger measuring range should be used instead.

Measuring force PPT, part three: homemade dynamometer

We can make a dynamometer out of rubber bands, cardboard, and paper clips.

Give it a try: What difference would there be between a dynamometer made using the two methods below?

How to correctly draw the scales of these two dynamometers?

Use hook codes or hang objects of known weight to correctly draw the force scale on the dynamometer cardboard.
