Question

Какова природа силы, которая действует на тело , висящее на динамометре.

Answer 1

На тело висящее на динамометре действует сила тяжести, которая имеет гравитационную природу. А при скольжении по дереву действует сила трения, которая имеет электромагнитную природу.

Answer 2

The Nature of the Force Acting on a Body Hanging on a Dynamometer

When a body is hanging on a dynamometer, the force acting on it is the force of gravity. This force is commonly referred to as the weight of the body. The weight of an object is the force with which it is pulled toward the center of the Earth by gravity. The weight of an object depends on its mass and the acceleration due to gravity.

The force of gravity can be defined as follows: - The force of gravity is the attractive force between two objects with mass. In this case, the two objects are the Earth and the body hanging on the dynamometer. - The force of gravity always acts vertically downward, toward the center of the Earth. - The magnitude of the force of gravity depends on the mass of the body and the acceleration due to gravity.

The force of gravity can be calculated using the following formula: - Force of gravity (F) = mass (m) × acceleration due to gravity (g)

The acceleration due to gravity is approximately 9.8 m/s² on the surface of the Earth. Therefore, the force of gravity on a body hanging on a dynamometer can be calculated by multiplying its mass by 9.8 m/s².

It's important to note that the reading on the dynamometer will indicate the magnitude of the force of gravity acting on the body. The dynamometer measures the tension in the string or spring connected to the body and converts it into a force reading.

In summary: - The force acting on a body hanging on a dynamometer is the force of gravity. - The force of gravity is the weight of the body, which depends on its mass and the acceleration due to gravity. - The dynamometer measures the tension in the string or spring connected to the body and converts it into a force reading.
