Tell about Hooke’s law according to the following plan: connection between physical quantities, writing the law in the form of a formula, body rigidity, units of rigidity.
In elastic compression or tension, the elastic force is equal in modulus to the force of gravity. The greater the body weight, the longer the cord stretches and the greater the elastic force. Fupr = -kh Hooke’s law. The elastic force arising from elastic deformation of a body is proportional to the elongation (or compression) of the body. The stiffness to the spring depends on the size of the spring and on the material from which it is made. In SI, the stiffness is expressed in N / m.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
