Question

На пружине висит шар массой m=250 г. Чему равны сила упругости и сила тяжести, действующие на шар? Изобразите их в тетради стрелками (масштаб: 1 клетка - 0,50 H)

Answer 1

Fт=Fупр=mg=0,25 кг (250 г) ×10 Н/кг=2,5 Н

Answer 2

Forces Acting on the Spring-Hanging Mass

When a spring is hanging vertically with a mass attached to it, two main forces act on the mass: the force of gravity and the force of the spring.

Force of Gravity (Weight): The force of gravity acting on the mass can be calculated using the formula: \[ F_{\text{gravity}} = m \times g \] where \( m = 250 \, \text{g} = 0.25 \, \text{kg} \) (mass of the object) and \( g = 9.81 \, \text{m/s}^2 \) (acceleration due to gravity).

Force of Spring (Elastic Force): The force exerted by the spring can be calculated using Hooke's Law: \[ F_{\text{spring}} = k \times x \] where \( k \) is the spring constant and \( x \) is the displacement from the equilibrium position.

Since the displacement is not given, we can't calculate the exact force of the spring without knowing the spring constant or the displacement.

Diagram Representation

To represent these forces in a diagram, we can use arrows to indicate the direction and magnitude of the forces. Given that 1 cell = 0.50 H, we can represent the forces in the following way:

- Force of Gravity (Weight): - Arrow pointing downwards with a length representing the force magnitude.

- Force of Spring (Elastic Force): - Arrow pointing upwards with a length representing the force magnitude.

Unfortunately, without the specific values for the spring constant and the displacement, we can't accurately represent the forces in the diagram.

If you have the specific values for the spring constant and the displacement, I can help you calculate the force of the spring and represent the forces in the diagram accordingly.
