Question

Маса астронавта,що перебуває на Землі,складає 80 кг.Якою буде його вага на Землі?На Місяці? У космічному кораблі під час польоту при вимкнутих двигунах? Яка маса астронавта на Місяці

Answer 1

На землі 800Н. На місяці 160Н. На кораблі 0Н. Маса на місяці 16КГ.

Answer 2

Weight of an Astronaut on Earth

The weight of an astronaut on Earth is equal to their mass multiplied by the acceleration due to gravity on Earth. The acceleration due to gravity on Earth is approximately 9.8 m/s^2.

Given that the mass of the astronaut is 80 kg, we can calculate their weight on Earth using the formula:

Weight = Mass x Acceleration due to Gravity

Weight on Earth = 80 kg x 9.8 m/s^2

The weight of the astronaut on Earth would be approximately 784 Newtons.

Weight of an Astronaut on the Moon

The weight of an astronaut on the Moon is different from their weight on Earth because the Moon has a lower gravitational force compared to Earth. The acceleration due to gravity on the Moon is approximately 1/6th of that on Earth, which is about 1.6 m/s^2.

To calculate the weight of the astronaut on the Moon, we can use the same formula as before:

Weight on Moon = Mass x Acceleration due to Gravity

Weight on Moon = 80 kg x 1.6 m/s^2

The weight of the astronaut on the Moon would be approximately 128 Newtons.

Weight of an Astronaut in a Spaceship with Engines Off

In a spaceship with the engines off, the astronaut would experience weightlessness. Weightlessness occurs when there is no external force acting on an object to counteract the force of gravity. In this state, the astronaut would feel as if they have no weight.

However, it is important to note that the mass of the astronaut remains the same regardless of the presence or absence of gravity. So, the mass of the astronaut would still be 80 kg in the spaceship.

Mass of an Astronaut on the Moon

The mass of an object remains the same regardless of its location. Therefore, the mass of the astronaut would still be 80 kg on the Moon.
