Question

5.1. Астронавт здійснив подорож із Землі на місяць. У скільки разів відрізняють ся маса й вага астронавта на Місяці та на Землі, якщо прискорення вільного Н падіння на поверхні Місяця дорівнює 1,6 а на поверхні Землі - 9,8 ​

Answer 1

Ответ:

6,125

Объяснение:

P = mg

P1 = 1,6 * m

P2 = 9,8 * m

P2/P1 = P∆

P∆ = 9,8/1,6 = 6,125

Answer 2

Difference in Mass and Weight of an Astronaut on the Moon and Earth

When an astronaut travels from Earth to the Moon, their mass remains the same, but their weight changes due to the difference in gravitational acceleration on the Moon compared to Earth.

Mass vs. Weight: - Mass refers to the amount of matter in an object and is measured in kilograms (kg). - Weight is the force exerted on an object due to gravity and is measured in newtons (N).

Calculation: The gravitational acceleration on the surface of the Moon is approximately 1.6 m/s^2, while on the surface of the Earth, it is approximately 9.8 m/s^2.

The relationship between mass, weight, and gravitational acceleration is given by the formula: \[ \text{Weight} = \text{Mass} \times \text{Gravitational Acceleration} \]

On the Moon: - The gravitational acceleration on the Moon is 1.6 m/s^2. - Therefore, an astronaut's weight on the Moon would be approximately 1/6th (or 16.3%) of their weight on Earth.

On Earth: - The gravitational acceleration on Earth is 9.8 m/s^2. - Therefore, an astronaut's weight on Earth would be approximately 6 times (or 600%) their weight on the Moon.

This means that an astronaut's weight on the Moon is significantly less than their weight on Earth due to the lower gravitational acceleration on the Moon.
