Question

gravity data table
name
gravity is the force that pulls objects toward the center of a planet. the strength of gravity varies from planet to planet based on the planets mass and size.
in the table the weight of a 10 - kilogram object changes on different planets due to their varying gravity.
note: the data in the table represents the gravity in meters per second squared of each planet and calculations for the mass of a 10 - kilogram object and its weight in newtons on each planet.
1.which planets gravity is very similar to earth?
2.how does the gravity on jupiter compare to the gravity on earth?
3.why would an object weigh more on neptune compared to mars, even if they have the same mass?
4.explain how the gravity on a planet influences the weight of an object on that planet. use specific examples from the data provided.
5.how does the gravity on mars impact the way astronauts would move and work on the surface of the planet compared to earth?

Explanation:

1. By comparing the gravity values in the table, Venus has a gravity of 8.87 m/s² which is close to Earth's 9.81 m/s².
2. Jupiter's gravity is 24.79 m/s² while Earth's is 9.81 m/s². So Jupiter has much stronger gravity.
3. Weight is calculated by \(W = mg\) (where \(W\) is weight, \(m\) is mass and \(g\) is gravity). Neptune has a higher gravity (11.15 m/s²) than Mars (3.71 m/s²), so for the same mass, the object weighs more on Neptune.
4. Weight \(W = mg\). For example, on Earth with \(g = 9.81\ m/s²\) and \(m = 10\ kg\), \(W=10\times9.81 = 98.1\ N\). On Mercury with \(g = 3.7\ m/s²\) and \(m = 10\ kg\), \(W = 10\times3.7=37\ N\). Higher gravity leads to higher weight for the same - mass object.
5. Mars has a lower gravity (3.71 m/s²) compared to Earth (9.81 m/s²). Astronauts would move more freely and with less effort on Mars, as they would feel lighter and have less downward - pulling force acting on them.

Answer:

1. Venus
2. Jupiter has much stronger gravity than Earth.
3. Because Neptune has a higher gravitational acceleration than Mars.
4. Weight is directly proportional to gravity (\(W = mg\)). Higher gravity means higher weight for the same mass object. For example, a 10 - kg object weighs 98.1 N on Earth and 37 N on Mercury.
5. Astronauts would move more freely and with less effort on Mars as the lower gravity makes them feel lighter.
