Weight Analysis
Example Calculation
Weight on Mars Example
Earth weight: 75 kg
Mars gravity: 3.71 m/s² (vs Earth's 9.81 m/s²)
Formula: Weight_Mars = Weight_Earth Ă (g_Mars / g_Earth)
Calculation: 75 Ă (3.71 / 9.81) = 75 Ă 0.378 = 28.4 kg
Result: You would weigh 28.4 kg on Mars!
Why Weight Changes
⢠Mass stays the same - you don't lose matter
⢠Weight = Mass à Gravity - different gravity = different weight
⢠Larger planets generally have stronger gravity
⢠Distance from center also affects gravitational force
Gravity Facts
Sun
28Ă Earth's gravity - you'd weigh 28 times more!
Jupiter
2.5Ă Earth's gravity - heaviest planet to stand on
Moon
1/6 Earth's gravity - Apollo astronauts could jump 6Ă higher
Mars
38% Earth's gravity - perfect for superhuman leaps
Key Concepts
Mass vs Weight: Mass is constant, weight changes with gravity
Formula: Weight = Mass Ă Gravitational acceleration
Earth's gravity: 9.81 m/s² at sea level
Weightlessness: In space, you'd weigh 0 but keep your mass
Understanding Weight and Gravity
What is Weight?
Weight is the force exerted on an object due to gravity. Unlike mass, which remains constant throughout the universe, weight varies depending on the gravitational field strength of the celestial body you're on.
Why Weight Changes
- â˘Different planets have different masses and sizes
- â˘Gravitational force depends on mass and radius
- â˘Larger mass = stronger gravitational pull
- â˘Greater distance from center = weaker gravity
Physics Formula
W = m Ă g
Weight_planet = Weight_Earth Ă (g_planet / g_Earth)
- W: Weight (force in Newtons or mass in kg)
- m: Mass (constant value in kg)
- g: Gravitational acceleration (m/s²)
- g_Earth: 9.81 m/s² (standard)
Fun Fact: On the Moon, you could jump 6 times higher than on Earth because the gravitational pull is only 1/6 as strong!
