I am having trouble rationalising the fact that the moons gravity is a fraction of the Earth's and is far out in space, but still manages to out pull the Earth's gravity albeit a tiny amount and create tides?
chis said:Thanks guys, is the assumption that gravity travels in waves and if so is there evidence of reinforcement or canellation. Hence my original question should the opposing gravity waves result in the Moons being totaly canceled out before reaching Earth.
Gravity is a force that exists between any two objects with mass, pulling them towards each other. Tides, on the other hand, are the rise and fall of sea levels caused by the gravitational pull of the moon and sun on the Earth's oceans.
People may confuse gravity and tides because both involve the concept of gravitational force. However, the force of gravity is a universal force that affects all objects, while tides are specific to the Earth's oceans.
Yes, tides can affect gravity in a very small way. The gravitational pull of the moon and sun on the Earth's oceans causes the water to bulge, which in turn creates additional gravitational pull. However, this effect is very small and does not significantly impact the overall force of gravity.
Gravity is essential for keeping the Earth and other planets in orbit around the sun, and for holding our atmosphere in place. Tides play a crucial role in the Earth's ecosystem, influencing ocean currents and providing nutrients for marine life.
Yes, both gravity and tides can be predicted using mathematical models and scientific observations. However, tides are more complex and can be affected by factors such as weather and ocean floor topography, making their prediction more challenging.
