There is no height at which gravity completely ceases to exist. Gravity diminishes with distance from a massive body, such as the Earth, but it never reaches zero. Even at great heights, such as in space, gravitational effects are still present, although they may be weaker. For example, the International Space Station orbits Earth at about 400 kilometers where gravity is still about 90% of what it is at the surface.

What is the acceleration of gravity at a height of 6400 km above the Earth's surface?
At a height of 6400 km above the Earth's surface, the acceleration due to gravity can be calculated using the formula ( g' = g_0 \left( \frac{R}{R + h} \right)^2 ), where ( g_0 ) is the acceleration of gravity at the Earth's surface (approximately 9.81 m/s²), ( R ) is the Earth's radius (about 6400 km), and ( h ) is the height above the surface. Substituting the values, the effective gravity at this height is approximately 2.45 m/s². This demonstrates that gravity decreases with altitude, being significantly weaker at that height compared to the surface.
If a safe height to jump from is 2 meters on Earth what is the safe height on the moon?
On Earth's moon, it would be around 10 metres (the moon has only one sixth the gravity, but no air to create resistance).
What does gravity do to objects that are thrown up?
Gravity acts as a downward force on objects that are thrown upwards, causing them to decelerate until they reach their peak height. At this point, their velocity becomes zero before gravity pulls them back down. As they descend, gravity accelerates them downwards, leading to an increase in their speed until they reach the ground. Ultimately, gravity ensures that all thrown objects return to the Earth's surface.
Why you jump on the moon?
Humans were able to jump higher on the moon due to its lower gravity compared to Earth. The moon's gravity is about one-sixth that of Earth, allowing for greater mobility and height in jumps.
How does gravity effect a firework on its way up?
Gravity acts as a force that pulls the firework downward throughout its ascent. As the firework is launched, it initially overcomes gravity due to the thrust generated by the propellant. However, as it rises, gravity gradually slows its ascent until it reaches its peak height, where the upward momentum is completely countered by gravitational force. After reaching this apex, gravity then causes the firework to fall back down, leading to its eventual explosion at the peak.
When you throw a substance in air at what height there in no gravity at what height there is least gravity and at what height there is normal gravity?
The farther it is from Earth, the less gravity will there be. Gravity will never completely disappear.
How does gravity affect a person's height or stature?
Does gravity affect a person's height and why?
does gravity increases or decreases with height?
It decreases with height.
How do I work out a vertical height when it gives me kg and kJ of Ep and Gravity?
Ep (joules) = mass * acceleration due to gravity * height So: height = Ep / (mass * acceleration due to gravity)
How does gravity work in the height?
as we go up gravity decreases
Would zero gravity be at the same height and positive gravity be pulling and negative gravity be pushing?
No
What effects an wave height?
Gravity
What causes an object to fall from a height?
Gravity causes an object to fall from a height. Without gravity, the object would just be floating in the air.
What does gravitational potential energy depend on of the object?
Mass, Height, and Gravity Gravitational Potential Energy= Mass * gravity * height
When does gravity affect the height of an ollie?
always
Can acceleration due to gravity vary with respect to height?
No, acceleration due to gravity is a constant at 9.81ms-2. It cannot be influenced by other factors such as height.
How can the potential energy be calculated for an object at a certain height?
The potential energy of an object at a certain height can be calculated using the formula: potential energy mass x gravity x height. This formula takes into account the mass of the object, the acceleration due to gravity, and the height at which the object is located. By plugging in the values for mass, gravity, and height, you can determine the potential energy of the object.
