How does gravity hold things down?
We don't actually know. As far as we can tell, it boils down to "because that's how things are." Most theories of gravity at most push that back one step: "Because mass curves spacetime" "Why?" "Because that's how things are."
What does weaker than a nuns piss mean?
The phrase "weaker than a nun's piss" is a colloquial expression used to emphasize something as extremely weak or lacking in strength. It is a humorous way to exaggerate the level of weakness.
Is there a difference between gravity and inertia?
Yes, gravity is the force of attraction that exists between all objects with mass, pulling them toward each other. Inertia, on the other hand, is the resistance of an object to changes in its state of motion. Gravity is a force that acts on objects, while inertia is a property of objects themselves.
Why the acceleration due to gravity depends on where on the earth you are?
The acceleration due to gravity varies depending on your location on Earth because gravity is stronger closer to the center of the Earth due to the mass underneath you. This means that at different latitudes and elevations the gravitational force experienced by an object will be different.
What is the measure of the force of gravity in newtons?
The measure of the force of gravity on an object is approximately 9.81 newtons per kilogram. This value is commonly rounded to 10 newtons per kilogram for simplicity in calculations.
Does gravity cause a rock to roll down a hill?
Yes, gravity is the force that pulls the rock downhill, causing it to roll. The steeper the slope of the hill, the greater the gravitational force acting on the rock, which accelerates its movement.
When you are rounding a curve what force comes into play?
When rounding a curve, the centripetal force comes into play. This force is directed towards the center of the curve and is necessary to keep an object moving in a curved path rather than continuing in a straight line.
What are the similarities of mass and gravity?
Both mass and gravity are fundamental properties of matter. Mass is the measure of the amount of matter in an object, while gravity is the force that attracts objects with mass towards each other. The greater the mass of an object, the stronger its gravitational pull.
If the tree is 100 feet tall, then the acceleration of gravity, and therefore the weight
of apples, is about 0.0005 percent less at the top than it is halfway up.
================================
Using:
Earth radius = 4,000 miles
Tree height = 0.02 mile
Halfway = 0.01 mile
(4000.02 / 4000.01)2 = 1.000005
What happens if water hits terminal velocity?
If water were to reach terminal velocity, it would fall at a constant speed due to the balance between gravity pulling it down and air resistance pushing it up. This means that the water would no longer accelerate and would continue to fall at that maximum speed until it reaches the ground or another surface.
We have no reason to think that the force of gravity has or ever will become weaker over time.
An example of overcoming gravity?
-- holding an apple in your hand
-- walking up stairs
-- driving up a hill
-- washing the 2nd-floor windows with a garden hose
-- hanging up your coat
-- placing an artificial satellite in low-earth-orbit
-- picking up one bowling ball that's standing next to another one
Which of these terms can be defined as a root's downward groth as a response to gravity?
Geotropism is the term used to describe a root's downward growth in response to gravity. It is a plant's natural ability to orient itself based on the pull of gravity, allowing roots to grow in the optimal direction for water and nutrient absorption.
Do heavy objects accelerates more than light ones?
In the absence of air resistance or other external forces, heavy objects and light objects will accelerate at the same rate due to gravity. This is known as the equivalence principle and was famously demonstrated by Galileo through his experiment with dropping different objects of various weights from the Leaning Tower of Pisa.
Why is gravity important to a normal pen?
simply, a pen writes as the ink flows down through its nib. the force of gravity is the only thing (in general circumstances) that pulls the ink out. i.e. no gravity, no flow of ink and no writing!
What is the importance of acceleration due to gravity?
Force = Mass x Acceleration
F = ma
W=mg
It is the intensity of the gravitational field. The acceleration. due to gravity is the force experienced by a body of unit mass in a gravitational field.
it is the force experienced by a body of unit mass towards the centre of the earth by the pull of the earth.
What is the accelaration gravity of the center of Earth Surface?
At the earth's center, the acceleration/force of gravity is theoretically zero.
(At least the force of gravity between the earth and an object at its center. There's still the gravitational forces
between the object and everything else ... the sun, moon, stars, etc.)
What is earth gravity in decimals?
There is no fixed figure for earths gravity.
The effect of earths mass (or gravity) depends on its mass and how close you are to it.
the gravitational force (f) on an object (by the earths gravity) can be calculated by:
.
f (newtons) = (G * m1 * m2) / d^2
.
key:
m1 = earths mass (5.974 * 10^24 kg)
m2 = objects mass (kg)
d = distance between their centres of gravity (metres)
G = newtons gravitational constant (6.672 * 10^-11)
.
notes:
the force on the object is equal to the reaction force on the earth.
Why do heavier objects fall more slowly than lighter objects?
They don't. The basic physics behind the situation says that all objects fall together, regardless of their mass, weight, race, color, creed, national origin, or political affiliation.
In the reral world, especially on Earth, we occasionally see things falling at different rates.
How can you create zero gravity?
There is no place in the universe that has zero gravity. No matter where you are some type of gravitational force is acting upon you. So there is no way to create zero gravity even in the vastness of space.
What is a abbreviation for the laws of gravity?
The abbreviation for the laws of gravity is generally referred to as Newton's laws of motion.
What does gravity have to do with parachutes?
Gravity is the force that pulls a parachute and its user towards the ground. When a parachute is deployed, it increases air resistance, which counters the force of gravity and slows down the descent of the user. The balance between gravity and air resistance allows the parachute to lower the user safely to the ground.
How the force of gravity affects you every day of your life?
It's responsible for keeping my feet on the ground, my gluteous maximus gluted to
my chair, my keyboard and my papers on the desk, my desk on the floor, my food
on the plate, and ... an item we don't usually notice ... a sea of air all around me,
for my convenience and survival.
When the volume is constant how do the masses of 2 objects differ?
When the volume is constant, the masses of two objects will differ based on their densities. The object with a higher density will have a greater mass compared to an object with a lower density. Density is a measure of how much mass is packed into a given volume, so if the volume is constant, objects with higher density will have greater mass.
Why is gravitational force important to your universe?
As a big part, the gravitational force is what keeps us on the earth but other things make it necessary like the creation of elements in stars and light bending around objects like black holes and stars.
