1 Answer.
The gravity acceleration
is in the same direction as the force of gravity, and thus toward the center of the earth accurately describes the force of gravity.
Which of the following best describes the force of gravity?
An
attraction between two objects that have mass
. An attraction between two objects due to their electrons. The force that keeps atoms and molecules bound together. The force that keeps objects from moving when they are at rest.
What is gravitational force described by?
Newton’s Law of Universal Gravitation
is used to explain gravitational force. … The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses’. Gravitational force surrounds us.
What is the force of gravity short answer?
The answer is
gravity
: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.
What is the force value of gravity?
Its value is
9.8 m/s
2
on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s
2
. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth’s surface.
How do you explain gravity?
Gravity is a force which
tries to pull two objects toward each other
. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall.
How gravity affects our daily lives?
Gravity is
very important
to our everyday lives. Without Earth’s gravity we would fly right off it. … Life on Earth needs the Sun’s light and warmth to survive. Gravity helps the Earth to stay just the right distance from the Sun, so it’s not too hot or too cold.
What is gravitational force and example?
Gravitational force is the force of attraction on a body by earth. Example –
Leaves and fruits fall from a tree downwards towards the ground due to
the gravitational pull.
Can gravity be proven?
Most everyone in the scientific community believe gravitational waves exist, but
no one has ever proved it
. That’s because the signals from gravitational waves are usually incredibly weak.
Who invented gravity?
Physically,
Sir Isaac Newton
was not a large man. However, he had a large intellect, as shown by his discoveries on gravity, light, motion, mathematics, and more. Legend has it that Isaac Newton came up with gravitational theory in 1665, or 1666, after watching an apple fall.
Is gravity a real force?
gravity, also called gravitation, in mechanics, the
universal force of attraction acting between all matter
. … On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
How gravity is created?
Earth’s gravity comes from all its mass
. All its mass makes a combined gravitational pull on all the mass in your body. … You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet.
Where is gravity the strongest?
Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s
2
, while the highest is at
the surface of the Arctic Ocean
, at 9.8337 m/s
2
.
How do you calculate the value of gravity?
| Location Distance from Earth’s Center(m) Value of g (m/s 2 ) | 50000 km above surface 5.64 x 10 7 m 0.13 |
|---|
What is the force of gravity on each planet?
| Space object g, gravitational field strength (N/kg) | Venus 8.8 | Earth 9.8 | Moon (satellite) 1.7 | Mars 3.7 |
|---|
