Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. … This means that for a given gravitational field strength,
the greater the mass of the object, the greater its weight
. Weight is a non-contact force because gravity exerts its force through a field.
What happens to the force of gravity if your weight increases?
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the
force of gravity decreases
.
Is the force of gravity affected by mass?
Gravitational forces are considered to be inherently linked to what we call ‘mass’. There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is
proportional to the masses of the objects
and weakens as the distance between them increases.
Does more weight mean more gravitational force?
Mass is the measure of an object’s matter (what it’s made up of).
The greater an object’s mass, the greater its gravitational force
. … The stronger the pull of gravity on an object, the greater its weight. In physics, weight is measured in newtons (N), the common unit for measuring force.
How does gravity affect an object’s weight?
Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. … This means that for a given
gravitational field strength, the greater the mass of the object, the greater its weight
. Weight is a non-contact force because gravity exerts its force through a field.
Is gravity stronger the higher you go?
Essentially, gravity holds our world together. … In addition, gravity is weaker at the equator because of centrifugal forces produced by the planet’s rotation. Gravity is also a
bit weaker at higher altitudes
, being farther from Earth’s center, such as the summit of Mount Everest.
Why gravity is not force?
In general relativity, gravity is
not a force between masses
. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line. … This explains why all objects fall at the same rate.
Is force equal to weight?
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity,
w = mg
. Since the weight is a force, its SI unit is the newton.
What happens when there is no gravity?
With less gravity, it is harder to keep your body strong. If the Earth’s gravity is lost,
all items held to the Earth’s surface by gravity would float away
. That includes the atmosphere, water, people, cars and animals. If an object were secured strongly to the Earth, it would probably remain attached.
Why is gravity the strongest force?
Actually, gravity is the weakest of the four fundamental forces
How is gravity calculated?
In SI units, G has the value 6.67 × 10
– 11
Newtons kg
– 2
m

. The direction of the force is in a straight line between the two bodies and is attractive. … The
acceleration g=F/m
1
due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s
– 2
.
What makes a gravitational force noticeable?
Unless someone is taking very precise measurements in a lab (see for example Cavendish’s famous experiment which determined the gravitational constant, G), the force of gravity must include
only really big objects (like the sun, the moon or a planet)
to be noticeable.
Does distance affect gravity?
Since
gravitational force is inversely proportional to the square of the separation distance
between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Where is gravity weakest on earth?
Mount Nevado Huascarán in Peru
has the lowest gravitational acceleration, at 9.7639 m/s

, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s

Where is there no gravity on Earth?
The Mystery Spot in California
is one of the many gravitational anomalies that you will find around the world. Discovered in 1939, this spot was opened to the public in 1940. Within the mystery area, you will be amazed to witness that the laws of gravity actually don’t seem to work.
Where is gravity strongest?
- The centrifugal force cancels out the gravity minimally, more so at the equator than at the poles.
- The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
