When dealing with the force of gravity between two objects, there are only two things that are important –
mass, and distance
. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
What two factors affect gravity quizlet?
The strength of the force of gravity between two objects depends on two factors:
the mass of the objects and the distance between them
.
What are the factors affecting gravity?
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors,
mass and distance
, affect the strength of gravitational force on an object.
What increases gravitational force?
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as
the mass of either object increases
, the force of gravitational attraction between them also increases.
What objects does gravity cause?
When objects fall to the ground, gravity causes them
to accelerate
. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.
What are the two factors involved in determining force?
The two factors are
the mass of the objects and the coefficient of friction between them
. The angle between them is also very significant.
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 does the force of gravity do to objects quizlet?
Gravity is a force of attraction between objects that is due to their masses. The force of gravity can
change the motion of an object by changing its speed, direction, or both
.
Does gravity increase with height?
gravity increases with height
. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) … gravity is a large force. there is no gravity in a spacecraft orbiting the Earth.
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.
At what height does the gravitational force end?
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of
one half of the Earth’s radius
– (9.8 m. s
− 2
per 3,200 km.)
Where is gravity strongest on earth?
In the case of the earth, the force of gravity is greatest
on its surface
and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth). Of course, the earth is not a uniform sphere so the gravitational field around it is not uniform.
Is gravity the key to everything?
In science, knowing what you don’t know is a good start. In this case, it has led scientists to believe that
finding a quantum solution to gravity is a key
— perhaps the key — to understanding the universe on the most fundamental level. … Gravity is not the force of attraction that makes things fall straight down.
How do you teach gravity?
Put a globe in the center of the floor
and tell students that gravity is pulling them towards it really really hard. One group at a time, ask them to form themselves around the globe so that they are as close to it as possible. Explain that Earth’s gravity is incredibly strong and pulls objects towards its center.
What two qualities of objects does gravity depend on?
We also know that gravity depends on
the mass of the object doing the pulling
(in our case, the Earth), the mass of the object being pulled (such as a person), and the distance between the two.
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.
