Answer: The statement
is false
.
Is mass of an object variable write true or false?
The mass of an object is dependent upon the value of the acceleration of gravity. The standard metric unit of mass is the kilogram. Mass depends on how much stuff is present in an object. The mass of an object
is variable and dependent upon its location
.
Is gravity a contact force True or false?
A
non-contact force
is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force which acts on an object coming physically in contact with it.
Is it true or false that mass changes when gravitational force changes?
Gravity is a result of MASS. TRUE or FALSE: Gravity is a result of weight.
The object’s MASS does not change
.
Has mass and weight True or false?
In common usage, the mass of an object is often referred to
as its weight
, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.
What is difference between weight and mass?
Mass is a measure of how much force it will take to change that path. … Weight, on the other hand, is a measure of the amount of downwards force that
gravity
exerts on an object. This force increases with the object’s mass: the more inertia it has, the harder gravity pulls.
What’s a true or false question?
A true or false question consists of
a statement that requires a true or false response
. There are other variations of the True or False format as well, such as: “yes” or “no”, “correct” or “incorrect”, and “agree” or “disagree” which is often used in surveys.
What is the weight of 1 kg of mass?
On Earth, a 1 kg object weighs
9.8 N
, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.
Why do we say weight instead of mass?
So Why Do People Say Weight instead of Mass? People often use “weight” to mean “mass”, and vice versa, because
Gravity is almost the same everywhere on Earth
and we don’t notice a difference. But remember .. they do not mean the same thing, and they can have different measurements.
What is formula for mass?
Mass is always constant for a body. One way to calculate mass:
Mass = volume × density
. Weight is the measure of the gravitational force acting on a mass.
Why is gravity a non-contact force?
Gravitational force is a force of attraction between the earth and the objects on Earth. … Gravitational force is considered to be a non-contact force
because it is an attracting force which does not include contact between the objects to exert force
.
Which friction is the largest?
Static friction
is strongest, followed by sliding friction, and then rolling friction, which is weakest.
Is gravity a field force?
Gravity as a field of force
The Earth has a gravitational field that will attract any object with mass towards the centre of the planet.
Which is the strongest force in nature?
The strong nuclear force, also called the strong nuclear interaction
, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
What two factors affect the size of gravitational force?
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.
Does mass affect the force of gravity?
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.
