It is denoted as g. Now for different planets the value of acceleration due to gravity is different. So, for a body to have no weight, the acceleration due gravity must be zero. Hence,
it is possible that a body can have mass but no weight
.
Can a body have mass but no weight give reason Class 9?
Yes, a body can have mass but no weight at the centre of the earth. This is because
acceleration due to gravity (g) decreases as we go deep into the earth and becomes zero at the
centre.
Can a body have a zero mass and zero weight?
It is not possible for a body to have zero mass
( no body can exist without mass ) but a body can have zero weight….. … At the center of the earth the gravitational acceleration is 0 so multiply 0 with mass and any no. multiplied with 0 is 0 so weight can be 0.
Can a body have zero mass explain?
A physical body cannot have zero mass
. … Since the weight of a body depends on the gravitational field, a body with the same mass can have different weights at different places. The weight of a massive object can even be zero.
Is it possible for a body to have inertia with no weight?
yes
, a body can have intertia (i.e., mass) but not weight. In a fact a body always has mass (i.e., intertial) but the gravitational force on it can zero.
Where is the true weight of the body zero?
The true weight of a body will be zero
where the gravitational effects are nil
e.g. at the centre of Earth or deep in space far away from the given star or planet.
Can a body have 0 weight?
In the International Space Station,
the weight of any object is zero
. When a body is in free fall, the weight is zero as the body is falling with the same acceleration as the acceleration due to gravity. Note: When the acceleration due to gravity decreases, the weight of the body also decreases.
Why a body have mass but no weight?
Yes, a body can have mass but no weight at the centre of the earth. This is because
acceleration due to gravity (g) decreases as we go deep into the earth and becomes zero at the centre
.
Does matter have mass?
In classical physics and general chemistry, matter is
any substance that has mass
and takes up space by having volume.
In which condition can a body with fixed mass have zero weight?
Weightlessness
is the condition in which the weight of the body seems to be zero. A body with a fixed mass will be weightless under the following conditions: When a body falls freely under the influence of the force of gravity only. When the acceleration of a falling body is equal to the acceleration due to gravity.
Is it possible for a body to have inertia but no weight class 11?
yes,
a body can have intertia
(i.e., mass) but not weight. In a fact a body always has mass (i.e., intertial) but the gravitational force on it can zero.
Is it possible for a body to have acceleration without velocity?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously.
Why is the weight of a freely falling body zero?
Every body on
this earth is attracted by the gravitational pull of the earth
. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object. …
What is true weight of a body?
“The weight W of
a body is equal to the magnitude F
g
of the gravitational force on the body
.” The gravitational acceleration varies from place to place. Sometimes, it is simply taken to have a standard value of 9.80665 m/s
2
, which gives the standard weight.
Can weight be negative physics?
Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force). Since
weight acts in the downward direction it will be negative
.
What is the weight of the body during free fall?
The weight of the body during a free fall is
same as the normal rate of the body
because in both the cases the force acting on the body is downward gravitational force or u can say mg.
