Question

define free fall , gravity acceleration, mass ,weight​

Answer 1

$\Huge{\boxed{\pink{\mathbb{ANSWER}}}}$

$\Large{\bold{What\:is\:free\:fall?}}$

If an object is falling from a particular height on which only gravitation force is acting, with no other forces, then the object is said to be in free fall.

$\Large{\bold{What\:is\:gravitational\:acceleration?}}$

Gravitational acceleration is the acceleration which acts on an object which is caused by only gravitational force.

$\Large{\bold{What\:is\:mass?}}$

Mass is the content present inside a matter. Mass is constant. It is same everywhere.

$\Large{\bold{What\:is\:weight?}}$

Weight is a force which is exerted on a body by gravity. Weight is not same. As the acceleration due to gravity changes with respect to the radius of Earth, so, the weight differs from place to place.

Weight = mg

Where, 'm' is the mass of the object and 'g' is the acceleration due to gravity.

$\huge\mathfrak{Answer:}$

$\large\red{Free\:fall:}$

The falling of a body (or object) from a height towards the earth under the gravitational force of earth (with no other forces acting on it) is called free fall.

$\large\red{Acceleration\:due\:to\:gravity:}$

The uniform acceleration produced in a freely falling body due to the gravitational force of the earth is known as acceleration due to gravity.

$\large\red{Mass:}$

The mass of a body is the quantity of matter (or material) contained in it.

$\large\red{Weight:}$

The weight of a body is the force with which it is attracted towards the centre of the earth.
