What do you understand by free fall derive an expression for the acceleration due to gravity write the factors on which acceleration due to gravity depends?

1 Answer. (a) When an object moves towards earth vertically under the effect of gravitational force only, its motion is said to be free fall. On putting values of mE and RE, the value of g at the surface of earth obtained is g = 9.8 m/sec.

What do you understand by free fall derive an expression for the acceleration due to gravity write the factors on which acceleration due to gravity * Depends?

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.

What do you understand by free fall mention the factors on which the acceleration due to gravity on earth depends?

Gravity is measured in terms of the acceleration or movement that it gives to freely falling objects. At Earth's surface, the value of the acceleration of gravity is about 9.8 m/s². Thus, for every second an object is in free fall, its speed increases by about 9.8 m/s².

What do you mean by free fall?

In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute.

What are the factors on which acceleration due to gravity depends?

The acceleration due to gravity depends upon the radius of the earth,mass of the earth and on a constant having unit Nm^2/kg^2.

Free Fall Physics Problems - Acceleration Due To Gravity

What is free fall class 9th?

Answer. When a body or object falls towards earth due to gravitational force of earth and without any other force acting on it. It is called free. fall. The acceleration produced during free fall due to earth's gravitational force is the acceleration of free fall.

On what factors acceleration due to gravity depends Class 9?

Explanation: 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.

What is a free fall class 11?

What is Free Fall? Freefall is defined as a situation when a body is moving only under the influence of the earth's gravity. Since external force is acting on the ball, the motion will be accelerated. This free-fall acceleration is also known as acceleration due to gravity.

What is meant by free fall and acceleration due to gravity?

The falling of a body from a height towards the earth under the gravitational force of earth, with no other external forces acting on it is called free fall. Acceleration with which a body would fall freely under the action of gravity in a vacuum is known as the acceleration due to gravity.

What do you mean by free fall write the value of g with unit class 9?

The value of g is 9.8 m/s². When an object falls on the ground under the action of earth's gravity,i ts velocity increases at rate of 9.8 m/ s². When a body is dropped freely, it falls with an acceleration of 9.8 m/ s².

What is the free fall acceleration at its surface in terms of the free fall acceleration G at the surface of the earth?

What is the free-fall acceleration at its surface, in terms of the free-fall acceleration g at the surface of the earth? (2/9)g.

What is free fall due to gravity?

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

What is the acceleration of free fall class 10?

8m/s2.

What is a acceleration of free fall for Class 11?

Acceleration of free fall is the acceleration produced when a body falls under the influence gravitational force of the earth alone. It is denoted by g and its value on the surface of the earth is 9.8 ms−2. Physics.

What is the expression for acceleration due to gravity?

Its value near the surface of the earth is 9.8 ms^-2. Therefore, the acceleration due to gravity (g) is given by = GM/r².

On what factors does the acceleration due to gravity depends give the relation between g and g?

Although there exists a formula to express the relation between g and G in physics, there is no correlation between acceleration due to gravity and universal gravitation constant, as the value of G is constant. The value of G is constant at any point in this universe, and G and g are not dependent on each other.

How does acceleration due to gravity depends on the mass of planet class 9?

Given an object of mass m in a gravitational field due to a body of mass M, the force upon either would be GMm/(r^2) where G is the Gravitational constant, and r is the distance between the two masses. So the acceleration of a given mass due to gravity does not depend upon the said mass.

What is free fall Brainly?

Brainly User. Freefall is defined as a situation when a body is moving only under the influence of the earth's gravity. Since external force is acting on the ball, the motion will be accelerated. This free-fall acceleration is also known as acceleration due to gravity.

What is the acceleration of free fall Byjus?

Acceleration does not increase in a free fall. The acceleration on the surface of the earth is approximately equal to 9.8 m/s².

What factors affect free fall acceleration?

The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.

How do you find the acceleration of a free fall surface?

The free-fall acceleration near Earth's surface is a = -g = -9.8 m/s², and the magnitude of the acceleration is g = 9.8 m/s².

What is the free fall acceleration at the surface of a the moon and B Jupiter?

ali ergin. Apr 11, 2017. gmoon=1.62 ms2. gJupiter=24.79 ms2.

What is free fall acceleration due to gravity escape velocity centripetal force?

Expert-verified answer

The terms free fall, acceleration due to gravity, escape velocity and the centripetal force are all related to the term gravity.

What is the acceleration of free fall 9 Chapter 10?

Acceleration of free fall is 9.8 m s⁻², which is constant for all objects (irrespective of their masses).

What is the acceleration of gravity Class 9?

The value of acceleration due to gravity is g= 9.8 m/s².
