Forces act on matter, and can accelerate that matter. Gravity is one of the four fundamental forces (along with the strong interaction or strong force, the weak interaction or weak force, and the electromagnetic force). Gravity creates a curvature in spacetime, and things can "slide" or "fall" down into this curvature. Gravity, which is a fundamental characteristic of all matter, attracts matter and accelerates it if it can. We often refer to the earth sitting in the bottom of a gravity wellout of which we must climb to get into space. We have gravity accelerating us, and the chemical engines of rockets forcing us (or our payloads) up agains that pull of gravity.

What kind of force is gravitational force?
Gravitational force is a form of potential energy
Why does a feather fall at the same rate as a ball when both are dropped from the same height and vacuum?
The feather and the ball both experience a gravitational force towards the centre of the earth which scales in proportion to their mass (the force is greater on the ball than on the feather).The force manifests itself as an acceleration which scales in inverse proportion to the mass (the same force would make the feather accelerate faster than the ball).So the proportionalities cancel:in tabular form-relative mass for same force for same gravitating bodyFeather : low : easy acceleration : low coupling to gravityBall : high : sluggish acceleration : higher coupling to gravityin algebraic form -acceleration = force/mass = (const. x mass) / massif the acceleration is the same, so will the kinematics and they will "fall at the same rate".Note that there are actually two kinds of mass in this - inertial (that resists acceleration) and gravitational (that couples to a gravitational field). The fact that these are the same is "deep" and leads to Einstein's Genral Theory of Relativity.
The gravitational force with which the earth attracts an object?
The gravitational force with which the Earth attracts an object is known as the object's weight. Weight is directly proportional to an object's mass and the acceleration due to gravity (9.81 m/s^2 on Earth). This force pulls objects toward the center of the Earth.
What is gravity speed?
Gravity is not a form of speed but a force that attracts objects with mass towards each other. The speed at which an object falls towards the Earth due to gravity is approximately 9.8 meters per second squared, which is known as acceleration due to gravity.
What is the acceleration produced by some force pushing or pulling on something?
Remember Newton's Second Law of Universal Dynamics. Put into algebraic form it is F = ma To answer your question a = F/m Acceleration is equal to force(F) divided by mass(m) of the object being pushed/[pulled.
What is the weakest form of force?
Gravitational force
Is fmg the formula that tells the gravitational attraction between m and the earth?
Yes, the equation is Fg = mg. This means that the force of gravity is equal to the mass times the gravitational acceleration (which is 9.8 m/s2). For example, the force of gravity on a 2 kg object would be 2*9.8, which is 19.6 Newtons. (This comes form the equitation F = ma, substituting g, the gravitational acceleration, for a).

Which is not caused by gravitational force?
Two atoms come together to form a molecule.

How are Force Acceleration and Mass related?
(Force on an object) = (the object's mass) times (its acceleration)

Is measured using a spring scale mass or weight?
Weight. Actually, a spring balance measures the downward force form a mass under the local gravitational acceleration, e.g. any mass would weigh less on the moon (about one sixth of that on earth.)
Is weight Weight is measured by using a spring scale?

Why does the moon not get pulled towards the earth?
Allthough moon is pulled by earths gravitational field but due to another forces like centrifugal force of moon which is developed by moon while revolving around earth keep it away form collpsing with earth. Also there are many other bodies in space which neutralize the gravitational pull of earth to moon.
How does Newtons second law relate to speedometers?
Newton's second law states that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. In the context of a speedometer, this means that the force applied to the vehicle's wheels by the engine will determine the acceleration, which in turn affects the speed displayed on the speedometer. More force results in greater acceleration and faster speeds displayed on the speedometer.
