what is the direction of acceleration due to gravity?
5618
The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.

If acceleration points in the same direction as the velocity, the object will be speeding up. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

If you travel with a constant acceleration, your velocity is always changing, but it's changing by a consistent amount each second. The acceleration due to gravity on the Earth has the constant value 9.8 m/s2, so you can imagine this like dropping something from a skyscraper.

The Direction of the Acceleration Vector. Since acceleration is a vector quantity, it has a direction associated with it. The direction of the acceleration vector depends on two things: whether the object is speeding up or slowing down. whether the object is moving in the + or - direction.

The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. ... The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2 (32.1740 ft/s2).

Fg = mg. Then a = g, where g is called the acceleration due to gravity. Near the surface of the earth its magnitude is g = 9.8 m/s2 and its direction is downward. Near the surface of the earth all objects experience the same acceleration due to gravity in the downward direction, regardless of their mass.

Weight = (mass) x (acceleration of gravity) On Earth, acceleration of gravity = 9.8 meters per second². Divide each side of the equation by (9.8 m/s²).

Now the ball is under the influence of gravity, which, on the surface of the Earth, causes all free-falling objects to undergo a vertical acceleration of –9.8 m/s2. This acceleration is negative because its direction is vertically downward.

g or G. An acceleration equal to the acceleration of gravity, 980.665 centimeter-second-squared, approximately 32.2 feet per second per second at sea level; used as a unit of stress measurement for bodies undergoing acceleration. See acceleration of gravity; gravity. acceleration of gravity (symbol g)

What are the daily life examples of acceleration against the direction of motion? 1. If one throws a ball straight up into the air the acceleration of the ball when it is moving upward is against the direction of the ball. The acceleration due to gravity is always pointing down.

noun. the acceleration of a body falling freely in a vacuum near the surface of the earth in the earth's gravitational field: the standard value is 9.806 65 metres per second per second or 32.174 feet per second per secondSymbol: g Also called: acceleration due to gravity, acceleration of gravity.

Originally Answered: Is gravity and acceleration the same thing? ... Gravity is a two-way interaction between energy and the curvature of spacetime. Acceleration is a property of an object that says how much its velocity changes, and it can be caused by many things, including gravity but not limited to it.

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. G and g are not dependent on each other.

Accelerations are caused by an unbalanced or net force. The net force is always in the same direction as the acceleration. For objects moving in circles at constant speed, the net force is directed towards the center of the circle about which the object moves.

In physics, gravitational acceleration is the free fall acceleration of an object in vacuum — without any drag. This is the steady gain in speed caused exclusively by the force of gravitational attraction. ... This equality is true regardless of the masses or compositions of the bodies.

It is also true that a free falling (no air resistance) object falls with an acceleration of 9.8 m/s2—but it's still just the gravitational field. It doesn't matter what object you put near the surface of the Earth, the gravitational field due to the Earth is constant and pointing towards the center of the Earth.

The acceleration of the object must be directly proportional to its displacement from some fixed point, and the acceleration must be directed to that fixed point. That is when the motion of the body will be simple harmonic.
