Why does acceleration due to gravity always point vertical downward?
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
How is acceleration due to gravity be zero in a parachute?
At terminal velocity (constant velocity), the acceleration is zero, but prior to that, there is a downward acceleration.
The downward force exerted by an object?
The downward force exerted on an object is caused by gravity (from the Earth). This force is called weight and can be calculated by multiplying the mass of the object by the acceleration due to gravity on Earth (about 9.8).
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
What is equivalent of acceleration due to gravity?
acceleration due to gravity of earth is 9.8ms-2

Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Acceleration only depends on the direction of the applied force and is independent of the velocity of the object, so gravity is always pointing down.

Why is the mass of an object same on the moon as it is on earth but the weight is different?
Mass is the amount of matter in an object. It does not change based on gravity. Weight is the force an object exerts 'downward' due to gravitational acceleration. Force = (mass)*(acceleration). Acceleration due to gravity is less on the Moon than on Earth.

When is acceleration due to gravity positive and when is it negative?
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
What is gravity greater then?
The acceleration due to gravity is 9.81 meters per second. Since Force = Mass x Acceleration, the force of gravity would be the mass times 9.81.
What is accileration due to gravity on earth?
Acceleration due to gravityThe acceleration produced in the motion of a body under gravity is called Acceleration.
Is the acceleration of an object proportional to its weight?
If you meant to say mass instead of weight, the acceleration of an object is inversely proportional to mass, because F=ma. However for falling objects where acceleration is equal to gravity, the weight is not a variable.
What is the acceleration for the pull of gravity?
If you mean acceleration due to gravity it is ~9.8m/s2
