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.
What is the downward force on water?
The downward force on water is due to gravity, which pulls the water downward towards the Earth's center. This force is known as the weight of the water and is determined by the mass of the water and the acceleration due to gravity.
When a ball is thrown upwards is there any change in its acceleration all throughout its motion?
Yes, the acceleration of the ball will change. Initially, the acceleration is downward (due to gravity) while the ball is speeding up. As it reaches its peak height, the acceleration becomes zero. On the way back down, the acceleration is again downward and the ball speeds up due to gravity.
When a skydiver jumps out of a hovering helicopter so there is forward velocity. what is the skydiver's acceleration?
Initially, the skydiver will experience an acceleration due to gravity, which is approximately 9.81 m/s^2 downward. As the skydiver falls, air resistance will oppose this acceleration, causing the skydiver to reach a terminal velocity where the downward acceleration due to gravity is balanced by the upward force of air resistance.
A ball tossed vertically upward rises reaches its highest point and then falls back to its starting point during this time the acceleration is always?
The acceleration is always directed downward due to gravity. At the highest point, the acceleration is still acting downward, but its magnitude is zero as the ball momentarily stops before descending back down.

Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Yes, the acceleration due to gravity always points vertically downward, regardless of the direction of an object's velocity. This is because gravity is a force that attracts objects towards the center of the Earth.

What direction does weight always act in?
Weight always acts in the downward direction due to gravity.
An object is dropped and falls to the ground with acceleration of g if its thrown upward at an angle its acceleration would be 0 larger than g g upward g downward or none of the above?
The acceleration of the object would still be g downward, regardless of the angle at which it is thrown upward. The acceleration due to gravity always acts in the downward direction towards the center of the Earth. The only difference would be the horizontal component of the velocity due to the initial angle of the throw.
What is the direction of acceleration due to gravity in upward motion and downward motion?
In upward motion, the acceleration due to gravity acts downward, opposing the motion and causing the object to slow down. In downward motion, the acceleration due to gravity acts downward as well, aiding the motion and causing the object to speed up.
Is it possible for one to say that an object moving vertically downward can accelerate less than the value of acceleration due to Gravity?
No, an object moving vertically downward will always accelerate at the same rate as the acceleration due to gravity (9.81 m/s^2). This is because gravity is the force causing the acceleration of the object in free fall.
What happens to your weight if acceleration due to gravity somehow doubled?
If acceleration due to gravity doubled, your weight on Earth would also double. This means that the force of gravity pulling you downward would be twice as strong as it is currently, causing you to feel heavier.
Is it possible for one to say that an object moving vertically downward can accelerate less than the value of gravity?
No, an object moving vertically downward cannot accelerate less than the value of gravity if there are no other forces acting on it. The acceleration of an object in free fall near the Earth's surface is always equal to the acceleration due to gravity, which is approximately 9.8 m/s^2.
