If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?

Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.

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.
What is the direction of average acceleration?
The direction of average acceleration is downwards, in the direction of gravity. This is because gravity affects all objects, even objects that are moving in other directions.
What direction does the force of gravity apply to the rollercoaster car?
From what I know, Force of Gravity always acts in the vertically downward direction.
Can a direction of velocity of an object reverse at constant acceleration?
Sure. A pendulum and a park swing both have constant acceleration due to gravity, and the direction of their velocity changes over and over again until they're stopped.
What force that can change when acceleration due to gravity changes?
I suppose you are asking about what forces change when acceleration due to gravity changes. In this case, the formula for forces concerning acceleration due to gravity is as such: fg=mg. When acceleration due to gravity(g) changes, it affects the force of gravity which is also known as the weight of the object. This is shown as fg.
Is there acceleration in the y direction?
Yes , there is a constant acceleration is the y- axis. and that acceleration is called acceleration due to gravity or Gravity. Gravity attracts every falling body which is on y axis. that's why the gravity is on y axis which is constant
How do you calculate magnitude and direction of a object or truck?
-- First of all, you calculate the magnitude and direction of vectors. An object or a truck are not vectors. Things like their weight, velocity, and acceleration are. -- There are different methods and formulas for calculating each different vector. For example: . . . The truck's weight is (the truck's mass) x (the acceleration of gravity) downward . . . The truck's acceleration is (the rate at which its speed changes) in the direction in which its speed changes.
What does vertically upwards mean?
Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.
Where is the direction of acceleration due to gravity?
It's toward the center of the Earth. We call that direction "down".
What is a force that can change when acceleration due to gravity changes?
Weight
Why do you calculate center of gravity?
If a force acts in a direction which passes through the centre of gravity of the object then it will impart no rotational acceleration; only linear acceleration.
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.
