On earth, the vertical acceleration of any object that's free to move vertically,
and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,
directed downward. The source of the acceleration is the mutual gravitational
attraction between the object and the earth.
What else can I help you with?
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
What is the magnitude of the upward acceleration of the load of bricks?
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.

What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
What is the magnitude of the upward acceleration of the load of bricks?
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
If a moving object speeds upin what direction is the acceleration?
If a moving object is speeding up, the acceleration is in the same direction as the object's motion.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
Why is an object moving in a constant speed undergoing?
An object moving at a constant speed is not undergoing acceleration because acceleration is a change in velocity over time. Since the object's speed is not changing, there is no acceleration.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
What is the difference between tangential and centripetal acceleration?
Tangential acceleration is the change in speed of an object moving in a circular path, while centripetal acceleration is the acceleration that keeps an object moving in a circular path. Tangential acceleration affects the speed of the object, while centripetal acceleration affects the direction of the object's motion.
When an object is turning a corner what direction is the acceleration?
The acceleration of an object turning a corner is directed towards the center of the circle that the object is moving along. This acceleration is called centripetal acceleration and is responsible for changing the direction of the object's velocity, keeping it moving in a curved path.
