Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.

∙ 14y agoThe direction of acceleration is toward the center of the earth, even if the object started out with some horizontal velocity.

How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
Is acceleration always in the same direction as the unbalanced force?
No, acceleration is change in velocity. (And velocity is speed in a certain direction.) If an object slows down, then it is changing velocity and thus accelerating. (In this case, the acceleration is negative.) If an object changes direction, then it's velocity changes, so this is also acceleration. (This is centripetal acceleration.)
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
What affects the acceleration of an object?
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
What is the direction of the acceleration of an object that is slowing down while heading northward?
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
Is An object moving with a certain direction with an acceleration in the perpendicular direction?
There can be.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
Acceleration occurs when an object?
Changes direction.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
No. For you to know acceleration you need the rate of change of speed and the direction.
Is it possiblean object is moving in a certain direction with an acceleration in the perpendicular direction?
no
If the net force on an object is in negative direction what will the direction is the resulting acceleration be?
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
