When a falling object has reached its teminal velocity its accleration?
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
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.
What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
What keeps a falling object from accelerating?
Air resistance and buoyant force are two factors that can oppose the acceleration of a falling object. These forces act in the opposite direction to the force of gravity, thus slowing down the object's acceleration.
When the upward and downward forces on a falling object are equal the object reaches?
When the upward and downward forces on a falling object are equal, the object reaches terminal velocity. At terminal velocity, the object stops accelerating and falls at a constant speed.
Can an object have velocity and acceleration vectors that point in opposite directions?
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
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.
The acceleration of a falling object is cause by the force of?
Gravity
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
What is the acceleration of a falling object caused by?
Newton's Second Law of Acceleration says it is gravity.
How does the acceleration of gravity vary as one goes upward from the surface of the earth?
The farther away from an object on gets, the less powerful the gravitational pull by that object is. As one moves upward from the surface of the earth, the earth's gravitational pull has less of an effect. Since acceleration due to gravity is negative (-9.8 m/s2), the acceleration due to gravity will increase (the acceleration would decrease if you are considering falling down towards the earth to be positive, not negative velocity). This means that the object will not fall as fast, or that of the object is traveling upwards, it will not slow down as rapidly.
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.
