How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
What is the acceleration by a freely falling object 5 seconds after it is dropped from rest?
It depends if it is affected by air resistance or not. If not then all objects close to the surface of the Earth have an acceleration of 9.81ms^-2 in free fall. If it is affected by air resistance you need all sorts of more information to answer that question, like the drag coefficient of the air.
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5
Two identical stones are dropped from a tall building one after the other Assume air resistance is negligible While both stones are falling what will happen to the vertical distance between them?
it will increase
The distance s meters traveled by a falling body starting from rest after time t seconds is?
If air resistance can be ignored, the distance in meters is 4.9t2. Note that 4.9 is half the numerical value of Earth's acceleration (9.8 meters per second square).
Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases the acceleration of a falling leaf from a tree. As the leaf falls, air resistance opposes its motion, slowing it down. This results in a lower acceleration compared to if the leaf were falling in a vacuum with no air resistance.
Does air resustance increase or decrease the acceleration of a falling abject?
Decrease.
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.
Does acceleration increase or decrease during free fall?
Acceleration remains constant during free fall at approximately 9.81 m/s^2, assuming no significant air resistance. This is due to the force of gravity acting on the falling object, resulting in a uniform acceleration towards the Earth.
How does air resistance affect the acceleration of a falling abject?
Air resistance creates friction and slows a falling object.
What is the acceleration of a falling abject?
The acceleration of a falling object near the Earth's surface is approximately 9.81 m/s^2, assuming air resistance is negligible. This acceleration is due to gravity and causes the object to increase its velocity by 9.81 m/s every second it falls.
Acceleration due to gravity on a falling object is what?
The acceleration due to gravity on a falling object is approximately 9.81 m/s^2, assuming no air resistance. This acceleration causes the object to increase its velocity by 9.81 m/s each second it falls.
How air resistance affect the acceleration of falling objects?
Air resistance causes friction and slows an object.
Why the air resistance decrease the acceleration on falling object?
Air resistance applies a force opposite to the direction of motion of a falling object. This force opposes the force of gravity, reducing the net force acting on the object, and hence reducing its acceleration. As the object's speed increases, the air resistance force also increases, further hindering its 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.
A falling stone has zero acceleration?
Only if it has enough wind resistance to cancel out gravity.
Does air resistance decrease as you move faster?
No, air resistance actually increases as you move faster. This is because the faster an object moves through the air, the more air particles it collides with per unit time, leading to a higher force of air resistance.
