Without air in the picture, gravity causes all falling objects to accelerate at the same rate,
and grow their speed by the same amount after the same amount of time, regardless of
their size, mass, or weight.
We never see this in daily life, because anything we see falling is falling through air. The
effect of air resistance on a falling object depends on the object's weight, size, shape, and
speed, so its behavior in response to gravity alone is obscured.
What else can I help you with?
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
The speed at which an object falls and the acceleration at which it falls are always the same value?
The speed at which an object falls and the acceleration at which it falls are not the same value. The acceleration due to gravity is constant at about 9.8 m/s^2 near the surface of the Earth, but the speed of an object can change as it falls depending on factors such as air resistance.
Is it true that the acceleration of an object is constant?
No, the acceleration of an object is not always constant. An object can have a variable or changing acceleration depending on the forces acting upon it. For example, an object in free fall has a constant acceleration due to gravity, while an object experiencing friction will have a changing acceleration.
How much does the speed of an object in free fall change each second?
In free fall, the speed of an object increases by 9.8 meters per second every second, due to the acceleration of gravity. This acceleration is constant near the surface of the Earth, making the speed increase steadily.
Why do objects accelerate as they fall to the ground?
Objects accelerate as they fall to the ground due to the force of gravity acting on them. As the object falls, the force of gravity causes it to increase in speed, resulting in acceleration. This acceleration is a result of the unbalanced force acting on the object.
What is the formula for computing speed in relation to the weight?
In general the velocity (speed) of an object undergoing constant acceleration, a, is V=vo+at where vo= initial velocity and t= duration of acceleration. For an object in free fall in a vacuum, a=g=9.8m/s2.
How does speed and acceleration effect gravity?
Speed and acceleration do not directly affect gravity. Gravity is a fundamental force that acts on all objects regardless of their speed or acceleration. However, an object's speed and acceleration can influence its motion within a gravitational field, such as causing it to orbit a larger body or fall towards it at an accelerated rate.
What most determines how fast an object will fall on earth?
The acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth, is the primary factor that determines how fast an object will fall. Objects will fall faster if they have a higher acceleration due to gravity and slower if they have a lower acceleration due to gravity. Other factors like air resistance and the density of the object can also have a small effect on the speed of fall.
How do I find the free-fall acceleration only knowing the variables of distance and initial speed?
To find free-fall acceleration using only distance and initial speed, you can use the kinematic equation: distance = (1/2) * acceleration * time^2. Since the initial speed affects the time of fall, you would need to know the time of fall or other variables in order to solve for acceleration with just distance and initial speed.
Is it possible that the velocity of an object be in a direction other than the direction of accalaration?
Of course. When you toss a ball or a stone UP into the air, thenfor all the time until it reaches its peak and begins to fall, its velocityis upward but its acceleration is downward.The acceleration of gravity is always downward, but material objectsfrequently have upward velocities.In any situation where an object's acceleration is opposite to its velocity,a Physicist would say that the object is "slowing down".Another example is motion at a steady speed in a circle. In that case, theacceleration and velocity are always perpendicular. The acceleration actsonly to change the direction of the object's motion, but not its speed.
Why do falling objects speed up as they fall?
Falling objects speed up due to the acceleration of gravity. As an object falls, the force of gravity causes it to accelerate towards the Earth at a rate of 9.8 m/s^2. This acceleration increases the object's speed over time.
What happens to the speed of an object that is falling in free fall?
It increases at the rate of acceleration due to gravity, 9.8m/s2, until air resistance and the weight of the object become equal but opposite in direction. At that point there is no further acceleration and the object has reached its maximum velocity, called terminal velocity.
