Why don't objects on Earth accelerate at 9.8 meters per second per second constantly?

For most practical purposes, they do. However, air resistance can greatly affect the acceleration of objects in freefall. Also, the acceleration due to gravity is a function of the distance between the objects. So, the gravitational force on an airplane of 30,000 feet is slightly less than that on a Baseball at 100 feet.

How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
How much force is needed to accelerate a 1-kilogram toy car at rate of 2 meters per second per second?
-1
What force would be needed to accelerate a boulder having a mass of 1800 kg by 3 meters per second per second?
5400 N
The force required to accelerate a 200 kg object 15 meters per second squared is what?
Newton's Second Law of Motion states that Force equals the product of mass and acceleration. Thus, the force required to accelerate a 200 kg object 15 meters per second squared equals 200*15. This is equivalent to 300 Newtons.
How long does it take on average for a human body accelerate to 78 mph in freefall?
Convert 78 mph to meters per second: 78 mph=35 meters/second The acceleration of earths gravity is 9.8 meters per second squared. This is constant. Therefore, using basic calculus, the velocity of a falling object is equal to 9.8 meters per second times the time it has fallen. 9.8*T=35 T=3.6 Thus, it takes roughly three and a half seconds for the average human body to accelerate to 78 miles per hour (assuming wind drag is inconsequential).
How would objects accelerate if they feel in a vacuum?
Depens on the amount of gravity. On Earth, they accelerate at about 9.8 meters per square second.
Gravity causes all objects to accelerate toward and earth at a rate of?
9.8 meters per second squared.
Do objects accelarate as they fall?
Absolutely! In fact, gravity is an acceleration associated with massive objects. If you drop your pen off of your desk, it will accelerate at 9.8 meters per second per second until it hits the ground.
What is the rate of speed in mph that all objects will fall at in a vacuum chamber?
Objects in a vacuum will NOT fall at a constant rate; they will fall faster and faster. In other words, they will continuously accelerate. The acceleration near the surface of the Earth is about 9.8 meters per square second. This is not a speed - it means that every second, the speed of the object increases by 9.8 meters per second.
How many meters per second does gravity accelerate an object's mass?
9.8 meters per second each second = 9.8 m/s2.
How fast do objects accelerate due to gravity?
On Earth 9.81metres/second^2
What law says that heavier objects require more than lighter objects to move or accelerate them?
second law
How much does the earth's gravity cause on an object to accelerate?
Assuming other forces, and mainly air resistance, can be ignored: about 9.8 meters per second squared. This means the same as 9.8 (meters/second) / second; so, every second, the velocity will change by 9.8 meters per second.
What are some results about big and small objects and which reaches the ground first?
In free fall an object regardless of its mass will accelerate at 9.8 meters/second/second or 32 feet/second/second assuming that you are on earth in a frictionless environment. This means that any two objects regardless of their mass will fall to the ground at the same rate.
How does an objects mass affect how it accelerates to earth?
It doesn't. Close to Earth's surface, any object will accelerate towards the center of the Earth at a rate of about 9.8 meters/second squared, regardless of the object's mass.
How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
How fast does gravity accelerate objects on Earth's surface?
It is approx 9.81 metres per second-squared.
