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.
What force would be needed to accelerate a boulder having a mass of 1800 kg by 3 meters per second per second?
5400 N
How much force is needed to accelerate a 1-kilogram toy car at rate of 2 meters per second per second?
-1
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).
Gravity causes all objects to accelerate toward and earth at a rate of?
9.8 meters per second squared.
How fast do objects accelerate due to gravity?
Objects in free fall accelerate at a rate of 9.8 m/s^2 (meters per second squared) due to gravity near the surface of the Earth. This acceleration is constant regardless of the object's mass.
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.
How would objects accelerate if they feel in a vacuum?
In a vacuum, objects would accelerate due to the force of gravity acting on them. The rate of acceleration would be the same for all objects, regardless of their mass, and would be equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 near Earth's surface.
How many meters per second does gravity accelerate an object's mass?
9.8 meters per second each second = 9.8 m/s2.
What causes objects to accelerate?
Gravity causes falling objects to accelerate.
How much does the earth's gravity cause on an object to accelerate?
The acceleration due to Earth's gravity is approximately 9.81 m/s^2. This means that any object near the surface of the Earth will accelerate at this rate towards the ground if no other forces are acting upon it.
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.
What is the rate of speed in mph that all objects will fall at in a vacuum chamber?
All objects will fall at the same rate of speed in a vacuum chamber, which is approximately 9.8 meters per second squared (m/s^2) or about 22 miles per hour (35 kilometers per hour) after one second of free fall.
What law says that heavier objects require more than lighter objects to move or accelerate them?
Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that heavier objects require more force to move or accelerate them compared to lighter objects.
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.
