In freefall do all objects near Earth's surface have the same acceleration?

Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass.
The principle of the parachute is to increase the surface area of a falling object with respect to its mass.

What occurs when objects free fall near the Earths surface constant acceleration?
Yes, exactly. Free fall results in constant acceleration.
What is the importance of 9.81 in accelaration due to gravity?
9.81 is the acceleration due to the force of gravity experienced by bodies on or about the surface of the earth (nominally at sea level) the units are meters per second / per second, that is to say a stone dropped from a height will gain 9.81 m/s velocity for every second it falls (is in freefall) however , if you move from the earths surface , this figure will diminish, an example being : if you double your distance from the earths centre you will experience 1/4 of the acceleration (or force) you experienced at the surface
Where does gravity pull people and objects?
On the earths surface gravity pulls you down.
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
When you push UP on an object when object is stationary on earths surface you increase your weight when you push DOWN on an object when object is stationary on earths surface you decrease your weight?
No, your weight is just the acceleration due to the Earth's gravity,
The phase ten meters per second squared describes the?
The approximate acceleration of a body in freefall near the earths surface due to earths gravitational pull. The object in freefall gains 9.81 meters per second for every second that elapses (ignoring air resistance).
What occurs when objects free fall near the Earths surface constant acceleration?
Yes, exactly. Free fall results in constant acceleration.
What happens to objects that enter the earths atmosphere?
the objects which enter the earths atmosphere are being pulled down towards the earths surface due to the earths gravity. And so it leads to falling falling of large objects from the space on the surface of the earth.
What is the importance of 9.81 in accelaration due to gravity?
9.81 is the acceleration due to the force of gravity experienced by bodies on or about the surface of the earth (nominally at sea level) the units are meters per second / per second, that is to say a stone dropped from a height will gain 9.81 m/s velocity for every second it falls (is in freefall) however , if you move from the earths surface , this figure will diminish, an example being : if you double your distance from the earths centre you will experience 1/4 of the acceleration (or force) you experienced at the surface
What is the gravitational force on any object near the earths surface?
Force (newtons) = mass (kg) * acceleration (m/s/s) > Acceleration at earths surface radius = 9.82 m/s/s
What describes droplets that condense on objects at the earths surface?
Dew
What is makemakes gravity compared to earths gravity?
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
What is the moisture that coats objects close to the earths surface called?
dark ages

What is the acceleration of an object approaching the earths surface?
Because gravity is not uniform across the entire surface of the earth and the centripetal force varies noticeably with latitude, the acceleration varies from point to point on Earth. At different points on Earth, objects fall with an acceleration between 9.78 and 9.82 m/s2 depending on latitude, with a conventional standard value of exactly 9.80665 m/s2 (approx. 32.174 ft/s2).
When you push UP on an object when object is stationary on earths surface you increase your weight when you push DOWN on an object when object is stationary on earths surface you decrease your weight?
No, your weight is just the acceleration due to the Earth's gravity,
