Acceleration of a falling object?
The acceleration due to gravity for an object near the surface of the earth is approximately 9.81 m/s^2, but we can generalize this to "all falling objects" by defining falling as being attracted toward more massive object by gravitational force alone. The attractive force between the objects in this case is described by Newton's law of universal gravitation: F = G*m_1*m_2/r^2 where G = 6.67*10^-11, m_1 and m_2 are the masses (in kilograms) of the two objects, and r is the distance (in meters) between the centers of mass of the objects. The units of G are a little complicated, but this expression simplifies to units of meters/second^2, which is acceleration. Because the mass of a planet is so great compared to the mass of any object on its surface, the value of F does not change by a significant amount whether the falling object is a whale or a bowl of petunias.
What are the 2 forces that able an object to stay in orbit?
There are two forces responsible for an object to stay in orbit Namely-- 1-Centripetal Force --Which pulls any object toward the center 2-Centrifugal Force --Which push any object away from the center
What is the relationship between free-fall acceleration and mass?
The rate of free-fall acceleration is a constant based upon the local gravity - on planet Earth the acceleration is 9.8m/s2. Mass is a function of the object being measured or observed, which can vary considerably. The two do not directly affect each other, but both taken together determine the force of the object in free-fall - by knowing the free-fall acceleration and the mass of the object, you can calculate how hard it will impact the Earth.
What are two disadvantages of timber knots?

How gravity and air resistance are related to an object's terminal velocity?
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.
What are the two characteristics of a free-falling object?
there arent any.
What two-word term is the top speed reached by a free-falling object?
terminal velocity
Does an free falling object has an frictional effect?
To be very technical and precise, the answer consists of two parts: 1). No. 2). Outside of laboratory conditions, there can be no free-falling objects on Earth. "Free falling" means that there is no other force on the object except the gravitational one, so there's no friction acting on it. But this situation is impossible on Earth, because anything that falls is falling through air, so it does have friction acting on it ... called "air resistance" ... and it's not free falling.

What keeps a falling object from accelerating?
Air resistance and buoyant force are two factors that can oppose the acceleration of a falling object. These forces act in the opposite direction to the force of gravity, thus slowing down the object's acceleration.
What are two forces that affect an object falling?
-- gravity -- air resistance
The two force acting on falling object are gravity and?
air resistance.
What two characteristics can make the velocity of an object change?
Two characteristics that can make the velocity of an object change are the presence of an external force acting on the object and the object's mass. The direction and magnitude of the force, as well as the mass of the object, will influence how the velocity changes.
The two forces acting on a falling object are gravity and what?
The two forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward, while air resistance acts in the opposite direction to slow down the object as it falls through the air.
What is it called when two or more equal forces act on an object?
falling objects.
What two forces are acting on an object that is falling?
The two forces acting on an object that is falling are gravity, which pulls the object downward towards the center of the Earth, and air resistance, which opposes the object's downward motion and slows its fall.
Forces acting on a falling object?
Gravity: The pull of two objects on each other.Inertia: Basically something that slows any kind of acceleration or deceleration on a moving object.Yup, those two are the main forces that act on a falling object.
