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 else can I help you with?
If you throw an object towards the ground would it acceleration be greater or less thatn an object free falling?
Both objects would eventually reach terminal velocity which means they would both fall at the same speed.- But - compared to the falling object, the downward acceleration of a thrown object is the same.
What happens to the acceleration of an object as its mass decreases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
If you increase the force on an object what happens to the acceleration?
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
What is termanal velocity?
Perhaps you mean terminal velocity. This is the maximum velocity reached by an object falling to the ground when the acceleration due to gravity is matched by the drag resistance of the air through which it is falling.
The acceleration of an object depends on the force exerted on which of these?
an object's mass
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
The acceleration of a falling object is cause by the force of?
Gravity
What is the acceleration of a falling object caused by?
Newton's Second Law of Acceleration says it is gravity.
What balances the gravitational attraction of the earth on a falling object?
acceleration
The acceleration of a falling object is caused by th force of?
Gravity
What acceleration does the object reach when air resistance equals the force of gravity on a falling object?
the acceleration of gravity is 9.8 m/s
Examples for acceleration?
speeding of car speeding of a free falling object.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
What is constant for freely falling body?
The acceleration due to gravity is constant for a freely falling body. This means that the object will experience a constant acceleration of 9.81 m/s^2 (on Earth) in the downward direction, regardless of its mass. This allows us to predict the motion of the object using equations of motion.
What are the two characteristics of a free-falling object?
Constant acceleration and no air resistance are the two characteristics of a free-falling object.
What is the rate of acceleration of an object on the moon?
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
