Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
Why is an object considered weightless when there is no normal force or when an object is in freefall?
An object is considered weightless when there is no normal force acting on it because weight is the force exerted by gravity on an object's mass. In freefall, the object is only subject to the force of gravity, which causes it to accelerate with the same acceleration as the object itself, resulting in a sensation of weightlessness.
What is the only force on an object in freefall?
The only force acting on an object in freefall is gravity. This force causes the object to accelerate downward towards the Earth.
When is an object that has been dropped from a great height to the air closest to being in freefall?
An object is closest to being in freefall right before it hits the ground, when air resistance has slowed it down such that its acceleration is primarily due to gravity. At that point, the object's speed is nearly constant and it is falling solely due to the force of gravity.
What is the value of acceleration of an object in freefall?
If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)

What is the difference between freefall and a non freefall?
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
How does newtons second law related to gravity?
Newton's second law of motion states that the force acting on an object is equal to the object's mass multiplied by its acceleration (force = mass x acceleration). In the case of gravity, the force of gravity acting on an object is directly proportional to the object's mass. This means that the force of gravity on an object is equal to the object's mass multiplied by the acceleration due to gravity.
An object in freefall accelerates at a constant rate of velocity?
An object in freefall accelerates at a constant rate due to the force of gravity acting on it. The acceleration due to gravity on Earth is approximately 9.81 m/s^2, causing the object's velocity to increase by this amount every second.
If an object is droppes how fast is it traveling after 1 seconds?
In freefall, an object's velocity at a certain time can be calculated using the equation v(t)=a*t Where a=acceleration. On Earth's surface, acceleration due to gravity is equal to 9.8 m/s^2
How are weight and gravitationa force related?
Weight is the force exerted on an object due to gravity. It is proportional to an object's mass and the acceleration due to gravity. The formula to calculate weight is weight = mass x acceleration due to gravity.
How are mass weight and acceleration related to gravity?
Gravity is the force that attracts two masses together. Weight on Earth is the force of gravity acting upon an object on Earth. The formula for force is: F=ma -or- Force=mass x acceleration So, multiplying an object's mass by its acceleration due to gravity (9.8m/s2 on Earth) will give you the measurement of the force of gravity acting upon the object, also known as the object's weight.
How is force related to acceleration and gravity?
Force is directly proportional to acceleration, according to Newton's second law (F = ma), where F is the force applied to an object, m is the mass of the object, and a is its acceleration. Gravity is a type of force that can cause acceleration, as in the case of free-falling objects where the force of gravity causes the object to accelerate towards the Earth.
