what is the acceleration of a 1.4 kg object if the gravitational force pulls downward on it , but air resistance pushes upward on it with a force of 2.5 N?

if g = 10(m/s)/s then force down = ma = 10*1.4=14n
14n-2.5n=11.5n
a=f/m = 11.5/1.4 = 8.21 (m/s/)s

∙ 11y ago-- The gravitational force on a 1.4 kg object = m g = 1.4 x 9.807 = 13.73 Newtons.
-- If a force of 2.5 N acts against gravity, then the net downward force on
the object is 11.23 N.
-- 11.23 N = 81.79% of the object's weight, so its acceleration is 81.79% of the
gravitational acceleration = 8.02 meters per second2.

If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
a constant horizontal speed
Describe how the velocity and acceleration of an object change as it fell from tall building?
The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.
An object that is thrown vertically upward will return to its original position with the same speed as it had initially if air resistance is negligible if air resistance is appreciable?
As an object rises WITH air resistance, the acceleration is larger in size than g, because both gravity and air resistance will be causing a downward acceleration. As the object FALLS with air resistance, the acceleration will be smaller in size than g, because gravity and resistance will be opposing each other. Because of the smaller acceleration being applied over the same distance, the return speed will be slower than the launch speed.
Does A free falling object experiences a balance of forces?
Yes, if it reaches terminal velocity, which is a constant velocity. When terminal velocity is reached, the downward gravitational force is equal to the upward force of air resistance, and the object no longer accelerates.
What force opposes the downward motion of falling object?
Air resistance
When no air resistance acts on a nicely tossed basketball its acceleration is what?
It doesn't matter whether the object is a basketball or something else. If there is no air resistance, the acceleration due to gravity is 9.8 meters/second2, in the downward direction.
If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
a constant horizontal speed
Why is the mass of an object same on the moon as it is on earth but the weight is different?
Mass is the amount of matter in an object. It does not change based on gravity. Weight is the force an object exerts 'downward' due to gravitational acceleration. Force = (mass)*(acceleration). Acceleration due to gravity is less on the Moon than on Earth.

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.
How would you find the mass of an object if there were no gravitational force?
Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.

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.
Why would an object transported from earth to the moon have the same mass but different weight?
Gravity is different on the earth than it is on the moon. An object will weigh more on Earth since there is more gravitational pull on the object. However, mass isn't dependent on gravity, and in physics, the formula for Weight is W = ma. This means weight is dependent on the acceleration that an object has in a downward direction, and in this case, we would be focusing on gravitational acceleration that is applied to the object.
Can you calculate gravitational acceleration witn only having the time and the mass of the object?
Gravitational acceleration is always g = 9.8
What determines the size of gravitational force?
The mass of the object the force is acting on, and the gravitational acceleration where the force is acting. F = m*g, where F is the gravitational force, m is the mass of the object and g is the gravitational acceleration (on Earth it is about 9.81ms-2)
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.
