Is it true when you drop from a branch to the ground below you pull upward on earth if so then why is the acceleration of earth not noticed?

Yes, it is true that when you free fall from any height you are exerting a gravitational force upon the earth. Gravitational forces are calculated based upon the mass of objects... The more mass an object has the greater its gravitational pull.
However, the mass of a person is so small in comparison to the mass of our planet that the amount of force you are pulling the earth with would be similar to measuring how much you can slow an ocean freighter by throwing a single grain of sand at it.
Basically, the amount acceleration of the earth towards you is SO small that I would be thoroughly impressed if it moved even a nanometer.

Where are stalagmites formed?
Stalagmites are formed on the floor or ground of the cave and are spikes facing upward.
Why can you jump higher on the moon?
When you jump, you exert a force greater than the force of gravity to achieve a net positive upward acceleration - at least until your feet leave the ground and you quit exerting force. The net upward force is Fnet = (force you push off with) - (force of gravity) Because the moon has less mass than the earth, the force of gravity is less. As a result, the force you exert to jump on earth would give a higher net upward acceleration on the moon and allow you jump higher.
How do you calculate the force that make an object mass rises to an distance vertically?
1). First of all, in order to make an object rise at all, an upward force must be applied to it, and the force must be greater than the object's weight. 2). If an upward force exactly equal to the object's weight is applied to it, then the object can "hover" wherever you put it, as if it is weightless, but it can't rise. 3). If the upward force is greater than the object's weight, then the object can rise to any desired height. It will continue to rise, and its speed will increase, as long as the upward force continues. 4). When the upward force stops, then the object will continue to rise, but it's upward speed will begin to decrease. When the upward speed decreases to zero, the object stops rising and begins to fall. It's downward speed then increases continually, until it hits the ground.
How does warm air moves?
it is pushed upward
How many degrees upward can a child see?
70
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
An object is dropped and falls to the ground with acceleration of g if its thrown upward at an angle its acceleration would be 0 larger than g g upward g downward or none of the above?
9.8 meters per seconds squared in the downward direction.
A cricket ball is projected vertically upward what kind of acceleration is acting on the ball?
a cricket ball is projected vertically upward direction.what kind of acceleration is acting on it
A ball tossed vertically upward rises reaches its highest point and then falls back to its starting point during this time the acceleration is always?
Pointed towards the ground
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
What is the upward acceleration of a falling object?
If you are ignoring wind and other variables then the upward acceleration is negative velocity caused by gravity. So in most cases (-9.8 m)/(s^2)
Do you agree with the statement an object with a zero velocity can have an acceleration greater than yero?
Of course. Toss a stone straight up. -- From the moment it leaves your hand until the moment it hits the ground, it has constant acceleration ... the acceleration of gravity, around 10 meters per second2. The number isn't important, only the fact that the acceleration of the stone is not zero until it hits the ground. -- Velocity-wise: The stone starts out with some upward velocity, which steadily decreases until it's at the top of its arc, then the velocity becomes downward and increases until the stone hits the ground. -- At the very top of the arc, there is a point where the velocity changes from upward to downward. In order for that to happen, there must be an instant when the velocity is zero. -- But the acceleration is constant and not zero, even at that instant when the velocity is zero.
What is the acceleration of a ball at the top of its trajectory when thrown straight upward?
zero
How does acceleration change when object is thrown veritcally upward under ideal conditions?
From the time the object leaves your hand, its acceleration doesn't change at all ... it remains constant at 9.8 meters (32.2 feet) per second2 downward. Well, we have to admit that the acceleration does change to zero once the object hits the ground.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
upword acceleration is -9.8 and downword is 9.8m/s^2
