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.
What else can I help you with?
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.
Why do astronauts feel heavier during launch?
Astronauts feel heavier during launch because of the upward motion of the spacecraft. This has the effect of adding extra "g's," or gravity forces, making everything seem heavier while the thrust is occurring.
How does a rocket ship take off from the ground?
A rocket ship takes off from the ground by igniting its engines to produce thrust. The thrust pushes the rocket upward, overcoming Earth's gravitational pull. As the rocket accelerates, it gains the speed needed to break free from the Earth's atmosphere and enter space.
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.
What direction would the stalactites and stalagmites be in?
The stalactites hang from the ceiling, and the stalagmites are on the ground.
A ball is thrown vertically upward what is the acceleration of the ball just before it hits the ground?
The acceleration of the ball just before it hits the ground is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 downward.
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.
What is the magnitude of the upward acceleration of the load of bricks?
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
How will the speed of a ball thrown upward and a ball thrown downward compare upon striking the ground?
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
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?
The acceleration of the object would still be g downward, regardless of the angle at which it is thrown upward. The acceleration due to gravity always acts in the downward direction towards the center of the Earth. The only difference would be the horizontal component of the velocity due to the initial angle of the throw.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
What does an upward sloping diagonal line mean in a velocity vs time graph?
An upward sloping diagonal line on a velocity vs. time graph represents constant acceleration. The steeper the slope, the greater the acceleration.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
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.
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)
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
The downward acceleration of the projectile released from the missile would still be due to gravity, which is approximately 9.8 m/s^2 on Earth. This acceleration is independent of the initial upward acceleration of the missile.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
