Gravity is a characteristic of space that causes a forceto appear between every
two masses, drawing them together.
If they're free to move, then each mass moves toward the other one because of the force.
Since the force on each one continues and doesn't stop, they keep coming together
faster and faster until they hit each other. That's called "acceleration".
If one of the masses happens to be the earth, then anything that's near it and
getting pulled toward it moves 9.8 meters per second faster every second than
it moved one second earlier. That's called the "acceleration of gravity" on or near
the earth.
If an object started out on the other side of the universe and got pulled all the way to
the earth by gravity, going faster and faster all the time, then by the time it got here,
it would hit the ground at a speed of 11,200 meters per second. That's about 25,000
miles per hour. If you want to launch a rocket or toss a ball fast enough so that gravity
can't pull it back to earth, that's how fast you have to toss it.

What is it when gravity and speed are balanced?
I assume you mean when the acceleration of gravity stops altering the velocity of a falling object. At this point the force of air friction is equal but opposite to the force of gravity, velocity stops increasing in magnitude. This is called "terminal velocity."
The speed an object reaches when the force of gravity is balanced by the force of air resistance?
Terminal velocity is the speed an object reaches when the force of gravity is balanced by the force of air resistance. At terminal velocity, the object no longer accelerates and falls at a constant speed. This speed varies depending on the mass, size, and shape of the object.
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
What is a situation gravity causes a change in velocity and why does the change of velocity happen?
A situation where gravity causes a change in velocity is when an object is dropped from a height. As the object falls, gravity acts on it, causing it to accelerate towards the ground. The change in velocity happens because gravity exerts a constant force on the object, causing it to increase its speed over time.
Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.

How do gravity and speed matter with velocity?
1. Gravity is acceleration. 2. speed is a scalar quantity. 3 . velocity is a vector quantity. In other words, gravity is the force which accelerates matter towards the centre of a mass. Speed is how fast something is moving in general. Velocity is speed in one direction. I suppose a link could be using the suvat equations with velocity and acceleration. But vector and scalar quantities don't mix very well.

What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
When an object reaches terminal velocity and there is no net force what is the initial force that got it going to keep it in motion?
Gravity. The object starts at zero velocity, and gravity always pulls the same. Drag, however, increases when velocity increases. Terminal velocity is when gravity has accelerated the object to the speed where drag is the same as gravity.
What is critical speed of pump?
Critical velocity is the speed that a falling object reaches when gravity and air resistance equalize on the object.when a liquid posses streamlined motion and its velocity is less than certain limiting velocity is called critical velocity for fluids and critical velocity for satellites can be defined as the velocity will give stable orbit, this is called the critical velocity for satellites

To escape from a planets gravity an object must reach a speed called the?

How using Earth's rotation speed to escape gravity?
Earth's rotation speed doesn't affect the ability to escape Earth's gravity. Escaping Earth's gravity requires reaching a velocity of about 11.2 km/s regardless of Earth's rotation speed. Earth's rotation does provide a slight boost to the velocity required to escape in the direction of the rotation.
What is it called when air resistance and gravity are the same?
When air resistance and gravity are equal, it is known as terminal velocity. At terminal velocity, an object falling through the air no longer accelerates but rather falls at a constant speed due to the balance between air resistance and gravity.
