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 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 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 the difference of speed from velosity?

Speed is a scalar, velocity is a vector. That is to say, when you talk about "speed", the direction doesn't matter; when you talk about "velocity", it does. A velocity is only completely specified if you know the magnitude AND the direction.


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.


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

Escape Velocity


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


How fast do you have to go for gravity not to take hold of you?

Speed does not matter- gravity will still have a pull.


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 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.
