Smoke is less dense than the air so by buoyancy in fluid (air) it moves upwards.

What is the answer to the brain teaser economy going upward?

Economy going downward.


Why do falling objects move faster than objects going upward?

Falling objects are accelerated by gravity, while objects moving upward are being decelerated by gravity. Gravity pulls objects downward, increasing their speed, while it opposes the motion of objects moving upward, decreasing their speed.


Why things thrown upward goes back to the ground?

Because they are in Earth's gravity well. They would have to move much faster than you can throw them to keep going up instead of falling back down.


Toss a ball upward what is the change in speed each second on the way up and on the way down?

The change in speed each second when the ball is tossed upward will decrease by 9.8 m/s each second due to gravity until it reaches its highest point and starts falling back down. On the way down, the speed will increase by 9.8 m/s each second as gravity accelerates the ball towards the ground.


When a plane is going ascending what forces act upon it?

When a plane is ascending, the force of lift generated by the wings must overcome the force of gravity pulling the plane downward. The engine also provides thrust to power the plane upward. Additionally, air resistance (drag) influences the speed and efficiency of the ascent.


Why do you think downward communication is much more prevalent than upward communication in security organization?

Downward communication is more prevalent because in this type of communication we have to give orders and instructions to our sub-ordinates. So we have to explain each and every step that is going to help in work.But in upward communication they sub-ordinates do not have to give instructions the their Head..


What is the name given to a force going down?

The force that acts downward is called gravity. It is the force that pulls objects toward the center of the Earth.


What is downward spiral?

no good out of it, everthing is or going bad, its going in a downward spiral.


Why does the ball thrown level to the ground move downward?

A ball thrown parallel to the ground moves downward toward the surface of the Earth because of the force of gravity.


What are the two forces acting on you in an elevator?

1). The force of gravity attracts you downward. 2). The floor of the elevator car exerts an upward force on the bottom of your feet. When #1 is greater than #2, you accelerate downward, and you feel lighter than normal. That happens when the car is starting to go down, or finishing going up. When #2 is greater than #1, you accelerate upward, and you feel heavier than normal. That happens when the car is starting to go up, or finishing going down. When #1 and #2 are equal, you don't accelerate at all, and your weight feels normal. That happens when the car is standing still, or rising at a steady speed, or dropping at a steady speed.


When a ball is thrown straight up into the air when the does the acceleration change directions?

Any object near the surface of the earth and not constrained experiences a downward vertical acceleration of 9.8 meters (32.2 feet) per second2 because of the mutual force of gravitational attraction between it and the earth.


Why do you feel heavier going up a lift?

The force of the lift accelerating you upward is added to the force dur to gravity. You feel this as added weight. The same effect happens when it stops moving going downward, and the opposite occurs when you begin going down or stop going up. You are not resisting the force of gravity and you do not feel the weight; for some of that time, you are actually freefall.
