If you need a one word answer, then I think "buoyancy" is what you're looking for.
Buoyancy is caused by falling air pressure with altitude. Air pressure at sea level is over 14.7 pounds per square inch (2000 pounds per square foot!). You can feel this pressure by pulling on a suction cup. Because air pressure drops with altitude, the force from air on the top of an object is less than on the bottom. If the object has very low density (such as a helium-filled balloon), this difference in force is enough to push the object up.
What else can I help you with?
What are the forces exerted on a yoyo hanging motionless on a string?
The forces exerted on a yoyo hanging motionless on a string are gravity acting downward and tension in the string acting upward. These forces are balanced, resulting in a state of equilibrium where the yoyo remains stationary.
What is the maximum velocity and acceleration that can be found for a point on the string?
The maximum velocity and acceleration of a point on a string depend on the properties of the string and the forces acting on it. The velocity of a point on the string can be limited by factors such as tension and length of the string. The acceleration of a point on the string can be limited by factors such as the mass of the string and the forces acting on it. The maximum velocity and acceleration can vary depending on the specific situation and conditions.
What forces are acting on the kite?
The main forces acting on a kite are tension in the string or line that holds the kite in the air and aerodynamic forces such as lift and drag from the wind. Gravity also acts on the kite, pulling it downward.
What will be value of tension produced by two opposite forces acting on a string at opposite ends?
equal to zero because two opposite forces will cancel each other
What forces acting on the hanging pen?
When a pen is hanging, the main forces acting on it are gravity pulling it downward and tension in the string supporting it. Gravity creates a downward force on the pen, while the tension in the string provides an upward force to keep the pen suspended.

How do you make music with a balloon with a string?
first thats a stupid ? but anyway u just put air in the balloon and get a string and hold the balloon with the hand that you write with and the string with the other and on the bottom of the balloon you but the string on that part and yank the string as fast as you can!!
What forces acting on the hanging pen?
When a pen is hanging, the main forces acting on it are gravity pulling it downward and tension in the string supporting it. Gravity creates a downward force on the pen, while the tension in the string provides an upward force to keep the pen suspended.
What forces are acting on a hanging pen?
When a pen is hanging, two forces act on it - the upthrust and the force of tension in the string.
How many forces are acting on a simple pendulum?
At rest, tension in the string and weight of the bob are the two forces both equal and opposite. During its displaced position, the weight of the bod, tension of the string and restoring force all the three would act on it
Did the cat get sick after eating the balloon string?
Yes, the cat got sick after eating the balloon string.
What will be tension in string on which two forces of 1010N act horizontally?
You've specified that the two forces act horizontally, but you've said nothing about how they're arranged relative to the string. -- Are the forces pulling in opposite directions on opposite ends of the string ? -- Are the forces both acting at the same end of the string, with the other end tied to a wall ? -- Are the forces in the same plane ? If so, is the string also in that plane ? I can give you configurations in which the forces are horizontal, and the tension in the string is anything you want between zero and 2,020 N. In fact, if both ends of the string are fastened to walls, and the horizontal forces push on the center of the string and perpendicular to it, then you can create any tension you want in the string, up to the breaking limit of the walls.
What are the forces acting on a chain in tension?
The forces acting on a chain in tension are the tension force exerted by the chain itself, and any external forces applied to the chain. These forces work to keep the chain in equilibrium and prevent it from breaking or stretching beyond its limit.
What are 2 forces that are acting on a hanging object?
Two forces acting on a hanging object are tension, which is the force exerted by the string or rope holding the object up, and gravity, which is the force pulling the object downward towards the Earth.
