What force is pulling down on the straw and clay ball?
gravity
What does pull a vacuume mean?
pulling out as much of the particals in a given space, as possible. when you put a finger on one end of a straw and suck on the other end the straw collapses; you are pulling a vacuum.
Why does a straw float in water?
A straw floats in water because it is less dense than water. The air trapped inside the straw creates buoyancy that counteracts gravity pulling it down, causing it to float.
The water in a drinking straw does not drip out when you press te top of the straw with your thumb or finger tip?
It's a matter of air pressure that acts on the water. When the straw is uncovered, there are two forces acting on the water inside. There is gravity, pulling the water down, and air pressure. The pressure is about the same on both ends of the straw, but on the top of the straw, the pressure pushes the water downward, and on the bottom of the straw, the pressure pushes upward. Both of the pressures are the same, so the net force is just the force of gravity pulling the water down and out of the straw. When you cover the top of the straw, you block the air from pushing down on the water. In this case, the only forces on the water are the air pressure pushing up, and gravity pulling down. However, the air pressure is a greater force than gravity, and keeps the water in the straw despite gravity's pull.
What would happen if you put a straw in a cup of water?
The straw will displace the water, causing the water level inside the straw to rise slightly. When you suck on the straw, you create a vacuum inside it, pulling the water up into the straw and allowing you to drink it without tilting the cup.
What is it called when water climbs up the straw due to adhesion?
Capillary action is the phenomenon where water climbs up a straw due to adhesion to the straw's surface, pulling the water along with it. This occurs because the adhesive forces between water and the straw are stronger than the cohesive forces within the water molecules.
What is the rebus puzzle straw straw straw straw straw straw straw?

My seven yr old asked if gravity play's a role in the movement of grass on the side of a road when a car passes?
A little. Gravity will try to pull every part of the straws down, the wake of the car will try to push them sideways. If a straw is perfectly upright, each part of the straw would be perfectly supported by the part underneath. But as the wake of the car push the straw sideways, gravity will then begin to help bending the straw by pulling each part of it down, and this time there's no straw under to help resist gravity.
What role does atmospheric pressure play when someone is drinking a liquid through a straw?
when you drink through a straw you remove some of the air in the straw. because there is less air the pressure of the straw is reduced. but the atmospheric pressure on the surface of the liquid remains the same. henceforth how it helps you drink
What do you call the paper left on a straw?
The paper left on a straw is typically referred to as a straw wrapper or straw sleeve. It is used to keep the straw clean and hygienic before use.
What was the one of the first polls used in American politics?
A Straw Poll
What force makes the straw and clay ball float even though there is a force pulling them Downow?
The force that makes the straw and clay ball float is buoyancy. Buoyancy is an upward force exerted by a fluid that opposes the weight of an object immersed in the fluid. This force is able to counteract the force of gravity, allowing objects to float.
