imagine that all the air around you is puting pressure on you. Then, when you go into a fluid, you can feel the pressure of the air and the water. The deeper you go, the more pressure is on top of you and eventually, you will get crushed.
A force of 9.8 N is the force exerted on a 1 kilogram mass at rest by the force of Earth's gravity at sea level. So 10 N is the force of about a 1.02 kg mass (approximately 2.25 pounds force)This is a scalar measurement.
In order to impart the greatest momentum to an object, you should both exert the largest force possible upon the object in question and extend that force for as long as possible. This is so because the greater the force acting on an object results in a greater change in velocity, which in turn yields a greater momentum. In addition to exerting the largest force possible on an object, you should also extend that force over the longest period of time as possible, as the sustained force also produces more momentum. As p= m•v, the best method in obtaining the greatest amount for 'p' would be to manipulate either the 'm' or 'v' variables. Force= acceleration= change in velocity= MOMENTUM. Greater amount of time= MOMENTUM
the science of shaping objects to reduce drag so that fluids flow more easily around them
The principles of learning in your own words are that education can take place on a deeper level and topics can be more thoroughly explored. The reason for this is there is a deeper understanding of the learning material.
Maybe, a little more, if you follow the standard advice of drinking plenty of fluids.(By the way, I recommend this advice from personal experience, but I am not an MD.)
do you exert more force when you are further from the fulcrum
Fluids exert pressure on a container due to the weight of the fluid above it pushing down. This pressure is distributed evenly in all directions, causing the container to experience a force perpendicular to its surface. The pressure increases with depth, as more fluid weight is pressing down.
The objects with bigger masses exert more pulling force. However, even though all the matter around us exert a force, their masses are too small for them to exert a 'feelable' force. But yes, they do exert a force, but its negligible.
The amount of force you exert remains the same, but the distance over which you exert the force can affect the work done. If you exert a force over a longer distance, you may do more work because the force acts over a greater distance. If the distance over which you exert the force is shorter, the work done may be less.
Atmospheric pressure exerts more force on you if you are deeper than 10 meters. At 10m below sea level the atmospheric pressure is double that of on land and it increase with every 10 metres that you descend
If the object having some mass then for sure it exert a gravitational force.The more the mass the more will be gravity.
Fluids have a higher density than air and therefore exert more pressure than air.
in which situation you exert more force downward, standing or lying horizantilly?
Objects that weigh less exert less downward force due to gravity compared to objects that weigh more. Gravity acts on all objects equally, causing them to fall at the same rate regardless of weight. However, weight is a measure of the force of gravity acting on an object's mass, so objects with more mass will have a greater weight and exert a greater force on a surface when supported.
Yes, they have gravity. In fact, anything that has mass will have a gravitational force - the more mass a body has, the more gravitational force it will exert.

For every action, there is an equal and opposite reaction.Example: The flying motion of birds is a good example of the Newton's third law. The wings push the air downwards. In turn the air reacts by pushing the wings (and therefore the bird) upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air which is downwards is opposite the direction of the force on the bird which is upward. For every action, there is an equal and opposite reaction. Tricky Question: Consider what happens when a small car collides with a heavy truck. Does the truck exert more force on the car, or does the car exert more force on the truck? Answer: Neither. They both exert the same amount of force on each other (Newton's Third Law). The car's acceleration is more dramatic because the same force is being applied to a smaller mass.
