Gravity

Yes, the gravity of all objects, no matter how big or small, can be felt to some extent. However, the strength of the gravitational force experienced diminishes with distance and mass, so smaller objects or objects farther away have a weaker gravitational effect.

Gravity is the property of space and matter that causes a pair of forces between
every pair of objects, attracting them toward each other. Depending on what other
forces may be around, and on the objects' relative motion, their response to the
forces may be to stay where they are, accelerate toward each other, sail past
each other on curved paths, or enter orbit around their common center of mass.

The translation of Sir Isaac Newton's works from Latin to French was done by the French mathematician François Jacquier. He translated Newton's seminal work "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy) into French in the 18th century.

Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.

Well, the formula for the gravitational force between any two objects says that

the force is proportional to the product of their masses, so we suppose that if

one of the objects had no mass, the product would be zero, and the force would

also have to be zero. Tell you what: You find us an object without mass, and

we can check it out together.

Gravitational force can be related to basketball by the simple fact that gravity is what causes the ball to go in the basket (of course if you shoot it right) after you shoot and also allows you to dribble.

A magnet attracts another object due to its magnetic field, which is a force that pulls certain materials towards it. This attraction occurs because of the alignment and movement of the magnetic domains within the magnet and the object, creating a magnetic force between the two.

Water defies gravity through two main mechanisms: cohesion and adhesion. Cohesion is the attraction between water molecules, allowing them to stick together and form droplets that can resist gravity. Adhesion is the attraction between water molecules and other surfaces, allowing water to climb surfaces, such as plants, through capillary action.

The force applied by a machine to overcome resistance due to gravity or friction is known as the applied force. Applied force is the amount of force needed to move an object against a resisting force, such as the force of gravity or friction. This force is usually measured in Newtons (N).

• When an object is stationary, the applied force is equal to the resisting force.
• When an object is moving, the applied force must be greater than the resisting force in order to maintain the object's motion.
• If the applied force is too small, the object will slow down and eventually stop.
• If the applied force is too great, the object may accelerate or move too quickly.

In order to determine the applied force, the resisting force must first be calculated. This can be done by multiplying the mass of the object by the acceleration due to gravity. The resisting force due to friction can be calculated by multiplying the normal force of the object by the coefficient of friction between the object and the surface it is in contact with.

It is still called water. The phenomenon that it's demonstrating

is called capillary action.

take g = 10 m/s^2 , u = 0 in all cases ,measured from same datum

s=(10*t^2)/2

if t = 1 second then s = 5 metres

if t = 2 seconds then s = 20 metres (2* time = 4*distance)

if t = 3 seconds then s = 45 meters (3* time = 9*distance)

if t = 4 seconds then s = 80 meters (4* time = 16 * distance)

but distance travelled between

secs metres

Electromagnetic force is greater because in microscopic theories usually gravitational force is neglected and we can attract a pin from the ground by electro magnet easily yet smaller in size, both acts at the vast range but electromagnetic force is far more greater then gravitational.

yo holmes, you are currently warping spacetime by existing. This bend is what is creating the gravitational pull you are experiencing. Have you considered inverting your spacetime warpage? Try bending space the other way, and see what happens. Now you're doing science, homeskillet. Tell the physicists of the world how it goes.

Gravity is vital because it keeps objects grounded on Earth and helps to maintain the structure of the universe. It plays a crucial role in the formation of stars, planets, and galaxies. Without gravity, life as we know it would not exist.

Birds are able to fly because of a variety of specialized adaptations. They have high metabolisms to supply their body with energy. They have lightweight bones. They have feathers, some of which are "flight feathers" that are long, strong, and able to produce lift and act as control surfaces. They also have a bone called the furcula, more commonly known as the "wishbone," in their chest, which is very important for being able to produce the strength and skeletal support needed to flap their wings.

The mechanics of flight are not unlike an airplane; the factors of lift, weight, thrust, and drag all interact to allow for controlled flight. By flapping their wings, birds create thrust and lift. They are able to steer by changing the shape and orientation of their wings and tail. They change the shape of their wing between the upstroke and downstroke as they flap to minimize drag on the upstroke and maximize the thrust generated downard on the downstroke, providing both lift and thrust. <><><> When all the feathers in a bird's wings are set in a certain way, so that the air cannot flow through them, the wing takes up a special shape which makes the air flow much faster over the top surface of the wing than it flows below the under-surface of the wing when the bird is gliding through the air. The difference in air-speed between the top and bottom surfaces of the wings gives the wings a "lift" force which can easily counteract the force of gravity.

Birds also have very powerful muscles to power their wings, which means they can flap their wings so fast that they can actually take off from the ground and move forward through the air, as well as glide "on" the air.

A very important fact is that a bird's wings are made of feathers. The feathers are not just ornaments! A bird can make its set of feathers close tightly together, which, when gliding or flapping, forces the air to flow around their top and bottom wing surfaces to give "lift", or it can make its set of feathers "open up", which allows the air to pass straight through them and, therefore, the wing, which allows the bird to fall under the force of gravity.

So, because a bird can set its wing feathers to be in any of a vast number of intermediate positions between "feathers fully open" and "feathers fully closed" - not just feathers fully closed for the start of a "flap" going to fully open before the end of a "flap", as would be necessary whilst flapping to take off - a bird can take off, glide, swoop down, glide again and then rise up again or drop, just as much as it wants to do!

for a given weight (force), reducing the contact area ie thinner strap, increases the pressure proportionally

pressure (pascals) = force (newtons)/ contact area (m^2)

half the area = twice the pressure

weight of bag * 9.81 = downward force in newtons

The force of gravity acting on the woman would be equal to her weight, which is 500 N. This is because the force of gravity provides the necessary force to keep her "weight" balanced on the Earth's surface.

Gravity pulls toward the center of the Earth due to the mass of the Earth creating a gravitational force that attracts all objects toward its center. This force acts equally in all directions, but because the Earth is spherical, the net effect is a pull toward the center.

~9.81 m/s^2

Force of gravity is a pull force. Earth has this force. The earth pulls us towards its center so that we are standing on it. If it was to push we would be in space now.

It is the mass of the earth itself that generates the gravity of earth. Every bit of matter in the earth adds to the gravitational pull that every object on the earth feels. In turn, the masses of our bodies have their own gravity, and our bodies and the earth exert a mutual pull. Earth is more massive, so it wins (we move toward earth; earth doesn't move toward us). For very large objects like the moon, the mutual pull is a little more cooperative. Earth and moon actually both orbit around a mutual point. If the moon and earth were the same mass, they would each orbit around a point half-way between them. They would do a kind of spiral dance together as they orbit around the sun.

Gravity plays a significant role in liquid splatter by causing the liquid droplets to fall towards the ground in a characteristic spray pattern. The extent of splatter can be influenced by the height from which the liquid falls, its viscosity, and surface tension.

It pulls you to its center or core. Ex. If digging a hole to China (actually impossible) you would first start by digging downwards but after you pass the core or center you'd be going upwards.
