Gravity

The displacement of x is the change in position along the horizontal axis, while the displacement of y is the change in position along the vertical axis. These displacements are typically measured in units such as meters or feet, and can be positive (movement in one direction) or negative (movement in the opposite direction).

Yes, gravity still affects a dead body as it would any other object of similar mass. Gravity causes the body to remain on the ground or floor, and it also plays a role in the eventual decomposition and settling of the body over time.

This question has been pondered indefinitely, mass attracts all other mass, thats a fact, but the essence of this phenomena, though exhaustively probed and tested, eludes a definitive answer, one latest viewpoint is that matter contracts space, inviting all other matter toward it.

Einstein proposed his theory of general relativity, which describes gravity as the curvature of spacetime due to the presence of mass and energy. This idea revolutionized the way physicists viewed gravity by incorporating it into the fabric of spacetime itself, rather than just a force acting at a distance. Einstein's equations predicted phenomena like the bending of light around massive objects and the existence of black holes, which have since been confirmed by observations.

- a leaf flutters down from a tree to the ground

- a tree dies and falls over

- a stream runs down hill

- glaciers slither down hill

- a bird descends gracefully to the ground when it stops flapping

- an animal stands motionless on the ground, and does not float away

- when rain or snow leave the cloud, they proceed to the ground

- when rain wears away soil, rocks roll down hill

- gravity drives convection; warm air and water rise; cool air and water sink

- gravity drives buoyancy; ice, leaves, and bloated deceased fish float

- gravity creates orbits; the planets and the moon have orbits and stay in them

Gravity affects a ball launched from a catapult by pulling it downward towards the Earth, influencing its trajectory and causing it to follow a curved path. The force of gravity acts as a constant acceleration on the ball, pulling it towards the ground as it travels through the air after being launched.

Gravity is typically measured using an instrument called a gravimeter. Gravimeters detect changes in gravitational force by measuring the acceleration of a freely falling object, such as a mass or a spring. The unit of measurement for gravity is the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth.

Gravity is a natural force that causes objects with mass to be attracted to each other. Size refers to the physical dimensions of an object, such as its height, width, and depth. Size can vary depending on the scale at which it is being measured.

Thrust is a specific type of force that propels an object forward, usually in the context of propulsion systems like rockets or jet engines. Force, on the other hand, is a more general term that describes any push or pull on an object, and it can have various orientations and effects.

Things sink in water when their density is greater than that of water. Water has a density of 1000 kg/m3, rock exceeds this by a significant amount. The principle at work is that things sink if they water tey displace weighs less than the mass of the object.

What is registered on the scale is weight or force, at the earths surface 1 kg mass = 1 kg weight, if you put 1 kg mass on the scales at two earth radius,

it would weigh 0.25 kg

Equation concerned is: force = mass * acceleration due to gravity

A funhouse mirror is a type of mirror that distorts your image in funny ways to make you appear tall and thin or short and wide. This effect is achieved by the mirror's curved and uneven surface, which reflects light in distorted patterns. Funhouse mirrors are commonly found in amusement parks or carnival attractions for entertainment purposes.

No, wind is the result of a pressure gradient force between areas of high and low pressure. Wind always flows from high to low pressure, but the rotation of the earth creates a coriolis force which turns the wind to the right of expected motion in the northern hemisphere and to the left in the southern hemisphere. The resultant wind is parallel to lines of equal pressure in the upper atmosphere, but friction plays a factor closer to the surface as it slows down the wind speeds, subsequently weakening the coriolos force and turning the wind towards the low pressure in all instances. Therefore, wind will always flow cross-isobarically, that is across isobars (lines of equal pressure) towards lower pressure.

The value of acceleration due to gravity was first accurately measured by Galileo Galilei in the late 16th century through his experiments with falling objects.

Things roll downhill because of gravity, which pulls objects toward a larger mass, such as the center of the Earth. As an object gains momentum rolling downhill, the force of gravity helps it maintain its motion and accelerate. Friction also plays a role in ensuring the object stays in contact with the surface as it rolls downhill.

yes, by creating an opposing acceleration equal to the gravitational field strength (9.81m/s2) this would balance out the force of gravity and u could float. It can be done with magnetism, or with centripetal forces

A black hole is invisible because its gravity is so strong that not even light can escape from it. This phenomenon is known as the event horizon, which marks the point of no return for anything crossing it.

Yes, gravitational force is the attraction between two masses due to their mass alone, while magnetic force is the force exerted between magnets or moving charges due to their magnetic properties. Gravitational force follows an inverse square law, while magnetic force follows more complex laws described by Maxwell's equations.

If the force of gravity would suddenly stop acting on the planets, they would all move in straight lines tangential to their current path (meaning, due to their momentum, they would keep moving straight and not keep on being turned and pulled toward the sun). To see an example, take a yo-yo by the string and start spinning it around over your head. When you let go, you will see the object continue in a straight line which is a tangent to the position of the circle it was in while you were holding on to the string.

Yes, gravity affects the normal force between two surfaces, which in turn influences the frictional force between them. In general, an increase in weight due to gravity can increase the frictional force between two surfaces.

Gravity affects your driving by influencing how your vehicle accelerates and decelerates on uphill and downhill slopes. When driving uphill, gravity can cause your vehicle to lose speed and require more power to maintain momentum. When driving downhill, gravity can cause your vehicle to gain speed, requiring you to use your brakes more to slow down. Coast down hills to save fuel, and anticipate stopping distances when going downhill as it may take longer to stop due to the increased momentum.

The two quantities that affect the force due to gravity are the mass of the objects involved and the distance between them. The force of gravity increases with the mass of the objects and decreases with the square of the distance between them.

A circular parachute shape is typically the most effective because it provides stability and reduces oscillation during descent. The round shape allows for more controlled air resistance, aiding in a safer and slower descent. Additionally, circular parachutes are easier to pack and deploy.
