Different shapes result in different resistances (force opposing gravity) on the object as it falls. An object will continue to accelerate as it falls, until the gravitational force is equivalent to this resistance. This is known as "Terminal Velocity." The lower the resistance is, the higher the resulting speed will be before this equilibrium is reached.
An object with a large surface area or volume (high wind resistance value) and low density (low gravitational force) will fall slower than an object that has a lower surface area (low wind resistance) with a higher density (high gravitational force).
e.g., A large hollow Styrofoam ball will fall much slower than a metal dart.
If a force is applied to an object, it will accelerate in the direction of the resultant force.
If an object ejects mass, it will accelerate in the other direction (because momentum is conserved).
In a vacuum it doesn't
A: Since acceleration involves the vector sum of all forces acting on a mass, and resistance to motion (air or fluid resistance, friction, etc) is part of that sum, then shapes that increase or decrease resistance do affect the acceleration of an object as they affect the sum of forces acting on it.
The greater the force the more acceleration there is.
Force = Mass x Acceleration (Newton's Second Law)
F = ma
Where force is measured in Newtons, mass in kilograms and acceleration in metres per second.
The larger the force on an object of a certain mass the greater will be its acceleration.
force = mass x acceleration
therefore if an objects force increases then it follows that the increase is due to an increase in acceleration?
In normal conditions: a moving bod's mass does not change. Hence any increase in Force can only be the result of increased acceleration.
In general, a greater surface area means there will be more air resistance. However, the exact shape may also matter - air resistance doesn't depend solely on the amount of surface.

acceleration slows and speeds up an object's motion. acceleration is the application of force in any direction on an object. it can cause and object to turn also. acceleration is defined as the rate of which and object's velocity changes.
Different shapes have different wind resistances, which will slow speed differently.

The shape does not have any effect on an objects inertia.
It does not.
The speed of an object sinking depends on its density and also on its shape: a 2-lb sphere would sink much faster than a 2-lb disk.
The force mainly responsible for giving celestial objects their round shape and keeping them in that shape is gravity. Gravity pulls mass inward toward the center, resulting in a spherical or nearly spherical shape for large celestial bodies such as planets, stars, and moons.
They are totally unrelated. Weight is basically the force of attraction between the Earth and the body. It doesn't depend on shape. Air drag depends on how fast a body is moving through air and depends on its shape. There is one interesting example : when a parachute, or even an object falls under gravity for long enough, it may reach a speed where the air drag equals the weight - and then further acceleration ceases and the speed is called the terminal velocity. The terminal velocity therefore depends critically on the shape, and the weight.
they are different words with the same meaning.
no
In air, yes. In vacuum, no.
it depends on shape and resistence as cat only falls at 100kph but humans have a max of 290 if shaped downward like a bullet
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.
The equation for speed or fast is v=at and the distance is d=1/2 at2 the acceleration is 'a'.
for how fast an object falls, use v=gt. g stands for the acceleration of gravity- 9.8 m/s2 v stands for speed t stands for time for how far that object falls, use d=0.5gt2 d being distance
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).

The shape of a candle affects how fast it burns because if you have a round candle it would be shorter than a cylinder. The smaller the shape the faster it burns.
It is Slope , Volume of flows , and Streamed Shape.
How fast an object is moving and its mass. Resources: Textbook
Whether an object falls quickly or slowly basically depends on its mass, and its air resistance. More mass will have the tendency to make things fall faster; more air resistance will have the tendency to slow it down. The air resistance depends, to a great extent, on the object's surface area; however, the shape of the object also plays a role.
The only way that the mass can change is if matter is added or taken away. The volume of a liquid can increase if heated, such as the liquid inside of a thermometer. The thermometer is sealed and no liquid gets in or out, so the mass of the liquid is unchanged. But when the temperature goes up, the liquid expands and is forced to go up the thermometer.
