if its a velocity / time curve, it will show diminishing acceleration (slope of the curve) up to terminal velocity (forces balanced)
It depends on the shape of the object. A spherical object will fall faster than a rectangular object. This is untrue if they are placed in a vacuum.
In air, yes. In vacuum, no.
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
It has been known since the 16th century that the mass of an object is irrelevant to how far it will fall. The main factor influencing the rate of fall is the shape of the object and, therefore, the air resistance (or buoyancy).
yes in air or liquid. The shape determines the opposing force (friction) encountered. A flat object will fall in a tumbling manner, because the opposing force is mostly likely acting at a an angle to the fall and the angle is changing with the inclination of the object. Even a baseball will spin because of the unevenness of how friction acts on the surface facing down.
The shape of an object affects the rate at which it falls due to differences in air resistance. Objects with larger surface areas experience more air resistance and fall more slowly than objects with smaller surface areas. Objects with streamlined shapes experience less air resistance and fall more quickly.
It's all about the air resistance that the object receives as it falls in an atmosphere. The air has to move around the object as it falls, if it's allowed to move smoothly aroundyam object by the objects shape then the force of the air resistance is lower. This allows the object to fall faster.
in a vacuum, yes, all objects would fall at the same rate, but otherwise no due to air friction
Yes, objects fall towards the center of the Earth due to gravity. This is true regardless of the object's size, mass, or shape.
The graph is a straight line whose slope is the acceleration of gravity.
The rate at which an object falls through air is affected by factors such as its weight, the air resistance acting on it, its shape, and its surface area. Heavier objects generally fall faster due to gravity, while air resistance can slow down the fall of objects with larger surface areas or irregular shapes.
It depends on your point of observation. It may appear to curve if you are stationary with respect to the surface of the Earth, though with respect to the travel of the object it will (with ever-so-slight perterbations by the sun, moon, etc.) fall directly toward the center of the Earth.
