It depends on the shape of the object.
Mass is both a property of a physical body and a measure of its resistance to acceleration.
The amount of kinetic energy an object has depends on its mass and speed.
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.
-- the magnitude and direction of the force acting on an object -- the mass of the object being forcefully acted upon
The scientific definition of weight is that it is the the force of gravity acting on an object.

Usually gravity AND air resistance.
Gravity and air resistance.
Speed, shape and frontal cross-section. Viscosity, texture, friction, gravity, velocity, size, and shape can all affect air resistance.
Air resistance and gravity.
No, that is false. "Free fall" means that the only force acting on an object is GRAVITY. Specifically, there may be no significant amount of air resistance. It's not quite possible for the only force acting on an object to be air resistance, since you can't really eliminate the effect of gravity. Though, if the object has the same density than the liquid or gas in which it is placed, the gravity may be cancelled for practical purposes.
Mass is both a property of a physical body and a measure of its resistance to acceleration.
True (:
The forces acting on a falling body are gravity and air resistance.
