In the absence of air friction does the horizontal component of a projectile?
It typically
What is the effect on the projectile motion when the diameter of the object is changed?
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
In the absence of air friction does the horizontal component of a projectile's velocity change as the projectile moves is this True False?
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
how do objects fall when there is no air resistance?
In the absence of air resistance (friction) objects will fall at the same speed. Hope this still helps :)
What type of path does a projectile follow in the absence of air resistance?
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.

What are the conditions required to swing continuously in air?
absence of friction...no air resistance

What happens when ZnCO3 is heated in the absence of air?
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.

Is there less friction in vacuum?
In an atmosphere, when an object moves through the air it experiences friction with the air through which it moves. In a vacuum, there is no air and therefore no friction with an atmosphere as the result of an object moving through space. However, if two surfaces are moving against each other, there would still be friction from that action, even in a vacuum. In fact, in the absence of air that kind of friction could be increased.
What happens when sulphur is heated in absence of air?
Sulfur is melted.

When an object is a projectile what happens to the x component of the velocity throughout its trajectory?
Depending on the shape, speed and change in attitude (especially a tendency to tumble) of the projectile its losses of speed at various instants along its trajectory could be quite considerable owing to friction. Under many conditions air friction is proportional to the fourth power of speed. Thus, the horizontal component of the trajectory could be subject to considerable loss of magnitude. As one would expect the shape of the projectile will affect it's path considerably too.
What is the combination of horizontal motion with constant velocity and vertical motion with constant acceleration?
That combination is called "projectile motion". In the absence of air resistance, its shape is always a parabola.
Is their a word for absence of air?
the absence of air is "vacuum"
