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.

In the absence of air friction does the horizontal component of a projectile?
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
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.
Sliding along the horizontal table is an example of projectile motion?
Sliding along a horizontal table does not involve projectile motion. Projectile motion refers to the motion of an object that is thrown or projected into the air and moves under the influence of gravity. In the case of sliding on a table, the motion is typically influenced by friction rather than gravity.
Is the vertical motion of a projectile dependent on its horizontal motion?
They fall at the same rate. So if you aim at an object before it falls from a height and shoot just as it is released then the projectile will hit the falling object. This happens because gravity is always the same (at small heights) and has the same effect on the object with no horizontal displacement as it does on the projectile with horizontal displacement.

How does air friction affect the path of a projectile?
Air friction acts as a resistive force on a projectile, slowing it down and reducing its speed. This can cause the projectile to deviate from its intended path and fall short of its target as the air friction dissipates its kinetic energy. The magnitude of the effect depends on factors such as the projectile's speed, shape, and surface area.
Is friction inertia's component?
Yes, because the friction is the same for the component of inertia.
What are the horizontal friction coefficient calculations?
The horizontal friction coefficient can be calculated using the formula: μ = F_h / N, where μ is the friction coefficient, F_h is the horizontal friction force, and N is the normal force acting on the object. The horizontal friction force can be calculated as F_h = μ* N, where N is the normal force and μ is the friction coefficient.

Which force will be needed to roll a barrel on a floor?
If you apply it at the top of the barrel, it's horizontal component needs to be opposite to and with greater magnitude than static friction. If you apply the force on some other spot with vertical distance d from the center of rotation the horizontal component of the force you need to apply is F=-1.5*T*R/(2d+R) where T is the friction and R the radius of the barrel.
What type of motion is the horizontal motion of projectile?
All projectiles move like a parabola. To solve for projectiles we refer to the equations of motion. There are 3 equations which are commonly known as the Kinematic Equations 1) Velocity as a function of time V = V_0 + a * t 2) Displacement as a function of time X-X_0 = V_0*t + 1/2 a * t² 3) Velocity as function of position V² = V_0² + 2 a ( X - X_0) We can rewrite EQ2 for horizontal motion X = X_0 + V_0 * t + 1/2 a * t² Because there is no gravity horizontally there is no horizontal acceleration. The ONLY acceleration would come from friction with the air. In most basic phsyics courses we say frictional force is negligible. If space was more fluidic this would be different, however it is not considered to be. Thus we have X = X_0 + V_0 * t What this equation tells us is... If we know the initial velocity when the projectile is launched then we can calculate its new position horizontally because the velocity was constant. We simply multiply the time to the velocity to get a distance traveled. Then add that distance to the initial position of the object to get its current location with respect to where it used to be.
What happens to a projectile in the absence of air friction?
In the absence of air friction, a projectile will follow a predictable parabolic trajectory determined by its initial velocity and launch angle. The projectile will continue to move freely in a straight line unless acted upon by an external force like gravity.
