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.

∙ 15y agoNo, the projectile accelerates in the vertical direction, due to gravity, but not at all in the horizontal direction. The projectile's horizontal velocity will remain constant as long as air resistance is negligible.

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.
When a railroad train rounds a banked track the centripetal force needed comes not from friction but from the?
horizontal component of the normal force.
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.

Is friction inertia's component?
Yes, because the friction is the same for the component of inertia.

How does science have to do with baseball?
projectile motion (vertical and horizontal motion) when the pitcher throws the ball and when the batter hits it.plus friction when people slip. and air resistance, and force of the ball, and action-reaction forces
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 is mechanical advantage of a inclined plane?
The forces are divided into a horizontal and a vertical component, so that you do not have to lift the weight in full directly. The disadvantage is that you get more friction, so that part of the advantage is negated.
With out air pressure at what point or points in its path does a projectile have its minimum speed and its maximum?
Without air friction, the horizontal component of the velocity will be constant. The vertical component of the velocity will be a maximum at the lowest point in its motion and at a minimum at the highest point in its motion. Therefore the minimum is at the highest point in its motion- Potential energy max Kinetic Energy min and the maximum is at its lowest point in the motion- KE is max PE min
Does the slant of an uneven surface create friction between the object and the surface?
What happens is gravity is pulling an object down, and if the surface it's resting on is slanted or uneven, there is a horizontal component to the force. That horizontal component attempts to move the object, however what CREATES the friction is the coefficient of kinetic friction (if the object is moving) or coefficient of static friction (if the object doesn't actually move) of the two surfaces. The two surfaces being the surface of the object that's touching the slanted surface and the slanted surface itself. These coefficients are determined by what the two surfaces are made of. Long story short, what CREATES the friction is the two materials touching each other. The slant just provides the force that attempts to move the object thus resulting in a visual representation of "friction."
Is the coefficient of friction on a horizontal plane between to substances the same as the coefficient of friction on the incline plane?
