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 does the unbalanced force of gravity affect the horizontal and vertical velocities of an object in projectile?
In the absence of air resistance, the force of gravity has no effect on the horizontal component of a projectile's velocity, and causes the vertical component of its velocity to increase by 9.8 meters (32.2 feet) per second downward for every second of its flight.

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 the horizontal component of a projectiles velocity independent of time?
Yes, in the absence of air resistance, which is the way the situation is always viewed by everyone except Navy gunners.

Why is the absence of friction important when studying interacting objects?
The absence of friction makes it a 100% efficient space to see the reaction between any interacting objects.
What are the conditions required to swing continuously in air?
absence of friction...no air resistance
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.
How do you use friction daily?
Walking , if there is no friction you wont be able to walk properly . Another important thing is driving . In the absence of friction the car wheels wont be able to rotate probably thus the car will just go in circles.
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.
According to the work-energy theorem in the absence of friction if you do 100 J of work on a cart you'll increase its kinetic energy by?
100J
