If, only the initial velocity in x direction is given and the total distance "S" is given for a non horizontal projectile, how do we find the y (vertical) component of initial velocity? No angle given?
The vertical component of velocity refers to the speed at which an object is moving in an upward or downward direction. It is one of the two components of velocity, along with the horizontal component, that describes the object's overall motion.
To calculate the vertical component of velocity, you will need to know the object's initial velocity, the acceleration due to gravity, and the time elapsed. You can then use the formula v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time, to calculate the vertical component of velocity.
The acceleration due to gravity is a constant value that represents the rate at which objects accelerate towards the Earth. On Earth, this value is approximately 9.81 m/s², but it can vary slightly depending on location and altitude.
Air resistance, also known as drag, can affect the vertical component of velocity by slowing down the object's descent. As an object moves through the air, the air molecules push against it, creating a force that opposes the object's motion. This force can decrease the object's vertical velocity, making it fall more slowly.
Yes, the vertical component of velocity can be negative if the object is moving in a downward direction. In physics, upwards is typically considered the positive direction, so any motion in the opposite direction (downwards) would be represented by a negative velocity. However, the magnitude (or size) of the velocity would still be positive.
