Projectile motion in the y-axis refers to the vertical motion of an object that is influenced by gravity. It is the motion of an object that is thrown or launched into the air and follows a curved path due to the force of gravity acting on it.
The y-axis motion of a projectile is affected by the initial velocity, the angle of launch, and the force of gravity. These factors determine the height and distance that the object will travel in the vertical direction.
The velocity of a projectile in the y-axis can be calculated using the formula vy = v0y + gt, where vy is the final velocity, v0y is the initial velocity in the y-axis, g is the acceleration due to gravity, and t is the time taken.
The maximum height reached by a projectile in the y-axis motion is determined by the initial velocity and the angle of launch. It can be calculated using the formula h = (v0y)^2/(2g), where h is the maximum height, v0y is the initial velocity in the y-axis, and g is the acceleration due to gravity.
Air resistance can have a small effect on the y-axis motion of a projectile, but it is usually negligible. In most cases, the effect of air resistance can be ignored when calculating the trajectory of a projectile in the y-axis.
