In summary, the x component of the initial velocity remains constant since there is no acceleration in the x-direction. At maximum height, the velocity is equal to v0cosθ0i. In a vacuum, there is no drag force or external factors affecting the x-component of velocity. However, in the real world, the drag force of air and wind direction would need to be considered in the calculation.

Yes it is. The ##x##-component never changes since there is no acceleration in the ##x##-direction. At maximum height, ##v_y = 0##, so ##\vec{v} = v_0 \cos{\theta_0} \hat{\imath}##.

Projectile motion velocity is the rate at which an object is moving in a specific direction at any given time during its motion. It is a vector quantity, meaning it has both magnitude and direction.

The formula for calculating projectile motion velocity is v = v_{0} + at, where v is the final velocity, v_{0} is the initial velocity, a is the acceleration, and t is the time. This formula can be broken down into components (horizontal and vertical) if necessary.

Yes, projectile motion velocity can change during flight due to factors such as air resistance, gravity, and external forces. However, in the absence of these factors, the velocity remains constant.

Initial velocity refers to the velocity of an object at the beginning of its motion, while final velocity is the velocity at the end of its motion. In projectile motion, initial velocity is typically the velocity at which the object is launched, and final velocity is the velocity at which it lands.

Yes, projectile motion velocity can be negative if the object is moving in the opposite direction of the chosen coordinate system. For example, if the positive direction is upwards and the object is moving downwards, the velocity would be negative.
