How fast is a projectile moving at the top of its trajectory?
At the top of its trajectory, a projectile's vertical velocity is momentarily zero, while its horizontal velocity remains constant. The speed of a projectile at the top of its trajectory can be determined by calculating the magnitude of its velocity vector using the horizontal and vertical components of velocity.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
Is it true that a projectile launched into space at any angle will have a constant horizontal velocity?
Yes, in the absence of air resistance, a projectile launched into space at any angle will have a constant horizontal velocity. This is because there are no horizontal forces acting on the projectile once it is launched.
How can the horizontal velocity of a projectile be described?
The horizontal velocity of a projectile remains constant if there is no air resistance or external forces acting horizontally. This means that the horizontal component of the projectile's velocity does not change throughout its trajectory, only its vertical component is affected by gravity.
What acceleration affects the motion of a projectile?
The acceleration of gravity affects the motion of a projectile. It causes the projectile to accelerate downward, changing its vertical velocity over time, while the horizontal velocity remains constant (assuming no air resistance). This acceleration determines the shape of the projectile's trajectory.

The acceleration of gravity affects the motion of a projectile. It causes the projectile to accelerate downward, changing its vertical velocity over time, while the horizontal velocity remains constant (assuming no air resistance). This acceleration determines the shape of the projectile's trajectory.
Projectile's vertical velocity component changes at a constant?
The vertical velocity component of a projectile changes at a constant rate due to the acceleration of gravity. This acceleration causes the projectile to speed up as it moves downward and slow down as it moves upward. The magnitude of the acceleration is constant near the Earth's surface, at approximately 9.8 m/s^2.
What do the horizontal motions of a projectile have in common?
The horizontal motions of a projectile are independent of its vertical motion. This means that the horizontal velocity remains constant and unaffected by gravity. Additionally, the horizontal distance traveled by a projectile is determined by the initial horizontal velocity and the time of flight.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.
Is a projectile velocity the highest velocity that can be reached?
No, a projectile velocity is the initial velocity at which a projectile is launched. The highest velocity a projectile can reach depends on factors such as air resistance, gravity, and propulsion force. In some cases, the velocity of a projectile can increase or decrease after it is launched.
In the absence of air friction does the horizontal component of a projectile?
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.
What is velocity of a considered to be constant?
horizontal
Is the vertical velocity of a projectile constant?
No, the vertical velocity of a projectile changes continuously due to the force of gravity pulling it downward. Initially, the vertical velocity may be at its maximum, but as the projectile rises, the velocity decreases until it reaches zero at the peak of its trajectory, after which it starts to increase again as it falls back down.
