No, a feather falling in a vacuum is not considered projectile motion. Projectile motion involves an object being launched horizontally with a certain velocity while experiencing the force of gravity, causing it to follow a curved path. In a vacuum, there is no air resistance or drag force acting on the falling feather, so it falls straight down due to gravity.
No, a ball on the ground is not considered a projectile. In physics, a projectile is an object that is in motion and is only subject to gravity and air resistance. A ball on the ground is not in motion and is not being acted upon by external forces.
In physics, the force of gravity is typically considered a negative force because it acts in the opposite direction to the motion of the projectile. Gravity causes the projectile to decelerate and move downwards.
The velocity of a projectile is considered to be constant when there is no change in speed and direction. This usually occurs in the absence of any external forces, such as air resistance or gravity, that could affect the projectile's motion.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
Projectile motion.
motion of a projectile
The horizontal component of a projectile follows uniform motion, meaning it moves at a constant velocity in the absence of air resistance or other forces. This motion is independent of the vertical motion of the projectile.
Gravity
To improve projectile motion, you can adjust the initial velocity, launch angle, or launch height of the projectile. By optimizing these parameters, you can achieve greater distance, height, or accuracy in the motion of the projectile. Additionally, reducing air resistance and wind can also help improve the overall projectile motion.
