Consider how a projectile’s motion is affected by the air it travels through. In which dimension does the air affect the projectile’s motion, and how?(2 points)
The air affects the projectile's motion in the vertical dimension.
When a projectile is traveling through the air, it experiences air resistance or drag. This force opposes the motion of the projectile and acts in the opposite direction of its velocity. The air resistance affects the vertical motion of the projectile by slowing down its upward motion and increasing the time it takes for the projectile to reach its peak height. On the way down, air resistance also acts to slow down the projectile's descent, resulting in a lower vertical velocity when it hits the ground compared to in the absence of air resistance.
The air affects the projectile's motion in the vertical dimension. This is primarily due to the presence of air resistance, also known as drag. As the projectile moves through the air, the air resistance opposes its motion, resulting in a decrease in the projectile's vertical velocity. This, in turn, affects the trajectory and time of flight of the projectile.
The air affects the projectile's motion in the vertical dimension. When a projectile travels through the air, it experiences the force of air resistance, also known as drag. This force acts opposite to the direction of the projectile's motion and varies with the projectile's speed, shape, and cross-sectional area.
Air resistance affects the projectile's motion by slowing it down. As the projectile moves forward, the air molecules in front of it get pushed aside, creating a region of higher pressure in front and lower pressure behind. This pressure difference generates a force that opposes the projectile's motion. As a result, the projectile experiences a deceleration, causing it to gradually lose speed.
The effect of air resistance is most noticeable when the projectile is moving at higher speeds or has a large surface area perpendicular to its motion. For example, a feather will be more affected by air resistance compared to a dense metal ball of the same size when thrown in the air.
To study the specific impact of air resistance on a projectile's motion, you can conduct experiments by comparing the motion of a projectile in vacuum (where there is no air) to the motion in the presence of air. By analyzing the difference in trajectories, velocities, and time of flight, you can quantify how air affects a projectile's motion in the vertical dimension.
