**Horizontal**direction:

**Air resistance would**cause a

**horizontal**acceleration, slowing the

**horizontal**motion, but since we're going to only consider cases where

**air resistance**is negligible we can assume that the

**horizontal velocity**is constant for a projectile. [Will we ever get to consider

**air resistance**?!]

Simply so, does air resistance affect horizontal distance?

There are no forces acting on a projectile in the **horizontal** direction (neglecting **air resistance**), therefore the velocity is constant. The horizonatal velocity and the vertical velocity are independent of each other. One **does** not **affect** the other.

Likewise, how does air resistance affect the path of a projectile? Objects moving through **air** are slowed down due to **air resistance**, sometimes called **drag**. This **air resistance affects** a spacecraft when it re-enters the Earth's atmosphere but also the **path of a projectile** such as a bullet or a ball. The maximum height, the range and the velocity of the **projectile** are all reduced.

Simply so, how does air resistance affect velocity?

When **air resistance** acts, acceleration during a fall will be less than g because **air resistance affects** the motion of the falling objects by slowing it down. **Air resistance** depends on two important factors - the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.

Does horizontal velocity affect time?

The length of the **horizontal velocity** vector doesn't change. THE VERTICAL & **HORIZONTAL** MOTIONS ARE INDEPENDENT. THE **HORIZONTAL VELOCITY DOES** NOT **AFFECT** THE VERTICAL MOTION. THE VERTICAL FALL **TIME** IS THE SAME AS LONG AS THE BALLS DROP SIMULTANEOUSLY FROM THE SAME HEIGHT.
