## What determines the distance of a projectile?

A projectile is often thought of as having two independent and simultaneous motions – a motion in the horizontal direction and a motion in the vertical direction. The horizontal distance depends on two factors: the horizontal speed (vox) and the time the projectile has been in the air.

### What determines how long an object is in the air during projectile motion?

The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m/s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.

**What does projectile motion depend on?**

As has already been discussed, the vertical displacement (denoted by the symbol y in the discussion below) of a projectile is dependent only upon the acceleration of gravity and not dependent upon the horizontal velocity.

**What factors affect the distance a projectile travels and how?**

Factors affecting the flight path of a Projectile are:

- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.

## How do you determine the maximum height of a projectile?

h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.

### What is the formula for horizontal projectile motion?

Horizontal projectile motion equations Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.

**How do you determine how long an object is in the air?**

Use the vertical motion model, h = -16t2 + vt + s where v is the initial velocity in feet/second and s is the height in feet to calculate how long the basketball will be in the air for.

**How do you know how long something is in the air?**

To find the time of flight, determine the time the projectile takes to reach maximum height. The time of flight is just double the maximum-height time. At maximum height, vy = 0. The time of flight is also determined solely by the initial velocity in the y direction and the acceleration due to gravity.

## How does height of release affect projectile motion?

The higher the level of release, the greater the distance covered in flight. This is because the higher the projectile is released, the longer it will be in the air. The horizontal component will be acting on the projectile for longer. -As the height of release increases, the angle of release decreases.

### What are the two components of projectile motion?

There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.

**What factors affect the motion of a projectile How do these factors affect a projectile?**

FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.

**What are the parameters of projectile motion?**

The motion of such a particle is called Projectile Motion. In the above diagram, where a particle is projected at an angle θ, with an initial velocity u….Few Examples of Two – Dimensional Projectiles.
