## What are the two equations for 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.

Quantity | Value |
---|---|

Equation of path of projectile motion | y = (tan θ0)x – gx2/2(v0cosθ0)2 |

## What are the two vectors of a projectile?

– The horizontal component of the velocity. This is how fast the object is moving horizontally. – The vertical component of the velocity. This is how fast the object is moving vertically.

**How are projectiles related to vectors?**

When someone fires a projectile, its initial velocity can be represented by a vector where the magnitude is the overall speed and the angle is the direction of the projectile. After its launch, a projectile’s motion can be divided into vertical and horizontal components.

**What is the formula for projectiles?**

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.

### How is VX and VY calculated?

- Horizontal velocity component: Vx = V * cos(α)
- Vertical velocity component: Vy = V * sin(α)
- Time of flight: t = [Vy + √(Vy² + 2 * g * h)] / g.
- Range of the projectile: R = Vx * [Vy + √(Vy² + 2 * g * h)] / g.
- Maximum height: hmax = h + Vy² / (2 * g)

### How do you get V from VX and VY?

- To get vx,y you can just take the time derivative of x(t) and y(t).
- The idea is that v0 will not change through the whole motion, what will change is the ratio between vx and vy but it should always be equal to the desired speed v = sqrt(vx^2 + vy^2) should always be equal to the set velocity.

**What is the sum of adding two or more vectors?**

The sum of two or more vectors is called the resultant. The resultant of two vectors can be found using either the parallelogram method or the triangle method .

**How do you find the position vector in projectile motion?**

26.3. 1 Use the trace key to approximate when the projectile reaches its highest point and estimate the position vector at the highest point….Select Degree in the Mode menu.

- Set X1T = 180*T*cos(20).
- Set Y1T = 180*T*sin(20) – (1/2)*32*T^2.
- Unselect X2T and Y2T.
- Unselect X3T and Y3T.

#### What are the 3 types of projectile motion?

Types of Projectile Motion :

- Types of Projectile Motion :
- (1) Oblique projectile motion.
- (2) Horizontal projectile motion.
- (3) Projectile motion on an inclined plane.

#### How are VX and VY different?

Vx is the speed where you have the most excess force (thrust), and Vy is the speed where you have the most excess power (horsepower).

**How do you get VX?**

A person’s clothing can release VX after contact with VX vapor, which can lead to exposure of other people through contaminated clothing. Because VX breaks down slowly in the body, repeated exposures to VX and/or other nerve agents can build up in the body (have a cumulative effect).

**What is the formula for resultant of two vectors?**

R = A + B.

## Can you add two vectors representing?

No, we cannot add two vectors representing physical quantities of different dimensions. However, we can multiply two vectors representing physical quantities with different dimensions.

## How do you find the velocity vector?

Let r(t) be a differentiable vector valued function representing the position vector of a particle at time t. Then the velocity vector is the derivative of the position vector. v(t)=r′(t)=x′(t)ˆi+y′(t)ˆj+z′(t)ˆk.

**How do you find VX and VY in projectile motion?**

Projectile motion equations

- Horizontal velocity component: Vx = V * cos(α)
- Vertical velocity component: Vy = V * sin(α)
- Time of flight: t = 2 * Vy / g.
- Range of the projectile: R = 2 * Vx * Vy / g.
- Maximum height: hmax = Vy² / (2 * g)

**What is the equation of trajectory in projectile motion?**

The equation of Trajectory: \\(Equation\\,of\\,Trajectory = x\an \\Theta -\\frac{gx^2}{2u^2cos^{2}\\Theta }\\) This is the Equation of Trajectory in projectile motion, and it proves that the projectile motion is always parabolic in nature.

### What is the Y component of the original velocity of a projectile?

(The v oy is the y-component of the original velocity.) A non-horizontally launched projectile (or angled-launched projectile) is a projectile which is launched at an angle to the horizontal. Such a projectile has both a horizontal and vertical component to its original velocity.

### What is a projectile in physics?

A projectile is an object which upon which the only force of influence is the force of gravity. As a projectile moves through the air, its trajectory is effected by the force of gravity; air resistance is assumed to have a negligible effect upon the motion.

**How do you solve projectile motion problems?**

The basic approach to solving projectile problems involves reading the problem carefully and visualizing the physical situation. A well-constructed diagram is often a useful means of visualizing the situation. Then list and organize all known and unknown information in terms of the symbols used in the projectile motion equations.
