## What are the major components of a 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 are some applications of projectile motion?

The applications of projectile motion in physics and engineering are numerous. Some examples include meteors as they enter Earth’s atmosphere, fireworks, and the motion of any ball in sports. Such objects are called projectiles and their path is called a trajectory.

## What are the importance of knowing projectile motion?

By studying the motion of things traveling in the air, also known as projectiles, we can figure out just how fast the food needs to be launched in order for it to get to them.

## Why do we need to know projectile motion?

The projectile motion emphasizes one important aspect of constant acceleration that even constant acceleration, which is essentially unidirectional, is capable to produce two dimensional motion. The basic reason is that force and initial velocity of the object are not along the same direction.

## What factors affect projectile motion?

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 is horizontal motion?

Horizontal motion is defined as a projectile motion in a horizontal plane depending upon the force acting on it. For a short distance, the vertical and horizontal components of a projectile are perpendicular and independent of each other.

## What is vertical and horizontal motion?

There is a major difference between the vertical and the horizontal motion of a projectile. This is that the vertical motion is changing, but the horizontal motion is constant (supposing no friction force from air resistance). No friction means that there is no force in the opposing direction.

## What is its horizontal speed?

The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.

## What is vertical motion?

Vertical motion is referred as the movement of the object against the gravitational pull. It is the motion that is perpendicular to the straight or flat surface. It can also be a straight upward and downward motion but the perfect vertical motion does not usually pursue a straight line path.

## What is vertical motion formula?

1. The vertical motion model is h=-16t(squared)+vt+s. T represents the time (in seconds) that something has been airborne, and V is the initial velocity (in feet per second). S represents the initial height (in feet).

## What is the example of vertical motion?

Examples: A ball is thrown upwards from a balcony with a speed of 3 m/s, 8 m above the ground. Find the time taken for the ball to hit the ground and the speed at which it hits the ground.

## What direction is vertical motion?

Typically, we define the positive vertical direction as upwards, and the positive horizontal direction is usually the direction of the object’s motion.

## Why is horizontal and vertical motion independent?

The horizontal and vertical components of two-dimensional motion are independent of each other. Any motion in the horizontal direction does not affect motion in the vertical direction, and vice versa. This is true in a simple scenario like that of walking in one direction first, followed by another.

## What is the path of a projectile motion?

Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory.

## What is vertical acceleration?

Gravity causes a vertical acceleration. The ball will drop vertically below its otherwise straight-line, inertial path. Gravity is the downward force upon a projectile that influences its vertical motion and causes the parabolic trajectory that is characteristic of projectiles.

## Why is vertical acceleration negative?

Acceleration tells you the rate at which the velocity is changing. Now the ball is under the influence of gravity, which, on the surface of the Earth, causes all free-falling objects to undergo a vertical acceleration of –9.8 m/s2. This acceleration is negative because its direction is vertically downward.

## What is the acceleration at maximum height?

At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.

## Which component of acceleration of a projectile is zero?

horizontal component

## What are the 3 ways of acceleration?

There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
