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 factor is most important in projectile motion?

There are 3 factors that are most important in projectile motion:

• The projection angle.
• The magnitude of projectile velocity.
• The height of the projection.

## What are the factors that 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 are the factors affecting motion?

There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.

## How many motion does a projectile have?

The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical.

## What is the importance of projectile motion in sports?

DIVING. Inertia plays an important role in projectile motion, because it explains why an object keeps moving without any source of propulsion. There is also a force at play: gravity. Gravity explains why the soccer ball in the above example returns to Earth, rather than moving continuously through the air.

## What is the difference between projectile motion and trajectory?

The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning, after which the only influence on the trajectory is that of gravity.

## Why is 45 degrees the optimal angle for projectiles?

The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

## What is the optimum angle?

Introduction. One of the best known ‘results’ of the science of mechanics is that the optimum projection angle for achieving maximum horizontal range is 45°. However, it is also well known that actual performers in projectile-related sports seldom use an angle of 45°.

## How do you calculate drop by height?

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.
