 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following affects the launched of the projectile motion?
 A angle B Force C Gravity D object
Explanation:

Detailed explanation-1: -The most important factors affecting projectile motion are: The angle of the launch: The angle at which the object is thrown determines how high (vertically) or how far (horizontally) the object will reach. Initial speed: Greater the initial speed of launch, the higher and farther will the object reach.

Detailed explanation-2: -Factors affecting the flight path of a Projectile are: Gravity. Air Resistance. Speed of Release. Angle of Release.

Detailed explanation-3: -A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it-the force of gravity.

Detailed explanation-4: -13 Answers 1. Gravity, air resistance, speed of release, angle of release, height of release 2. It decreases the height the projectile can attain 3. Air resistance acts on the horizontal component of a projectiles path, meaning it affects the distance it can travel horizontally.

Detailed explanation-5: -There must be a horizontal force to cause a horizontal acceleration. (And we know that there is only a vertical force acting upon projectiles.) The vertical force acts perpendicular to the horizontal motion and will not affect it since perpendicular components of motion are independent of each other.
