Question

Which factor is most important in projectile motion?

Answer 1

Any particle/ body thrown at an angle to the horizontal is called a projectile; its motion is called projectile motion.
The path is a parabola normally
Examples are 1. Hopping of a frog in nature
2. putting shot/ javelin throw

Complete answer:
A projectile is an object in which the only force acting on an object is gravity. There are some examples of projectiles. When An object is dropped from its rest position it is known as a projectile which ensures that the influence of air resistance is negligible. When An object is thrown upward which is also a projectile it provides that the influence of air resistance is negligible.
And when an object which is thrown upward at an angle to the horizontal is also a projectile it also provided that the influence of air resistance is negligible.
At the maximum height, the vertical velocity is zero. The horizontal velocity is constant and it does not have any acceleration. Vertical velocity has a uniform acceleration.
**The three most important factors in projectile motion are:
- The projection angle
- The magnitude of projectile velocity
- The height of the projection

Note:
A body that is thrown then if gravity is the only force acting on the body, such a body is said to be in projectile motion.
The path taken by a body in projectile motion is like a parabola
Generally, the Motion of the body has two aspects: Vertical aspects and Horizontal aspects.
