How did Galileo explain projectile motion?

Through these experiments, Galileo established that the motion of a projectile is a combination of constant horizontal velocity and vertical motion, in which the projectile accelerates at a rate of 9.8 m s–2. The points i, f, h give the position of the projectile after equal time intervals.

Who first described projectile motion?

Galileo was the first person who ever accurately described projectile motion. He was the one who first broke down motion into it’s separate horizontal and vertical components (Web 1). Galileo even took this idea further with his realization that there was more than one force at work upon the projectile.

What is horizontal motion of Galileo?

Galileo believed that a projectile is a combination of uniform motion in the horizontal direction and uniformly accelerated motion in the vertical direction. If it is not impeded, it will continue to move even without an applied force.

What are the characteristics of a projectile motion?

Characteristics of a Projectile’s Trajectory. a projectile is an object upon which the only force acting is gravity. Many projectiles not only undergo a vertical motion, but also undergo a horizontal motion. That is, as they move upward or downward they are also moving horizontally.

What motion does a projectile take?

Projectile motion is a form of motion where an object moves in a parabolic path . The path followed by the object is called its trajectory. Projectile motion occurs when a force is applied at the beginning of the trajectory for the launch (after this the projectile is subject only to the gravity).

What is projectile motion theory?

Theory Projectile motion is an example of motion with con- stant acceleration when air resistance is ignored. An object becomes a projectile at the very instant it is re- leased (fired, kicked) and is influenced only by gravity.

How does velocity change in projectile motion?

In case of projectile motion the vertical component of particle’s velocity changes continuously because of the force acting in vertical direction which is its own weight (#mg#). But in the horizontal direction as there is no force acting on the. object ; its horizontal velocity remains constant.
