# Why if a ball is released horizontally and then the same ball is released vertically they hit the ground at the same time?

## Why if a ball is released horizontally and then the same ball is released vertically they hit the ground at the same time?

Both of the balls are falling vertically under the influence of gravity. They both fall from the same height. Therefore, they will hit the ground at the same time. The fact that one is moving horizontally is irrelevant – remember that the x and y motions are completely independent !!

## What is the motion of a ball thrown horizontally?

Projectile motion: The interesting thing about the projectile motion is that its horizontal and vertical motions can be separated from one another. The horizontal motion is uniform motion with constant speed, while the vertical motion is a uniformly accelerated motion.

## What is the path taken by a ball launched horizontally?

An object launched horizontally at a height H travels a range v0√2Hg during a time of flight T=√2Hg. 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.

## What is a projectile launched horizontally with?

A projectile is launched with an initial horizontal velocity from an elevated position and follows a parabolic path to the ground. Predictable unknowns include the initial speed of the projectile, the initial height of the projectile, the time of flight, and the horizontal distance of the projectile.

## What is the formula for horizontal motion?

(b) The equation that describes the horizontal motion is x=x0+vxt. x = x 0 + v x t . With x0=0, x 0 = 0 , this equation becomes x=vxt.

## When one ball is thrown horizontally and another ball is dropped simultaneously from the same height?

The time required for initially horizontal projectile motion to occur is the same as the time required for the object to fall to its final height. Thus, a ball thrown horizontally will reach the ground at the same time as a ball dropped from the same height.

## What are 2 examples of horizontal motion?

Examples of Horizontal Motion A bullet fired from a gun. Throwing a ball or a cannonball. Movement of a billiard ball on the billiard table. The motion of the planet Earth around the Sun.

## What is the velocity of a ball thrown horizontally?

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 happens if we drop a ball in horizontal direction than its motion?

The horizontal motion of the ball is independent of its vertical motion because the force of gravitation is acting perpendicular to the horizontal direction.

## Why is G negative in projectile motion?

This is because though the acceleration due to gravity always acts downwards, it is in a direction opposite to the motion of the projectile when the projectile is moving upwards, which means that it becomes \$-g\$ with respect to the projectile trajectory.

## Who discovered projectile motion?

Galileo was the first to properly describe projectile motion as consisting of separable horizontal and vertical components. After close observation, Galileo determined that the only vertical force acting on a projectile was gravity (9.81 meters/second^2).

## What are the three types of projectile motion?

There are three types of projectile motions- Oblique Projectile Motion, Horizontal Projectile Motion, and Projectile Motion on an Inclined Plane.

## Will an object thrown horizontally and an object dropped vertically hit the ground at the same time?

Its y-axis velocity, the speed at which it moves downwards, is determined purely by gravity, just as in the case of the dropped ball, as none of the throwing force is directed downwards. Both the balls have the same velocity along the y-axis and therefore should reach the ground at the same time.

## Why do balls reach the ground at the same time?

The force of gravity acting on the two balls is the same, causing them to fall at the same velocity and land at the same time.
