# Why does a dropped object have the same vertical velocity as an object launched horizontally?

## Why does a dropped object have the same vertical velocity as an object launched horizontally?

What it shows: The horizontal and vertical motions of a projectile are independent of each other. So two objects falling under the influence of gravity from the same height will reach the ground simultaneously, regardless of their horizontal velocities.

## Is a motorcycle taking off on a ramp projectile or not?

Projectile Motion: When a motorcycle leaves a ramp, it follows a parabolic path caused by projectile motion.

## What is the vertical acceleration of a projectile due to gravity?

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 is the final velocity of a motorcycle?

Final velocity of motorcycle is √3 times initial velocity.

## Why is 45 degrees the best launch angle?

At 45 degrees it is the best combination of time of flight and horizontal speed. At lower angles you have a lot less time of flight but only a very little increase in horizontal speed so the distance it moves in that lower time is less.

## What is true of the vertical velocity of a dropped or a horizontally launched object?

Remember: What happens in the vertical direction does NOT affect the horizontal direction, and vice versa. An object’s horizontal position, velocity, or acceleration does not affect its vertical position, velocity, or acceleration. These motions can only be related by the time variable ‍ .

## Are motorcycle and car moving on a horizontal road with the same velocity if they are brought to rest by the application of brakes?

Therefore, both will stop at the same distance.

## Is an airplane taking off an example of projectile motion?

When a plane takes off, it does not take off in a parabolic trajectory. As a result, there is no projectile motion.

## Why don t motorcycles fall while moving?

A bike remains upright when it is steered so that the ground reaction forces exactly balance all the other internal and external forces it experiences, such as gravitational if leaning, inertial or centrifugal if in a turn, gyroscopic if being steered, and aerodynamic if in a crosswind.

## What causes constant velocity?

An object has constant velocity when both the magnitude and direction of the rate at which such an object is changing its position remain constant. In other words, for an object to have constant velocity its movement has to not change directions over time and the object must have constant speed as well.

## 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.

## Why is 45 degrees the maximum range?

At angles greater than 45 degrees, the vertical component of the object’s velocity becomes more significant, causing it to spend more time in the air. However, the drag force acting opposite to the direction of motion slows the object down more rapidly, reducing its overall range.

## When an object falls vertically down does its velocity remain the same?

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth (see figure 1).

## How does vertical velocity change when an object is dropped?

(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.

## Why is the velocity in the horizontal direction the same throughout the fall what is the force acting on the object?

Horizontal velocity is constant The projectile’s horizontal speed is constant throughout the entire trajectory (see figure 2 below) because gravity only acts downwards in the vertical direction.

## Why does a ball launched horizontally and another dropped from the same height at the same time hit the ground simultaneously?

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 !!
