# Often asked: When No Air Resistance Acts On A Fast-moving Baseball?

## How does no air resistance affect projectile motion?

As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile. The effect of air resistance is very small, but needs to be considered if you want to increase the horizontal component of a projectile.

## When no air resistance acts on a projectile the horizontal component of the velocity?

In the absence of air resistance there are no forces or components of forces that act horizontally. A velocity vector can only change if there is acceleration (acceleration is the rate of change of velocity).

## What is the significance of a projectile that travels at a rate of 8 km SEC?

8km/s is the orbital speed for low earth orbit; this means that the projectile is moving fast enough, that for every meter it falls toward the center of the earth, it moves “forward” fast enough that the curvature of the earth slips away by 1 meterso that the distance between the projectile and surface of the earth

## Is it ever possible for the minimum speed of a projectile to equal its initial speed?

A projectile have a minimum speed at the highest point of its trajectory. This is because horizontal speed of the projectile remains constant. Since the only force exerted on the projectile is gravity, which is 9.8 ms2 acting downwards and has no effects on the horizontal velocity.

## What if there was no air resistance?

If there is no air resistance, after you let go of an object the only force on it is the gravitational force. The gravitational force is proportional to the mass of the object. The acceleration of an object is proportional to the net force on the object and inversely proportional to the mass of the object.

## What does it mean when there is no air resistance?

Air Resistance. When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum. A rock and a feather are released from rest from the same height with air resistance on.

## What is the horizontal acceleration of a projectile neglect air resistance?

Neglecting air resistance, what is its vertical acceleration? Its horizontal acceleration? Its vertical acceleration is g because the force of gravity is downward. Its horizontal acceleration is zero because no horizontal force acts on it.

## What force acts in the Y direction that causes an object to travel in a parabolic arc?

In conclusion, projectiles travel with a parabolic trajectory due to the fact that the downward force of gravity accelerates them downward from their otherwise straight-line, gravity-free trajectory.

## Does air resistance affect vertical velocity?

Velocity and air resistance are proportional. Mathematically, sometimes it is proportional to the square of the velocity. Nonetheless, as velocity increases, so does air resistance.

## At what angle should a slingshot be aimed for maximum height?

at what angle should a slingshot be oriented for maximum altitude? for maximum horizontal range? straight up; 45 degrees.

## When the golf ball reaches the maximum height does it momentarily stop or not?

Velocity in the Y direction at the halfway point, or midpoint (Vy, mid) is zero. This is because when the ball reaches its highest point, it stops momentarily before reaching the ground.

## At what angle of projectile is the horizontal range minimum?

Horizontal range, like time of flight and maximum height, is greater for greater projection speed. For projection above ground surface, the range of the angle of projection with respect to horizontal direction, θ, is 0° ≤ θ ≤ 90° and the corresponding range of 2θ is 0° ≤ 2θ ≤ 180°.

## What is acceleration at maximum height?

At a projectile’s highest point, its acceleration is zero.

## At what point projectile has maximum and minimum speed?

The speed is maximum at the highest point. At the highest point of the trajectory of a projectile, its speed is minimum. This is because the horizontal speed of the projectile remains constant.

## What do you call the trajectory of a projectile in free fall?

The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which the only interference is from gravity. One of the key components of projectile motion and the trajectory that it follows is the initial launch angle.
