# Readers ask: When A Baseball Is Thrown Straight Upward What Is Its Acceleration At Its Greatest Height?

## When a ball is thrown straight up the acceleration at its highest point?

When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the balls motion. Its acceleration is -9.8 m/s^2 at the very top.

## What is the acceleration of an object thrown vertically upward at the maximum height?

Its value is generally taken as 9.8 m/s^2. See here how acceleration due to gravity varies with height and depth wrt the surface of the earth.

## What is the acceleration of a baseball that is thrown straight up?

The baseball is thrown straight up, so the acceleration due to gravity is −9.8 ms2.

## What is the acceleration of a rock thrown straight upward on the way up at the top of its flight on the way down?

Answer: The acceleration of a rock thrown straight upward on the way up, at the top of its flight and on the way down is called gravity, and it’s denoted by the letter g.

## What is its acceleration at the highest?

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

## At what point is the acceleration of the ball zero?

After 1.0 second, the ball has zero velocity because it’s reached the top of its trajectory, just at the point where it’s about to fall back down again. So the acceleration has actually slowed down the ball because it was going in the direction opposite the velocity.

## What is the maximum height when the final velocity is zero?

Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.

## What is the acceleration of the ball after 1 second?

After 1 second, the velocity is 4.5+1.5=6 m/s. After 3 seconds, the velocity is 4.5+3×1.5=9 m/s.

## What it is acceleration just before it hits the ground?

So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.

## Is acceleration always negative when slowing down?

When a car is slowing down, the acceleration and velocity are in opposite directions. The acceleration is negative. A change in velocity is either a change in an object’s speed or its direction. When a moving object changes direction, its velocity changes and it is accelerating.

## What is the vertical acceleration of the ball after 1 second after a baseball is thrown horizontally?

So after one second, the acceleration of the ball is 9.8 m/s² and its velocity is 9.8 m/s. When you throw the ball upward, that acceleration is still 9.8 m/s².

## What is the acceleration of free falling object?

With algebra we can solve for the acceleration of a free falling object. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.

## What is the acceleration of a rock thrown upward on the way up?

Answer: The acceleration of a rock thrown straight upward on the way up, at the top of its flight and on the way down is called gravity, and it’s denoted by the letter g.

## How does the acceleration of a stone thrown upward compare to the one thrown downward?

The force acting on the object is equal to the force of gravity when an object is thrown upward or downward. Hence, both the objects will have same acceleration when they have dropped from same height.

## What is the acceleration of a rock thrown on the way down?

Notice that when the rock is at its highest point (at 1.5 s), its velocity is zero, but its acceleration is still -9.80 m/s2. Its acceleration is -9.80 m/s2 for the whole trip—while it is moving up and while it is moving down.
