# what is the acceleration of a rock thrown straight upward

Whatever the velocity direction or the magnitude, the acceleration on the stone is still constant. It is called acceleration due to gravity having a value around 9.80 m/s2 9.80 m / s 2 on the surface of the Earth.

## What is the acceleration of an object thrown upward?

When you throw a ball up in the air, its speed decreases, until it momentarily stops at the very top of the ball’s motion. Its acceleration is −9.8 ms−2 at the very top since the body is moving upward against the gravity. In other words, the acceleration due to gravity g=9.8 ms−2↓.

## What is the acceleration of a rock that is tossed straight up at the moment it reaches the top of its trajectory?

What will be the acceleration of a rock thrown straight upward at the moment it reaches the tippity-top of its trajectory? The acceleration is zero because when the rock reaches the tippity top of its trajectory the velocity is zero thus the acceleration is also zero.

## What is the acceleration of a rock at the top?

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.

## Is the acceleration of an object thrown upward positive or negative?

If an object is thrown in upward direction, then the gravitational acceleration is positive.

## What is the acceleration of an object moving up?

In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

## Does acceleration change when an object is thrown up?

Analyzing motion for objects in freefall Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.

## What is the acceleration of an object thrown downward?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name.

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

When a rock thrown straight upward gets to the exact top of its path, the magnitude of its a. velocity is zero and its acceleration is zero.

## What is the acceleration of a rock at the top of its trajectory when thrown straight upward is your answer consistent with Newton’s second law?

So, the acceleration of a ball at the top of its trajectory when thrown straight upward is − 9.81 m/s 2 . Conclusion: Therefore, the acceleration of a ball at the top of its trajectory when thrown straight upward is − 9.81 m/s 2 . Have a homework question?

## What is the acceleration on the way up if the stone is thrown straight upward?

On the way up, the speed of the ball slows down until at the very top, it has a velocity of zero. The ball’s acceleration is the same throughout the throw (It is 9.8 m/s2 toward the earth). The direction of the ball’s motion is upward, and doesn’t change. The speed of the ball will decrease as it goes higher.

## What is the acceleration of an object that is thrown upwards when it reaches the highest point?

Its acceleration is −9.8 ms−2 at the very top since the body is moving upward against the gravity. In other words, the acceleration due to gravity g=9.8 ms−2↓.

## What is the acceleration of a rock at the top of its flight?

When a rock thrown straight upward gets to the exact top of its path, the magnitude of its a. velocity is zero and its acceleration is zero.

## What is the acceleration of an object at the top?

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

## What is the acceleration of a rock at the top of its trajectory when it is thrown straight upward?

Conclusion: Therefore, the acceleration of a ball at the top of its trajectory when thrown straight upward is −9.81 m/s2.
