Any object near the surface of the earth and not constrained experiences a
downward vertical acceleration of 9.8 meters (32.2 feet) per second2 because
of the mutual force of gravitational attraction between it and the earth.
The acceleration changes direction at the highest point of the ball's motion. At that point, the ball momentarily stops moving upward and starts moving downward, causing the acceleration to change from upward to downward.
Never. The acceleration is constant, from the time the ball leaves your hand
until it hits the ground. Its value is 9.8 meters /sec2 downward. . . the acceleration
of gravity.
It's the velocity of the ball that changes directions, right at the top of the arc,
where the ball stops going up and starts going down.
=======================================================
What is said above is entirely correct. Here's a good way to remember this:
When you throw a ball up in the air, you have given the ball an initial velocity in the positive (up) direction. From the second the ball leaves your hand, the acceleration due to gravity constantly pulls the ball downward, slowing the upward velocity by 9.8 m/s every second. Thus, as the ball is travelling upward, the distance traveled per second continually gets shorter since the ball is slowing down. Once acceleration has slowed the ball down enough, it will stop travelling upward and start to fall back to earth. It is at this point that velocity has changed direction, as a result of the downward acceleration overpowering the upward motion of the ball.
Vertical force does. It's as simple as that.
The vertical acceleration is caused by gravity.
zero -9.8 m/s2
The ball thrown straight down from a bridge will experience an acceleration due to gravity. On Earth, this acceleration is approximately 9.81 m/s^2 and acts in the downward direction. The acceleration will cause the ball to increase in speed as it falls towards the ground.
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
The acceleration of a ball at the top of its trajectory when thrown straight upward is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 downward. At the top of its trajectory, the ball momentarily comes to a stop before reversing direction and accelerating downward.
Its acceleration points straight down at all times after it's released.
No, the acceleration is not the same for an object that is dropped and an object that is thrown. When an object is dropped, it experiences a constant acceleration due to gravity. When an object is thrown, its acceleration can vary depending on factors such as the initial velocity and direction.

At the top of its trajectory, the acceleration of the stone is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 directed downward. This is because at the highest point, the stone momentarily comes to a stop before it starts falling back down.
9.8 m/s (2) Squared
When a ball is thrown, the force of gravity affects its trajectory, causing it to follow a curved path instead of a straight line. Additionally, air resistance and spin on the ball can also contribute to the curve as it travels through the air. This combination of factors leads to the typical arc path that we observe when a ball is thrown.
Yes, Earth exerts a downward force on the ball due to gravity, causing it to fall back to the ground. This creates an unbalanced force on the ball when it is thrown upward, with gravity acting to pull it back down.
The vertical component of the acceleration vector is the acceleration due to gravity (9.81 m/s^2 downward). The horizontal component of the acceleration vector is zero since there is no acceleration acting in the horizontal direction (assuming no external forces).
Under ideal conditions, when an object is thrown vertically upward, the acceleration due to gravity will cause the object to decelerate until it reaches its highest point. At that point, the object will momentarily have an acceleration of -9.81 m/sĀ² (assuming downward is negative), before accelerating downward due to gravity as it falls back towards the ground.
To find the initial velocity, we first calculate the time it takes for the ball to reach the highest point, which is half of the total time taken (t/2 = 6/2 = 3 seconds). Then, we use the equation v = gt, where v is the initial velocity, g is the acceleration due to gravity (9.81 m/s^2), and t is the time taken to reach the highest point (3 seconds). So, v = 9.81 m/s^2 * 3 s = 29.43 m/s.
No, the acceleration at the highest point is never 0.
