What is the acceleration at highest pointn when ball is thrown straight up?
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.
In throwing a ball upward discuss the velocity and acceleration when the ball returns to the thrower's hand?
A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.
Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
When A ball is thrown straight up from the ground. What way does its acceleration point at the top?
Its acceleration points straight down at all times after it's released.

WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
Why is the ball deccelerating on an inclined plane?
The acceleration due to gravity remains constant, regardless of incline. The fact that it is on an incline does not change the fact that it will remain constant, it will only change the component of that acceleration being applied to the ball.

What is the speed and acceleration of a ball rolling down a hill?
The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration.
What are the different forces acting on the ball while it’s in the air?
Gravity, force, and acceleration.

If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?
Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.
When A ball is thrown straight up from the ground. What way does its acceleration point at the top?
Its acceleration points straight down at all times after it's released.
Why throwing a ball always put down in curve not in straight?
-- The only horizontal force on a thrown ball is the force of air resistance, so the horizontal acceleration is very small, and the horizontal speed stays almost constant. -- The vertical force on a thrown ball is the force of gravity, so the ball accelerates straight down at the acceleration of gravity. -- The result of unequal horizontal and vertical components of acceleration is a curved path.
How do you find the acceleration of a ball that is being thrown as a projectile as it is leaving your hand... Just the acceleration as it leaves the hand?
After, and at the exact moment, the ball leaves the hand it is only accelerated by gravity if you disregard air resistance.
