What else can I help you with?
When a ball is thrown upwards is there any change in its acceleration all throughout its motion?
Yes, the acceleration of the ball will change. Initially, the acceleration is downward (due to gravity) while the ball is speeding up. As it reaches its peak height, the acceleration becomes zero. On the way back down, the acceleration is again downward and the ball speeds up due to gravity.
Can velocity of an object be in different direction than the acceleration?
Yes. For example, a ball thrown vertically in the air has a positive velocity (upwards) but a negative acceleration due to gravity (downwards at ~9.81 m/s^2), until it begins to move downwards.
Is a ball rolling an example of acceleration?
Not necessarily. If it's rolling in a straight line on a smooth and level floor, then the acceleration is as good as zero. But if the ball is rolling up a hill, or down a hill, or around the groove in a roulette wheel, or through grass and slowing down, then there's substantial acceleration.
What are examples of acceleration in science?
Examples of acceleration in science include a car speeding up or slowing down, a ball accelerating downwards due to gravity, and a rocket launching into space. These situations involve changes in velocity over time.
Three things that can be acceleration?
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.

When is velocity antiparallel to acceleration?
Velocity is antiparallel to acceleration when an object is moving in the opposite direction of the acceleration. This means that the object is slowing down due to the acceleration acting in the opposite direction to the object's motion.
Is it possible for a body to have its velocity and acceleration pointing in opposite directions?
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.
What is the acceleration of the ball after 1 seconds?
The acceleration of the ball is about 9.8 m/s^2, which is the acceleration due to gravity.
What is easier to roll a bolling ball on?
A flat, smooth surface would be ideal for rolling a bowling ball successfully. Usually, wooden floors that were waxed are used in bowling lanes. This gives the bowling ball less friction, thus, giving it more acceleration and less slowing down.
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes, it is possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration. This occurs when an object is moving in the positive direction but slowing down due to a decrease in its speed.
What are the examples of accelaration?

What type of motion is exhibited by a ball thrown up uniform or non uniform motion why?
If by motion you mean velocity it is non uniform, because the velocity is changing due the acceleration of gravity slowing it down to zero. Then at the maximum height motion is reversed and it accelerates downward back to its original speed but in the opposite direction.
