I chose Answer 5 but the given answer was 1. Am I correct or what was the mistake?
The acceleration towards the Earth ip positive so when we throw the ball in opposite direction acceleration will be negative and this causes the initial velocity to decrease and become zero at some height after the U-turn object travels towards Earth which causes positive acceleration hence the velocity increases.Orodruin said:What is your reasoning for choosing 5?
Why? Does the direction of acceleration depend on the velocity?Manasan3010 said:The acceleration towards the Earth ip positive so when we throw the ball in opposite direction acceleration will be negative
Have a look at this linkOrodruin said:Why? Does the direction of acceleration depend on the velocity?
Note that acceleration is related to the change in velocity, not to the change in speed.
That is not how this forum works. You have been given several hints as to how to think about this problem. It is better for your long time learning to consider those hints and their implications. If you are still confused after that, you need to specify what confuses you and why. You will not be handed the answer on a platter because that is not a good way of learning.Manasan3010 said:Have a look at this link
Please explain me the answer I am so confused :(
In graphs of a thrown ball, assume that time starts when the ball leaves the hand. So would the acceleration of the throwing motion be part of the graph?Manasan3010 said:The acceleration towards the Earth ip positive so when we throw the ball in opposite direction acceleration will be negative and this causes the initial velocity to decrease and become zero at some height after the U-turn object travels towards Earth which causes positive acceleration hence the velocity increases.
I think the instantaneous jump to a positive acceleration is caused at the point where object starts to return to the Earth from air.
An acceleration graph is a visual representation of an object's acceleration over time. It shows how the velocity of an object changes over time, and can also indicate the direction of the acceleration.
An acceleration graph shows the rate at which an object's velocity is changing, while a velocity graph shows the actual velocity of the object at a given time.
The slope of an acceleration graph represents the object's acceleration. A steeper slope indicates a higher acceleration, while a flatter slope indicates a lower acceleration.
Acceleration can be calculated by finding the slope of the acceleration graph. This can be done by dividing the change in velocity by the change in time.
By analyzing the shape and slope of an acceleration graph, we can predict how an object will move in the future. A positive slope indicates a speeding up motion, while a negative slope indicates a slowing down motion. A flat line indicates a constant velocity.
