If the linear velocity of the mass centre changes and the angular velocity changes then there will be a unique point at which these two cancel, leaving no change in linear velocity.Clara Chung said:
I tried to express change in angular velocity, which isharuspex said:
Where does the 1.3 come from? What axis are you using here?Clara Chung said:
You cannot add a velocity to an angular velocity.Clara Chung said:
I am using the rotational pivot. Am I right?haruspex said:
Does that fit with the way k0 is defined?Clara Chung said:
Thank you so much. I solved it by using the centre of mass frame^^haruspex said:
Very good.Clara Chung said:
The centre of percussion of a baseball bat is the point on the bat where the impact of a ball creates minimal vibration and maximum energy transfer.
The centre of percussion is determined by finding the point on the bat where the ball can be struck without causing any noticeable vibration or discomfort to the hands. This is typically done through experimentation and trial and error.
The centre of percussion is important for a baseball player as it allows for maximum energy transfer from the bat to the ball. This can result in a more powerful hit and increase the chances of getting a solid hit.
Yes, the centre of percussion can change for a baseball bat depending on factors such as the material, shape, and weight of the bat. It can also vary for different players with different swing styles and strengths.
It is not necessary to find the centre of percussion for every baseball bat, but it can be beneficial for players to do so in order to determine the optimal point for hitting the ball with maximum power and efficiency. It can also help in selecting the right bat for a player's swing style.
