Honors Physics Free Fall Blog
For the following blog, please discuss at least three sources of error in the ball drop experiment performed today. Also, comment on whether or not you think someone else's sources of error were correct or relevant. Finally, answer the following question below in with your sources of error.
An object falls freely from height h. It is released at time zero and strikes the ground at time t. a) When the object is released from height 0.5h, is the time to fall less than, greater than, or equal to time 0.5h? When the time to fall is 0.5t, is the distance of the drop less than, equal to, or greater than height 0.5h? Explain your answers.
