An object falls freely from rest in a vacuum. The graph shows the variation with the time t of the velocity v of the object.WebAug 28, 2024 · The t -distribution, also known as Student’s t -distribution, is a way of describing data that follow a bell curve when plotted on a graph, with the greatest number of observations close to the mean and fewer observations in the tails. It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown.
