Uniform acceleration is a type of motion where an object&#8217;s velocity changes by an equal amount in every equal time period. In the case of a freely falling object, gravity causes acceleration, which is uniform because gravity is almost uniform in the atmosphere.\n\n<\/p>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>22.
