Qualitatively: It depends on the slope angle Physics 102 Falling Objects Slide 1 Department of Physics, The University of Arizona It depends on the properties of the ball It depends on the Earth’s gravity We’ll learn the details later in this course. Meanwhile, let’s study a special case: Pure vertical motion, or free fall . Concluding remark...
