In other words, given equal size in terms of diameter, the ball with the greater mass will roll farther. How does projectile motion relate to linear motion? That is basically the reason that mass does not affect the results of analysis of a projectile. Recall the mechanisms you used and any problems that may have come up. So mass resists a chang. This is because a force is just an interaction that tries to change the momentum of an object, and the momentum depends on the mass; the larger the mass, the larger the momentum, and the more force you need to change it. The heavy object will feel small changes to its speed (its acceleration is close to zero), while the light object will slow down a lot (its acceleration is a large negative number).

Direct link to Natalie Semerky's post 45 degrees optimizes the , Posted 4 years ago. The simplest type of projectile motion is a ball being projected horizontally from an elevated position. When writing equations of motion for a dropped object, mass is in the equations in 2 places and they cancel out. How the Mass of an Object Affects Its Motion | Sciencing y Why does mass not affect projectile motion? 1 This demonstration could be extended by using digital photography. How do astronauts brush their teeth in space? 0 Each triangle's hypotenuse is a thick purple arrow, while its two legs are dashed purple lines. This kind of problem gets to the heart of what engineering is all about. y When an object is dropped from a tower, mass does not affect final velocity or time. The angle from which an arrow is shot also determines the arc traversed by the arrow and how far it will go. This book uses the v [BL][OL][AL] Talk about the sample problem. v x It is the observed effect of momentum and energy as they interact to conserve their constant values, while allowing bodies of mass to move in space.
