Projectile motion calculator5/22/2023 ![]() As you proceed through this part of Lesson 2, pay careful attention to how a conceptual understanding of projectiles translates into a numerical understanding.Ĭonsider again the cannonball launched by a cannon from the top of a very high cliff. ![]() You will learn how the numerical values of the x- and y-components of the velocity and displacement change with time (or remain constant). In this portion of Lesson 2 you will learn how to describe the motion of projectiles numerically. The horizontal motion of a projectile is independent of its vertical motion.The vertical velocity of a projectile changes by 9.8 m/s each second,.There is a vertical acceleration caused by gravity its value is 9.8 m/s/s, down,.The horizontal velocity of a projectile is constant (a never changing in value),.There are no horizontal forces acting upon projectiles and thus no horizontal acceleration,.Projectiles travel with a parabolic trajectory due to the influence of gravity,.A projectile is any object upon which the only force is gravity,.So far in Lesson 2 you have learned the following conceptual notions about projectiles.
