We know that projectile motion is a type of two-dimensional motion or motion in a plane. It is assumed that the only force acting on a projectile (the object experiencing projectile motion) is the force due to gravity. But how can we define projectile motion in the real world? How are ...
The aim of this study was to investigate the effectiveness of conceptual change-based instruction and traditionally designed physics instruction on students' understanding of projectile motion concepts. Misconceptions related to projectile motion concepts were determined by related literature on this subject....
This research aimed to explore the concept acquisition in phenomena based experiential learning on projectile motion. Through phenomenon based physics' experiential learning, students analyze a phenomenon & link it with the existing concept so that it will be able to increase the acquisition of the co...

4. A ball rolled off a horizontal table will take the same amount of time to hit the ground as another dropped from the same height. 5. Projectile motion: a. horizontal and vertical components are independent, b. the horizontal component of the velocity remains constant, the vertical ...
It is concluded that perceptual-motor knowledge about projectile motion is distinct from naive, verbal-cognitive concepts of projectile motion and follows ... Krist,Horst,Fieberg,... - 《Journal of Experimental Psychology Learning Memory & Cognition》 被引量: 160发表: 1993年 Semantic knowledge cons...

Rotating flows and heat transfer levels over stationary spinning bodies with a revolution in forced flow are important in a wide range of engineering applications like missile re-entry, projectile motion, fiber coating, and rotating machine design. Many researchers have already studied its axis of re...
