Projectile motion is motion in two dimensions.
00:04
If we neglect air resistance, then an object falls freely in air at the rate of acceleration due to gravity.
00:10
So in this case, we want to describe an object that is moving into dimension and it is acted only by gravity.
00:17
Well, we have already defined that as a characteristic of a projectile motion.
00:22
And so that body that undergoes, that moves in two dimension and acting and being acted only by gravity is projectile motion.
00:30
So let's discuss more thoroughly in terms of illustration how a projectile motion can be described.
00:38
So this is for example, you have a, oops, you have a clear, and a definite example for that is for a football that is a kick from the ground, the certain angle...
