Ideal Projectiles (Videos 1-5)

The motion of an object falling freely in the vertical direction, and the motion of an object moving at a constant horizontal velocity, are combined to trace the motion of a projectile.

The vertical and horizontal components of the projectile's motion are independent. The vertical motion is characterized by a downward acceleration of 9.8 m/s^2 and a horizontal acceleration of zero. The equations of uniformly accelerated motion apply independently to the vertical and horizontal motions.

A basic example is worked out in which the initial velocity is in the horizontal direction. We analyze the motion then find the speed and angle of the projectile as it makes its first contact with the ground.
