• An object thrown horizontally will fall at the same rate as an object that is dropped. The velocity in the horizontal direction does not (patt) affect the velocity and acceleration in the vertical direction. Balls Fall vertically together as projected balls moves to the right
• Neglecting air resistance, a horizontally projected object essentially travels in a horizontal direction with a constant velocity (no acceleration in that direction) while falling vertically under the influence of gravity. The resulting path is curved arc.
• All objects thrown vertically begin falling as soon as they leave the hand.
• If an object is projected at an angle of Greek theta) to the horizontal, it will follow a symetric curved path, Where air resistance is again neglected
• The curved path is essentially the result of the combined motions in the vertical horizontal direction. The projectile goes up and down vertically, while at the same time travelling horizontally with a constant velocity
• The vertical motion near the maximum height, velocity is quite small going to zero and the increasing from zero. The combination of the slow vertical motion and the constant horizontal motion gives the ilusion that the player is hanging in the air
• Is a ball or other object is thrown at various angles, the path that it takes will depend on the angle at which is it thrown. Neglecting air resistance, each path will resemble. The range or horizontal distance the object travels is maximum when the object is projected at an angle of 45° relative to level the ground.
• HORIZONTAL PROJECTILES


  When an object is launched or thrown completely horizontally, such as a rock thrown horizontally off a cliff, the initial velocity of the object is it's initial horizontal velocity Because horizontal velocity doesn't change, the velocity is also the object's final horizontal velocity, as well as it's average horizontal velocity.
• Further, the intial velocity of the projectile is zero
• ANGLED PROJECTILES


  You need to breat the initial velocity vector up ihto x and y components in the same manner as covered in the components of vectors math review section. Use the components for your intial velocities in your horizontal and vertical tables.
• NOTE: Symmetry motion also applies to the parabola of objectile motion...
