A projectile is an object upon which the only force acting is gravity. Many projectiles not only undergo a vertical motion, but also undergo a horizontal motion. That is, as they move upward or downward they are also moving horizontally. There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion must be discussed separately. The goal of this lab activity was to discuss the horizontal and vertical components of a projectile’s motion; specific attention was given to the presence or absence of forces, accelerations, and velocity.
If you’re slightly confused, at this point, simply ask our P6 Science students about this. They have recently completed a “Gravity and Acceleration” activity in the Science Lab, and they can easily clarify things for you.
