P6 - Projectile Motion

any object which projected by some means and continues to move due to its own inertia (mass).

Projectile

The path of a projectile is called its?

trajectory

The force of primary importance acting on a projectile is?

gravity

A projectile is any object with an initial non-zero. Horizontal velocity whose acceleration is due to?

gravity alone

The trajectory of a simple projectile is a?

parabola

can be described as the motion of an object (called the projectile) that is moving in the x-y plane. This just means that the motion of the projectile is the vector sum of its horizontal and vertical motion.

Projectile motion

Projectile moves in TWO dimensions which is?

Horizontal and Vertical

In this component velocity never changes because it covers equal displacements in equal time periods. This means the initial horizontal velocity equals the final horizontal velocity

Horizontal

In this component the velocity changes due to gravity, and does NOT cover equal displacements in equal time periods.

Vertical

In Vertical “Velocity” Component, Both the MAGNITUDE and DIRECTION change. As the projectile moves up the MAGNITUDE DECREASES and its direction is Upward. As it moves down the MAGNITUDE INCREASES and the direction is? .

DOWNWARD

Together the components of magnitude and direction produce what is called a trajectory or path. This path is _______in nature.

parabolic

Along the horizontal, the velocity is constant and free from acceleration (a = 0). The acceleration is only present in the vertical. The kinematic equations still apply in projectile motion. A point to consider in projectile motion is that at its maximum height, the this component of the velocity becomes zero.
