Visualise projectile motion in an interesting way. Know about the time of flight formula, horizontal range, maximum height, the equation of trajectory along with examples.
Figure \(\PageIndex{1}\): Vertical vs. horizontal motion. If two objects are released simultaneously (one falling vertically and one given an initial horizontal velocity), then they both land on the floor at the same time.
The most important concept in projectile motion is that when air resistance is ignored, horizontal and vertical motions are independent, meaning that they don’t influence one another. Figure 5.27 compares a cannonball in free fall (in blue) to a cannonball launched horizontally in projectile motion (in red).
There is no vertical component in the initial velocity (\(\mathrm{v_0}\)) because the object is launched horizontally. Since the object travels distance \(\mathrm{H}\) in the vertical direction before it hits the ground, we can use the kinematic equation for the vertical motion: \[\mathrm{(y−y_0)=−H=0⋅T−\dfrac{1}{2}gT^2}\]
Understand the motion of projectiles and satellites by separating their motion into horizontal and vertical components for National 5 Physics.
Determine the location and velocity of a projectile at different points in its trajectory. Apply the principle of independence of motion to solve projectile motion problems. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity.
