Projectile motion is the motion of an object through the air that is affected by gravity. This type of motion follows a curved path known as a parabola.
Regular motion follows a straight path, while projectile motion follows a curved path. Additionally, regular motion is not affected by gravity, while projectile motion is.
The equation for projectile motion is y = y0 + v0yt - 1/2gt2, where y represents the vertical position, y0 represents the initial vertical position, v0y represents the initial vertical velocity, t represents time, and g represents the acceleration due to gravity.
The angle of projection, also known as the launch angle, affects the range and height of a projectile. The optimal angle for maximum range is 45 degrees, while the optimal angle for maximum height is 90 degrees.
Air resistance, also known as drag, can affect the path and speed of a projectile. It can cause the projectile to slow down and deviate from its expected path. This is why in real-life scenarios, the path of a projectile is not always a perfect parabola.
