Player Not Falling After Thrown

VIDEO I’m working on a Pygame project where I have a player that can be thrown towards the pointed aiming dots when the space bar is clicekd. The throwing motion works as expected; however, I’m encountering an issue with the player not falling back down after being thrown like a bell shape. . Any suggestions or insights into what might be causing this issue would be greatly appreciated!

# Inside the main game loop
if keys[pygame.K_SPACE] and not player1.isThrown:
    player1.isThrown = True
    player1.throwCount = 0
    player1.angle = math.atan2(dot.y - player1.y, dot.x - player1.x) + math.pi / 2 

if player1.isThrown:
    throw_distance = player1.throwSpeed * player1.throwCount
    player1.y -= throw_distance * math.cos(player1.angle)  
    player1.x += throw_distance * math.sin(player1.angle) 
    player1.throwCount += 1


# Falling motion after the throw
if not player1.isThrown and player1.y < 400:
    fall_speed = 5
    player1.y += fall_speed

    if player1.y > 400:
        player1.y = 400

>Solution :

Increase the self.throwSpeed:

self.throwSpeed = 10

but do not increment the movement vector:

throw_distance = player1.throwSpeed * player1.throwCount
player1.throwCount += 1

Falling is an accelerated movement, so the falling speed must be increased in each frame:

fall_speed = 0
run = True
while run:
    # [...]

    if keys[pygame.K_SPACE] and not player1.isThrown:
        player1.isThrown = True
        player1.angle = math.atan2(dot.y - player1.y, dot.x - player1.x) + math.pi / 2 
        fall_speed = 0

    if player1.isThrown:
        player1.y -= player1.throwSpeed * math.cos(player1.angle) 
        player1.x += player1.throwSpeed * math.sin(player1.angle) 
        player1.y += fall_speed
        fall_speed += 0.5
        if player1.y > 400:
            player1.y = 400
            player1.isThrown = False
            fall_speed = 0

    pygame.display.update()
