Projectiles (Edexcel A-Level Mathematics): Flashcards

Part of vector parallel to horizontal axis ($x$-axis)

Part of vector parallel to vertical axis ($y$-axis)

Magnitude of vector and angle with horizontal axis

$v_x = v cos heta$

$v_y = v sin heta$

Cosine for horizontal, sine for vertical

Remains constant

No horizontal acceleration (flat surface)

Gravity

9.81 m/s² downward

Independent of each other

Time of flight

Simplifies analysis of motion in 2D
