Motion in a Gravitational Field (Grade 12 NSC Matric Physical Sciences): Quizzes

Any object moving under gravity only

$g = 9.8$ m⋅s⁻²

Downward toward Earth's centre

$v = 0$ m⋅s⁻¹

Still $g = 9.8$ m⋅s⁻² downward

Time up = time down to original position

$v_i$ depends on launch; $g$ is constant

$v^2 = v_i^2 + 2gs$

$g = -9.8$ m⋅s⁻²

Symmetric
