Motion Under Gravity (Leaving Cert Applied Maths): Flashcards

$9.8 \text{ m/s}^2$

Uniform acceleration

$+g$ or $+9.8 \text{ m/s}^2$

$-g$ or $-9.8 \text{ m/s}^2$

$s = ut + \frac{1}{2}at^2$

$v^2 = u^2 + 2as$

$v = u + at$

Zero or $0 \text{ m/s}$

They are equal

Downwards (towards Earth)

When objects move upwards against gravity

Constant at $9.8 \text{ m/s}^2$ towards Earth
