Physics / Kinematics Equations

Formula for acceleration

a = (v_t - v₀) / t

Formula for final velocity

v_t = v₀ + at

Formula for distance using acceleration

d = v₀t + ½at²

Formula for distance using initial and final position

d = x_t - x₀

What does projectile motion refer to?

All objects in free-fall.

Equation to calculate the final velocity of an object without time?

v_t² = v₀² + 2ad

Let’s say this ball was launched out of the cannon, with v_net being the net velocity, or total velocity. We can denote it as v.

What’s the equation to find the horizontal component of velocity, or v_x?

v_x = v * cos(θ)

Let’s say this ball was launched out of the cannon, with v_net being the net velocity, or total velocity. We can denote it as v.

What’s the equation to find the vertical component of velocity, or v_y?

v_y = v * sin(θ)
