Projectile Position at Time Calculator

About this calculator

A projectile launched at an angle follows two independent motions at once: constant horizontal velocity (ignoring air resistance) and vertically accelerated motion under gravity. Its position at any time t is given by x = v₀·cos(θ)·t for the horizontal distance and y = v₀·sin(θ)·t − ½g·t² for the height, where v₀ is the initial speed, θ the launch angle, and g gravitational acceleration (9.8 m/s²).

This calculator plugs your initial velocity, launch angle, and a specific time into those two equations to find exactly where the projectile is — not just at the peak or landing point, but at any moment during the flight. It's a core tool in introductory physics courses for checking projectile motion homework and visualizing how horizontal and vertical motion combine independently.
