Projectile Motion Calculator

How to use the Projectile Motion Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

InitialHorizontalVelocity = InitialVelocity× cos(angle)

InitialVerticalVelocity = InitialVelocity × sin(angle)

TotalTime= (InitialVerticalVelocity + (InitialVerticalVelocity ^2 + 2 × g × InitialHeight)^(1/2))/g

Distance = HorizontalVelocity×TotalTime

InitialVelocity = Distance × g / sqrt(2 × Distance × g × one_way(sin(angle) × cos(angle)) + 2 × g × InitialHeight × one_way(cos(angle)^2))

MaximumHeight = InitialVerticalVelocity ^2/(2×g)+InitialHeight

The calculator uses 6 further relationships to link its other values.
