The Projectile Motion Calculator is provided in support of our Physics Tutorials on Dynamics which explore Motion, the meaning of force, types of forces including gravitational force and weight, resistive forces, terminal velocity, elastic force and tension, inertia and explain Newtons Laws of Motion in clear detail with practical working examples and formula. A list of the supporting Dynamics Physics Tutorials is available at the bottom of this page. This calculator will calculate:

- The resultant of all forces acting on an object
- The acceleration caused by these forces on the object

- The position (x, y) of a projectile at any instant t during its motion when the initial velocity v
_{0}and the initial angle θ to the horizontal direction are given - The components of the initial velocity (v
_{0x}, v_{0y}) of a projectile when the magnitude of initial velocity |v_{0}| and the initial angle θ to the horizontal direction are given - The components of instantaneous velocity (v
_{x}, v_{y}) of a projectile at any instant t during its motion when the magnitude of initial velocity |v_{0}| and the initial angle θ to the horizontal direction are given - The magnitude of the instantaneous velocity |v| at a given instant t
- The acute angle α formed by the projectile and the horizontal direction at any instant t during its motion when the initial velocity v
_{0}and the initial angle θ to the horizontal direction are given - The maximum height h
_{max}the projectile can reach during its flight when the initial velocity v_{0}and the initial angle θ to the horizontal direction are given

Vertical Component of the Initial Velocity (v_{0y}) m/s | |

Horizontal Position of the Object at a Certain Instant (x(t)) m | |

Vertical Position of the Object at a Certain Instant (y(t)) m | |

Vertical Component of the Instantaneous Velocity at a Given Instant (v_{y}) m/s | |

Magnitude of the Velocity at a Given Instant (|v|) m/s | |

Maximum Height (h_{max}) m |

Please note that the formula for each calculation along with detailed calculations is shown further below this page. As you enter the specific factors of each projectile motion calcualtion, the Projectile Motion Calculator will automatically calculate the results and update the formula elements with each element of the projectile motion calculation. You can then email or print this motion calculation as required for later use.
