The kinematic equations program allows you to quickly compute one physics kinematics value, when you know several other kinematic values. The supporting program automatically determines which kinematics formula to use! Surprisingly the same program is used for both translational and rotational kinematics. This is based on the following Rosetta Stone.
Kinematic equations -- Rosetta Stone
Value type | Translational value | Rotational equivalent |
---|---|---|
Displacement | x (meters) | Θ (angular displacement, in radians) |
Velocity | v (meters / second) | ω (angular velocity, radians / second) |
Acceleration | a ( meters / second2) | α (angular acceleration, radians / second2) |
Mass | m (kg) | I (moment of inertia) |
Momentum | p (mv) | L (angular momentum: I ω ) |
Force | F (ma) | Τ (torque: I α ) |
Click either the TranslationKinematics or RotationalKinematics tab.
Enter the values that you know, for the problem you are trying to solve.
Put a question mark (?) for the value you want to compute.
Put dashes (-) in other value fields.
Value | Example | Description |
---|---|---|
Acceleration | 5 | 5 m / s2 |
Time | 7 | 7 seconds |
Initial velocity | 0 | 0 m/s (the object is initially stationary) |
Final velocity | 5 | The final velocity is 5 m/s |
Displacement | 55 | The object moved 55 meters |
