A specialized instrument for measuring various types of speeds and velocities accurately.
Linear velocity is calculated by dividing the displacement (distance) by the time taken. Formula: v = d / t.
Angular velocity is the rate of change of angular position. For a rotating object, if you know the RPM (Revolutions Per Minute) and the radius, you can calculate both the angular velocity (rad/s) and the linear tangential speed.
Projectile motion involves decomposing initial velocity into horizontal (X) and vertical (Y) components using trigonometric functions (sine and cosine of the launch angle).
By tracking multiple time points over a set distance, you can analyze acceleration and average velocity trends to improve athletic performance.
