Velocity - constant acceleration

The Final Velocity calculator uses the equation (v_f = v_i + at) to compute the final velocity (v_f) of an object at time (t), knowing the initial velocity (v_i) and under constant acceleration (a).

INSTRUCTIONS: Choose units and enter the following:

• (v_i) initial velocity at time t = 0
• (t) time elapsed after t = 0
• (a) constant acceleration value

Final Velocity (v_f): The calculator computes the final velocity(v_f) in meters per second.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math/Science

The formula for the final velocity is:

     vf = vi + a•t

where:

• vf is the final velocity
• vi is the initial velocity
• a is the constant acceleration
• t is the time of motion
