The Time to Velocity calculator computes the amount of time necessary to achieve a velocity from rest based on a constant acceleration.
INSTRUCTIONS: Choose units and enter the following:
- (v) This is the final velocity
- (a) This is the constant acceleration
Time to Velocity (t): The calculator returns the duration (t) in seconds. However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for the time to reach a velocity at a constant acceleration is:
- t = v/a
where
- t is the time to reach the velocity
- v is the desired velocity
- a is the constant acceleration
One Example
This equation computes the time it will take for a massive body to achieve a chosen velocity if accelerating at some number of Gs.
One G is the acceleration of gravity at the surface of the Earth.
The default value for Gs is 40, a number that humans have been able to withstand on deceleration -- at least to survive. The actual cited value from test in the 40s and 50s was about 45 Gs actually.
