Assuming gravity is downwards along the axis of the actuator (and needs to be considered), what mass is the actuator lifting?
Force = Mass * Acceleration
Normally the height and velocity are not needed unless there are changes in the acceleration or other factors.
assume the mass is 1kg
Then F = M * a = 1 Kg * 0.5 m/s^2 = 0.5 Kg-m/s^2 = 0.5 N
thank you sir for the help
