Isn’t going up with velocity greater than 9.81 m/s be enough to escape earth’s gravity?
In: Physics
You’re mixing up velocity and acceleration.
The acceleration due to gravity is 9.81 m/s**^2**
Theoretically, any speed above 0 and you could get into space if you kept it up. However, due to the fact that gravity is constantly pulling you down, you need to be putting work in constantly to counteract gravity and keep going up.
