My Background

What is Thrust to weight ratio?

To safely launch a rocket the thrust to weight ratio should be at least 5 to 1

For example, if a rocket weighs 0.4 kg, and the motor has a thrust of 15 Newtons, is this safe?

Answer: The weight of the rocket is 0.4 x 9.8 = 3.9 N. Thrust is 15 N. The thrust to weight ratio is thus 15:3.9, or 3.8:1. This is less than 5:1 so the launch would be unsafe.
