Final answer:
An escape ramp, in physics, is the speed necessary to overcome gravitational pull when leaving an object's atmosphere. For instance, rockets must achieve a speed greater than the escape velocity of Earth to travel to other celestial bodies in space.
Step-by-step explanation:
An escape ramp, in the context of physics, refers to the speed needed to overcome the gravitational pull of an object or group of objects. It is commonly used when discussing rockets or spacecraft leaving the Earth's atmosphere and traveling to other celestial bodies.
For example, when sending a rocket from Earth to another planet, it must reach a speed greater than the escape velocity of Earth to break free from its gravitational pull and venture into space.
