Let's talk about how to get your dog to stop chewing furniture. Now, there are lots of reasons that dogs do that, especially puppies that are teething, and they're trying to explore the world by chewing on everything, and so it can be quite a nuisance, obviously.ancel. Getting dogs to stop chewing on furniture can be done by providing lots of chew toys, using positive reinforcement when they chew on appropriate things and spraying a bitter product on the furniture they like to chew.
For other uses, see Escape velocity (disambiguation). In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from Earth is about 40,270 km/h (25,020 mph). More generally, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.
For an actual escape orbit a spacecraft is first placed in low Earth orbit (160â2,000 km) and then accelerated to the escape velocity at that altitude, which is a little less â about 10.9 km/s.or an object of mass the energy required to escape the Earth's gravitational field is GMm / r, a function of the object's mass (where r is the radius of the Earth, G is the gravitational constant, and M is the mass of the Earth, M =5.9736Ã10 24 kg).
