Although distracting yourself from your emotions is not the best option, it can help you feel better momentarily. Things like exercising, gaming, or working on a hobby may take your mind off your sibling's rejection and the associated feelings. However, the only healthy way to deal with your emotions is by addressing them. Exercise can significantly improve your mood and help you fight off depression. One of the first steps that you can take when dealing with negative emotions is to write them down. Write about your how you feel in a journal or a diary. Share how your sibling's rejection made you feel and what that means for your relationship with them. Putting your feelings on paper can help you better process things. You might consider writing a letter to your long-lost sibling that expresses how you feel. However, if you feel like sending the letter, think about it for at least a week before mailing it. When dealing with your sibling's rejection, turn to your friends and family for support. Talk with them about how you feel. A good friend will listen to you and help you better understand the situation. Talking with shared family members of the long-lost sibling may be more complicated, especially if they have a relationship with the sibling. Feel out these situations and determine who will be a good confidant. When discussing your feelings with family or friends, avoid blaming yourself. Try not to dwell on negative thoughts about yourself or the sibling who rejected you. Use facts to understand the rejection. Allow time for positive talk during these sessions, as such positive interactions will give you natural emotional pain relief. Talking with other people who have experienced a similar type of rejection may help you make sense of your sibling's rejection. Look for organizations and groups in your area that bring together people who have been shunned or rejected by their family members. You can also go online and join a chat group for people who are in situations similar to yours. Joining a support group will allow you to share your feelings with people who can relate to your situation and help you feel less alone. Expressing your feelings to both yourself and others can help clarify the event. It may help give you a deeper understanding of why your sibling did not want to meet. If you are struggling with the rejection, a counselor or therapist may be able to help you process your emotions. They will talk with you about the rejection and any associated feelings. After meeting with a mental health professional for a few sessions, you may have new insights into the rejection that help you feel better about the situation. Go online to find mental health professionals in your area. Make sure that they are certified through your state's psychological board.

summary: Focus your attention on other tasks. Write about your feelings. Talk to a friend or family member. Join a support group. Seek professional help.

Newton's first law tells us that any object in motion will continue to move in the same direction at the same speed unless another force acts on it to change its motion. If an object is stationary, it will remain stationary. This first law is sometimes referred to as the law of inertia. This law states that an object moves with a constant velocity (speed and direction) unless there is a nonzero (unbalanced) net force acting on it. An object that is not moving has a net force of zero acting on it. As the force acting on an object increases, the acceleration of the object increases. Force alone does not determine the acceleration of an object; the object's mass also plays a critical role. The larger the mass of an object, the slower it will accelerate. This relationship can be explained using the formula F = ma where "F" is the force acting on the object, "m" is the mass of the object, and "a" is the acceleration of the object. Another way to think about this law is that an object will not accelerate unless there is an unbalanced (or net) force acting on it. The third law states that every action has an equal and opposite reaction. When a force acts on an object, there is a force of the exact same magnitude that pushes back in the opposite direction to the original force. For example, when you sit down on a bench, you are exerting a downward force on the bench, but the bench is exerting an equal upward force on you. This law states that all forces come in pairs. Conservation of energy states that "energy can be neither created nor destroyed." In other words, energy remains constant in an isolated system. The same goes for momentum and angular momentum: in an isolated system momentum and angular momentum remain constant. It's important to note that an isolated system is one in which there are no outside forces acting on it. In reality, an isolated system doesn't really exist, but it is a useful model to describe the basic principles of the physical laws of nature.

summary: Define Newton's first law of motion. Understand Newton's second law of motion. Learn Newton's third law of motion. Know the laws of conservation of energy, momentum, and angular momentum.

Some dogs are nervous about car travel because they feel nauseous and associate journeys with feeling ill and travel sickness. Recognize the signs of motion sickness, the most obvious of which is heavy drooling. Strings of saliva hanging from the dog's lips is a sure sign of motion sickness. In addition, all dogs react differently but some hang their heads and look troubled, others may try to pace, and some will whimper. Those dogs who suffer from motion sickness will need medication to travel well. You will need to speak to your vet about a safe medication to counteract the nausea. It might be that the dog always needs medication for long journeys, but you may well be able to retrain it to accept short journeys without illness. Do not shout or chastise the dog if it vomits. It cannot help being sick and being chastised only adds to its apprehension and increases the trauma of the experience, which will make it even more anxious. If you know your dog gets travel sick but have to make a journey, such as to the vet to get travel sickness meds, then seat it on a puppy pad so that the mess can be easily cleaned. It usually helps a dog if it can see out of a window. If you have a toy or small dog, consider getting a travel pod which raises it up off the seat in a safe way, so it can see out. For medium sized dogs, have a certified crash-tested harness and seat the dog on a back seat so it can see out. For large dogs, consider putting the dog in a crate, so they are safe and can see out. You can also put a blanket underneath where the dog will be sitting. It should be a blanket that the dog uses regularly, so its smells will be familiar to the dog. Avoid using human anti-motion sickness medications unless you have checked it out with your vet first. These are not approved for use in dogs, so the side effects have not been fully tested, and the possible reactions with other drugs is unknown. On a practical level, dogs metabolize drugs differently than people, so there is a distinct possibility that those human drugs won't be effective. The best medication for motion sickness is a prescription drug called Cerenia (maropitant) which is available as an injection (given by the vet) or tablet. Both forms work for 24 hours. This medication is superior to others because it acts on the nausea center in the brain, and switches off all feelings of nausea and sickness. Some owners find giving their dog Bach flower remedies, commonly known as Rescue Remedy, helps, but this is anecdotal. This is a liquid and you place a few drops on the dog's tongue. The Bach flowers are dissolved in alcohol and one possible explanation that some dogs seem to benefit is that they are given the equivalent of a small alcoholic drink.
summary: Assess whether your dog has motion sickness. Be prepared for the dog to be sick. Place your dog in a spot in the car where it can see out. Consult with your vet about whether your dog needs medication to prevent nausea. Consider alternative treatments.
