Newton's second law of motion states that when the forces acting on an object are unbalanced, the object will accelerate. This acceleration is dependent upon the net forces that act upon the object and the object's mass. Using this law, acceleration can be calculated when a known force is acting on an object of known mass. Newton's law can be represented by the equation Fnet = m x a, where Fnet is the total force acting on the object, m is the object's mass, and a is the acceleration of the object. When using this equation, keep your units in the metric system. Use kilograms (kg) for mass, newtons (N) for force, and meters per second squared (m/s2) for acceleration. To find the mass of an object, simply place it on a balance or scale and find its mass in grams. If you have a very large object, you may need to find a reference that can provide you with the mass. Larger objects will likely have a mass with the unit of kilograms (kg). For this equation, you will want to convert the mass into kilograms. If the mass you have is in grams simply divide that mass by 1000 to convert to kilograms. A net force is an unbalanced force. If you have two forces opposing each other and one is larger than the other, you will have a net force in the direction of the larger force. Acceleration happens when an unbalanced force acts on an object, causing it to change speeds towards the direction the force is pushing or pulling it. For example: Let's say you and your big brother are playing tug-of-war. You pull the rope to the left with a force of 5 newtons while your brother pulls the rope in the opposite direction with a force of 7 newtons. The net force on the rope is 2 newtons to the right, in the direction of your brother. In order to properly understand the units, know that 1 newton (N) is equal to 1 kilogram X meter/second squared (kg X m/s2). You can change this formula around to solve for acceleration by dividing both sides by the mass, so: a = F/m. To find the acceleration, simply divide the force by the mass of the object being accelerated. Force is directly proportional to the acceleration, meaning that a greater force will lead to a greater acceleration. Mass is inversely proportional to acceleration, meaning that with a greater mass, the acceleration will decrease.

summary: Define Newton's Second Law of Motion. Find the mass of your object. Calculate the net force acting on your object. Rearrange the equation F = ma to solve for acceleration.

Go ahead and choose a few of the lovely round fruits and save the brown seeds inside. Lychee fruit will be available during the typical lychee season, usually throughout May, June, and July in the Northern hemisphere. Make sure the fruit you get is fresh and completely ripe. The skin will be dark red, almost purple, and the bumps will flatten due to the amount of juice and sugar inside. Large seeds germinate better than smaller seeds. Seeds are only good for a few days once they've been removed from the fruit, so plant them right away. Don't buy lychee fruit until you're ready. There are plenty of online retailers that will ship you lychee seeds that are ready for planting. Just be aware that seeds taken from fresh fruit have a higher germination rate. Enjoy the delicious snack first, then clean off all remnants of fruit and you'll have a beautiful burgundy seed that's ready to become a tree. Get the seed wet, and then roll it gently around in the paper towel. This will remove any lingering debris. To increase the chance of germination, fill a cup or bowl with water and submerge the seed completely. After a few days, the brownish husk will begin to crack, which is a telltale sign that the seed is about to sprout. The water can be tap or bottled. Replace the water every day to maintain freshness.

summary: Buy lychee fruit from a grocery store or farmer's market. Purchase seeds online if you can't find fresh fruit. Clean the seed with water and paper towels. Soak the seed in room-temperature water for 3 days.

Once you have identified your animal, learn everything you can about it. What does it eat, and where does it live? Read about its history, behaviors, and the way it is portrayed in literature and the media. What does this animal represent? An animal's particular wisdom is called its "medicine," or power. This medicine can be used to help during a time of need. For example, a hawk's medicine might be its ability to see clearly when others cannot. If possible, spend time near your animal's habitat. Do not be disruptive, but try to learn as much as you can about how the animal exists in the wild. Take what you have learned and use it to help you deal with making big decisions, confronting difficult situations, and reaching your goals. You can draw on your animal's wisdom in everyday life, too, in your treatment of others and the earth. Pay close attention each time your animal appears to you in any form. Do your best to interpret the messages the animal seems to be sending. Remember, the messages will not be straightforward, since animals do not communicate the same way humans do, so you will have to do some deep thinking to understand. Here are some questions to ask yourself: What emotions do you feel when the animal comes? Does the animal seem to be a sign of foreboding or comfort? Does the animal seem to be leading you in a certain direction? It is believed in shamanism that you gain a deeper connection with your spiritual animal by honoring it. In doing this, you are letting it know that its assistance in helping you with your life is appreciated. You can do this by standing up for the environment and animal rights and, in particular, the well being of your spirit animal. Remember that each time an animal species goes extinct, we lose the wisdom of that animal.
summary: Learn about your animal. Apply your animal's wisdom to your own life. Be open to messages. Honor your animal.
