Have you ever stood on a scale to see how much you weigh? Weight is a measure of how heavy something is. It is affected by the Earth or any other planet that pulls on objects due to their gravity. The more matter an object has, the stronger gravity will pull on it, and as […]
Have you ever stopped to think about what everything in the universe is made of? Well, everything in the universe is made of something called matter. Matter is anything that takes up space and has mass. That means everything you can touch and see, like your toys, books, and even the air you breathe, is […]
Pulsars are some of the most fascinating objects in the universe. These spinning neutron stars emit intense beams of electromagnetic radiation, which can be detected on Earth as regular pulses of radio waves or light. Neutron stars are the collapsed cores of massive stars that have gone supernova. These stars are incredibly dense, with a […]
A supernova is a powerful explosion that occurs at the end of a star’s life. These explosions are so bright that they can outshine an entire galaxy for a brief period of time, and they are responsible for releasing huge amounts of energy and matter into the universe. There are several different types of supernovae, […]
Legend states that gravity was discovered by a man named Issac Newton as an apple fell from a tree and hit him in the head. The more you consider this story though, the less likely it seems to be factual. Did no one understand gravity before Newton? Was he the first person to realize that […]
Issac Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This law is the basis for many things we see in everyday life, from the way a rocket propels itself through the air to the way a person pushes against the ground to walk. It is also […]
Issac Newton’s second law of motion states that the acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass. In other words, the heavier an object is, the more force is required to accelerate it. The formula for this law is: F = ma Where F […]
Issac Newton’s first law of motion is the law of inertia. It states that an object will remain at rest or in motion until an external force acts upon it. What does this mean? Imagine that an object, such as a ball, is moving through space. How long will that ball continue to move? According […]
Do you play a sport, or belong to a dance club? Do you swim on a swim team? How does everyone on your team or club know when to meet for practice, or to play in a game or competition? By selecting a specific time to meet, you insure that everyone arrives at around the […]
Do you know where you live? With the hustle and bustle of everyday life, it is easy to forget that the human family lives on a small blue planet named Earth. All around us we see trees, animals, cars, buildings, farms, factories, stores, and other natural and man-made structures. With all of these every day […]
