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 […]
Everything in the Universe has gravity, including you! Gravity attracts objects toward each other. The larger an object is, the more gravity it has. For example, a star, like the Sun has significantly more gravity than an asteroid. Like all fields, including magnetism, static electricity, and yes, gravity, the attractive force increases the closer you […]
Have you ever flown in an airplane? If you have, then what did you do during your flight? Did you read a book? Watch a movie? Sleep? Whatever you did, you probably trusted that the pilot knew what they were doing, and that they would get you to the correct destination. Did you consider though […]
Everything in the Universe is made up of matter, which means that it has mass. When gravity is present, everything in the Universe also has weight. These two attributes (mass & weight) are similar but they are not the same thing. Mass refers to the amount of matter in an object. Objects with more mass […]
Throughout human history people have been fascinated by the movements of the stars, planets, moon, and sun. One of the most impressive things for these ancient humans to witness were eclipses. Both of the sun and of the moon. A Solar Eclipse happens when the moon passes in front of the sun, blocking its light. […]
One of the most prominent features of the night sky is our Moon. The way the Moon looks constantly changes in a predictable pattern. We call these changes phases. What are the phases of the moon, and what causes them? There are eight phases of the moon, and they are: New Moon, Waxing Crescent, First […]
Our Solar System is made up of eight planets, each with its own unique characteristics. Here’s a brief overview of each one: Mercury is the closest planet to the sun and has very little atmosphere. As a result, it experiences extreme temperatures, with the days being incredibly hot and the nights being very cold. Venus […]
The moon is a natural satellite of the earth, consisting of rock, dust, and ice. It was formed about 4.5 billion years ago, soon after the formation of the earth. When a large planetoid collided with the earth, the resulting debris formed a ring around the earth. This ring eventually coalesced to form the moon. […]
