Archimedes was a Greek mathematician, physicist, engineer, astronomer, and inventor who lived in the third century BC. He is well known for predicting the use of calculus, and discovering an approximation of pi. While he was in Syracuse, the city was attacked by Rome in the years 213 and 212

Machines are tools used to make work easier. Some simple machines include levers, wheels, and pulleys. Mechanical advantage Mechanical advantage is an essential term in mechanics. It is a measure of the force amplification achieved by using a tool or mechanical device, or how much easier a machine makes your

The first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force. An object either at rest or in motion will stay in its current condition by inertia. If a man

Reflection happens when a wave bounces off a boundary between two materials. One example of reflection is the image above below ⬇⬇⬇. The light wave in this image is reflected in the water. When sound waves are reflected, they form what is called an echo. Absorption happens when a wave loses

Energy can’t be made or unmade. If one object loses energy, another object will gain that energy. Energy can be converted into different forms; like how a hairdryer turns energy into heat. When an object’s movement changes, its energy changes too. If a car slows down, it loses

A wave is a repeating disturbance that moves through matter or space. There are two main types of waves: mechanical and electromagnetic. Mechanical waves travel through matter, but electromagnetic waves pass through space. A wave’s crest is its highest point, and its trough is its lowest point. The amplitude

Newton's three laws of physics are some of the most basic laws of physics. They deal with motion and how it takes place. Newton's first law (the law of inertia) states that if a body is at rest or moving at a constant speed in a

Kinetic Energy = 1/2 mv² Any object that is moving has Kinetic Energy (KE). If an object is not moving, then it does not have any KE. If there are two objects moving at the same speed, but one of them has a larger mass, then the one with the

Electromagnetism is made up of two words, Electric and Magnet. When electric charges move, they create a magnetic field around them. This is known as electromagnetism. To demonstrate Electromagnetism, scientists have created an electromagnet by charging a coil of wires. What makes these magnets so useful is that they can

In this experiment, we will endeavor to explain the effects of static electricity between water and balloons that have been charged. The first step in this experiment is to procure a balloon by fair or foul means. You will have to take this 100% legitimately acquired inflatable piece of plastic

Lightning is a wonderful phenomenon that happens during thunderstorms. It is a powerful blast of electricity that can be both fantastic and dangerous. Knowing the right things about this can ensure that you are safe during thunderstorms. Lightning results from a large amount of static electricity between the ground and
