The physics definition of work is the process of moving an object by applying a force. Everyday, without even noticing we are putting in work to move an object. Work must involve displacement from the force trying to move the object. Typing on a keyboard, pushing open a door, and many sports all involve work. Soccer for example, is a sport based on people applying a force to a soccer ball to get it down a field in hopes of scoring.
Have you ever taken a plane ride? Isn't it weird to think about how this huge mass is soaring through the sky without falling to its death? How is this remotely possible? Well simply put, physics!
After breaking it all down, an airplanes flight ability comes down to one key thing, and that is the balance of force. If the upward force of the object is greater than that of the force being pushed onto the object, the object will rise. If the force of gravity to too great, then the object will no
After months of cold, bone chilling weather, the sun finally came back out. To celebrate this beautiful day, we took a quick trip to the beach. As we walked the pier, we noticed how the waves flowed back and forth toward the shore. Although the sunset and waves created a pretty view, we cannot ignore the physics behind the beauty.
A wave can be described as a disturbance that travels through medium from one location to another location. But what causes the disturbance? The winds in the air cau
Have you ever wondered how Princess Rapunzel could bare so much weight as she pulled up her prince? How could her neck not break? How could she not lose her skull? In reality, what she did was impossible. The physics of that fairytale made her story impossible.
But the recent developments have made her story slight more realistic. In more modern stories, Rapunzel no longer just throws down her hair. In newer version, she wraps her hair around something. Even something small like a bed post woul
We are all told that we should never text and drive. It's a distraction on the road that people everywhere are guilty of. Our nation loses thousands of lives due to texting and driving accidents, but people still don't seem to understand the dangers of it. But how do we know when an accident was caused by someone being distracted by their cell phones? How do we know the person didn't just have an unfortunate accident? Simple, physics.
Using simple equations, like distance times time, we are ab
While in Cambodia, I got to ride all different types of scooters and motorcycles. All over people, you'll find people getting around using motorcycles and mopeds. Motorcycles include different parts of physics because you deal with dynamics, acceleration, and gravitational force. Trying to keep your body centered to prevent from an accident, while the motorcycle accelerates all has to do with physics. Not only that, but when turning a motorcycle, the bike must lean without falling totally over.
Bounce as high as you can. How high could you jump on flat ground? Now jump on a trampoline. How high did you go that time? A lot higher right? So why is that? What make us bounce so much higher when on a trampoline compared to when on the ground? Simply put, it's the Potential and Kinetic Energy of the trampoline. The potential energy that is stored in the springs, along with the gravitational potential energy and the kinetic energy while you move, allows for a higher bounce.
Skyzone, a popul
I always wondered why is hurt so much when you punched something. Besides the obviously answer of: "It's a hard surface against your little hand" I never truly had an answer until we learned about Newton's Laws. Newton's Third Law helped to answer my question. According to Newton, when you put any force on any object, the amount of force you exert will be exerted back on you. Punching a wall, punching a person, or anything like that results in pain because all the force you exerted comes right b
Building the catapult involved taking many measurements to find how to make the catapult go as far as it could possibly throw a soft ball. To get the furthest distance we had to measure our catapult at an angle of 45 degrees. That would allow us to reach a farther distance than if the catapult were set at any other angle. Later, we added bungee cords, but knew that the more tension on the catapult the further the ball would fly.
We took measurements of every PVC pipe used and every piece of woo
When you turn on the oven, the air is heated by conduction. Conduction is the spontaneous transfer of heat from a region of higher temperature to a region of lower temperature. Due to convection, the air is circulated due to the different densities between hot and cold air. Next, the baked good will also be heated through conduction, once placed in the oven.
The infrared light waves, also known as heat energy will pass through the entire mixture and the overall temperature of the cake will incr
