This is completely random, but as I was pondering ideas for a blog I discovered that there is a lot of physics involved in toasters!
Most appliances that heat up, such as hair dryers, irons, and toasters, work by changing electrical energy into heat energy. Toasters are plugged into a source of electricity. From that source, the electric current runs down the wire and into the toaster. The inside of each appliance contains loops of different metals. The electricity does not easily flow thr
Have you ever been curious as to how a balloon can magically stick to a wall after rubbing it against some sort of material? This happens because of Static Electricity.
Static Electricity is a familiar electric phenomenon in which charged particles are transferred from one body to another. When you rub your hair or a sweater against a balloon, charge transfer occurs, and Static Electricity is produced. In simpler terms, if you rub a balloon against your sweater, the balloon will steal electro
Today, while looking in the mirror, I suddenly became very curious as to how mirrors work. I remember talking about mirrors in physics class, especially when talking about reflection, but there is even more to it!
The first thing I learned is that there are three types of mirrors: plane, convex, and concave. I will talk about plane mirrors. With plane mirrors, the image is always upright, virtual, and the same size.
The Law of Reflection is a huge part of how plane mirrors work. This law
Did you know that when a dog's sense of hearing fully develops, it can hear about four times the distance of a human with normal hearing? How is this possible?! Well, it actually has a lot to do with physics.....
Humans can typically hear sounds from within the frequencies of 20 Hz and 20,000 Hz, meaning they usually can't hear any sounds below the frequency of 20 Hz or anything above the frequency 20,000 Hz. Frequencies that are out of the range of human hearing are untrasonic (cyclic sound
Here on earth we are so used to seeing heavier objects fall faster than lighter objects; if I were to drop a bowling ball and a piece of paper at the same time, it is pretty obvious that they would fall at different rates. The paper has a small mass compared to it's surface area, and the bowling ball has a larger mass compared to its surface area. It takes longer for the piece of paper to push away the air molecules, than the bowling ball.
So how come on the moon, a feather and a hammer fall
