As you would know if you have a kitten, they only get worse as they age. This is intensely true for my kitten, Mia. Not only does she constantly escape her room, but she has figured out that my computer screen is touch screen, and wreaks havoc on whatever I am doing on the internet by touching it.
I often have to pick her up to try to prevent her from destroying something. She only weighs two pounds, even though she is 13-14 weeks old. I don't have to do much work because of her size, but
One comment I received on a previous blog about backpacks was about a backpack literally breaking your back. I decided to do some research on the topic. It appears that a vertebrae in your spine can withstand about 500 lbs of force, which is about 2225 N of force. In order to do some damage to your spine, you would need to have a backpack weigh this much in newtons. This means that your backpack would have to have a mass of 227 kg, or almost 500 lbs to do real damage to your back.
To put t
I work at the bar, Murph's, on Friday and Saturday, and one of my tasks is to refill ketchup bottles. In order to get the ketchup to the neck of the bottle, I hold it by the bottom and spin it in a vertical circle.
This works because of centripetal force. You might be saying, however, that centripetal force pulls objects towards the center of the circle. While this is true, it acts on less dense materials at a greater magnitude. Inside the ketchup bottle, there is only air and ketchup. Sin
There are several ways in which cars demonstrate physics. For one, when you turn, hit the gas or brake, you can see the property of mass called inertia. Anybody or anything in the car tends to continue traveling in the direction the car was originally going in or stay still if the car was stopped.
Also, the physics behind tires show how cars move. As the tire spins, it uses the friction between it and the road to push the car forward. This is why in snow or mud, where there is little fricti
One thing I do on a daily basis is drop things. For example, pieces of paper or folders. When these things fall, they have the force of mg down, and the force of air resistance up. The paper will reach a terminal velocity and continue to fall at this velocity until it hits the ground. The force that the paper exerts on the floor is equal to the force the floor exerts on the paper. The coefficient of friction between the tile floor and the paper is likely small because the tile is smooth and the
