We define and discuss how to draw Free Body Diagrams which are also called Force Diagrams. In addition we define the force normal and the force applied. Force of friction and center of mass are briefly discussed, however, a much more detailed discussion of each is left for later lessons.

Today was one of those days when all the roads were covered in snow, which is bad for driving and even worse for running. A few steps in that salty slush and you'll be slipping all over the place. What I've found is that snow sticks to the bottom of my shoes and stays there, so rather than my rubber soles trying to get traction with snow, there is just more snow trying to get traction with the snow. This drastically reduces the coefficient of static friction between my shoes and the road, causing my feet to slip every step which gets really annoying after about 20 feet. Also less frictional fo

The Benefit of Antilock Brakes
pavelow posted a blog entry in Blog Having Nothing to do with Physics
Bob is barreling down the thruway in his truck at 40 m/s when a crash occurs in front of it. The driver wants to stop in the shortest distance possible. He slams on the brakes. Before the invention and implementation of the Antilock brake system, or ABS, the truck's tires would have locked up and the truck would have slid into the crash. Why? When brakes cause tires to lock up, the type of friction between the tires and road changes from static friction to kinetic friction. This decreases the total force of friction between the surfaces. Because of the decrease in force opposing the tru 
When taking corners quickly, the biggest worry most drivers should have is slipping and losing control of the car. This happens when a driver takes the corner too fast. The physics of taking a flat corner depends on the equation vmax = Sqrt(mu*r*g). mu, the coefficient of static friction, is constant, as is g, the acceleration due to gravity. Therefore, a driver trying to take a corner as quickly as possible would like to make the radius of the turn as large as possible to allow for a higher vmax, keeping his car from slipping at higher speeds. But how? Doesn't a road have a defined radius?

We are having trouble understanding the concept of question number 13 below: (we figured out the first ones OK) Base your answers to questions 9 through 13 on the information below. A manufacturer’s advertisement claims that their 1,250kilogram (12,300newton) sports car can accelerate on a level road from 0 to 60 miles per hour (0 to 26.8 meters per second) in 3.75 seconds. 9. Determine the acceleration, in meters per second2, of the car according to the advertisement. 10. Calculate the net force required to give the car the acceleration claimed in the advertisement.

So my dog just growled and I thought I should do a blog post on her since I cannot think of any ideas. I was just playing fetch with Pearl in my house, which has hard wood floor (the real kind). Pearl ran on the area carpet onto the hardwood, but when she tried to stop, she ended up skidding past the ball into the fireplace (its just a hole in the wall made of brick so she was unharmed). So here's the playbyplay: When Pearl was running on the carpet, she was able to get enough contraction to accelerate forward. Once Pearl hit the hardwood floor, she couldn't accelerate or decelerate as

Okay, so today i was skateboarding, thinking about blog posts, but also thinking about all the forces and such that go into just doing a few tricks. Such as the kickflip, where the board spins on the lengthwise axis (for those of you not skateboarding people). It needs the physics of the ollie, which is downward force on the tail, force upwards because of the fulcrum of one of the axles, and forward momentum from pushing with the front foot, for an inertial fulcrum that rotates the board up into the air. From there, the rotation is caused by a downward force on the edge of the board, but, the

Drifting had a lot to do with physics. I'm just gonna start right in with friction. Friction is one of the essentials when it comes to the physics of drifting. The amount of friction between the tires of a car and the surface depends on a lot of key factors. One factor is the surface and the condition of the surface. The amount of friction between the tires of the car and the surface can change because different surfaces have different patterns and different amounts of resistivity to sliding. On the reference table there is a difference in the coefficient of friction between asphalt and concre
