I have the flu :-( Justin and Ian, tomorrow you need to test your bridge, ok?
===
We are now moving from vectors and static forces (which don't move, or move at a constant velocity) to unbalanced forces (which have a lot more math, so you are going to need a calculator).
Today, you will study Hooke's law, which talked about movement of objects using potential and kinetic energy.
You can find the online simulation here
When you are finished, EACH person needs to post and individual paragraph in the comments section of the blog. Tell me about the difference between the forces and vectors that lead to kinetic energy, potential spring energy and potential gravitational energy.
Test is THURSDAY.
Congratualations to the football gentlemen for a TREMENDOUS EFFORT last night and good luck to the volleyball team tonight!

Force is the amount of energy while vectors are which directions the forces are acting on. Potential spring energy is the energy applied to the spring, allowing it to use the energy to stretch. Potential gravitational energy is the energy an object possesses because of its position in a gravitational field.
Kinetic energy is energy of motion. The more motion a vector has, the more kinetic energy there is. Gravitational potential energy depends on the mass and the height. When the spring has a lot of mass on it and is stretched far, the gravitational potential energy is greater. Potential spring energy is the stored energy of a spring. The amount of potential energy depends on the compression or stretching of the spring. If the string is not stretched or compressed, it does not have any potential energy.
Vectors show which direction the force is applying energy
force is how much energy
potential spring energy is energy applied to the string
gravitational energy is determined by the position of the object compared to the gravittaional field...energy applied to the spring becomes spring energy..vectors are determined by direction of the force applied and force is energy
Vectors have motion or kinetic energy. The amount of gravitational potential energy depends on the mass of the object and how much friction is acting upon the object.
kinetic energy is the motion of an object. Gravitational pull is the force acted upon the spring. Potential spring energy is the amount of energy on the spring. if it is not compressed then there is no potential energy.
kinetic energy is energy of the motion of an object. Force is the amount of energy while vectors are directions the forces are acting on.The more motion a vector has, the more kinetic energy an object has. Potential spring energy is the stored energy in a spring. If the spring is stretched or compressed, it does not have any potential energy.
