Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless! William McDonough

We intuitively recognize that a force is a push or a pull. This intuitive understanding nearly describes the technical use of the word as well. If you apply a force to something, you mean that you change a state of rest into a state of motion, or vis versa, or that you change the state of motion.

An agent that acts to change a body’s motion is called a force. There is always a direction associated with a force, so force is a vector quantity. Newton’s First Law defines force by telling us it is the agent responsible for a change in the motion of an object.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
