Task 4 Video - Fundamentals of Force
- A short lesson on forces. This video describes a force, labels, motion, how to add and subtract force vectors.
- Go to this site, watch the video and take notes http://www.youtube.com/watch?v=lZ2kQzt6xOs
- You have made measurements of mass, length and time. These fundamental quantities are called scalar quantities because they possess magnitude, or size. Force is an example of a vector quantity as it has both magnitude and direction. Recall measurements that you have made that are either scalar or vector quantities. Hint: http://examples.yourdictionary.com/examples-vector-scalar-quantity-physics.html
- Write a definition of both terms scalar and vector.
- Make a table of examples of scalar and vector quantities.
