[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Forces Have you ever wondered how forces link to our life? Everything we’ve learned in science has got me thinking about it. Forces are an essential part of our daily lives. Forces act on all objects. And we need force for everything we do‚ whether it’s a push‚ pull or twist. Force gives an object the energy to move‚ stop moving or change direction. Newton’s first law states that an objects velocity cannot change unless it is acted upon by a force. Here are examples of force in everyday life.

Health Field Model A model of the determinants of health proposed by Evans and Stoddart�the health field model�provides a broad conceptual framework for considering the factors that influence health in a community (Evans and Stoddart‚ 1990). Unlike a biomedical model that views health as the absence of disease‚ the field model includes functional capacity and well-being as health outcomes of interest (see Figure 1). The model also emphasizes general factors that affect many diseases or the health
