2) Momentum changes when a net force is applied. if momentum chnges, forces are created; if momentum changes quickly, large forces are involved. The relationship between the force and motion follows directly from the second law(a= Fnet/m). Acceleration is the change in speed divided by the change in time. To find the force you have to translate the acceleration into "change in velocity divided by the change in time" and then times mass, basically like this- F= m*delta v/ delta t ( force= mass* change in velocity/ change in time). In momentum form of the second law it's the same thing, but little bit different. Mass multiplied by the change in velocity equals the change in momentum, so we can rewrite the equation that shows force is equal to the rate of change in momentum like this- F= delta p/ delta t (force= change in momentum/ change in time)
Jessica and Zuheidy Yes your project is due Tuesday and I am so glad it is muy bien y muy bonito. The Physics challenge posted here should be posted on the blog. Have a good night.

Do we have to put the response to the physics challenge up on the blog or do we just write it in our notebook?

Hi Ms. O'Neill, our project is due Tuesday, right?
P.S. Our project is coming out muy bien & muy bonito.

Jeena,
your explaination is Ok but does not actually explain about the unit of measure a force. Please see me about your response.
