Explanation / Answer

1- A mass is accelerating when it is seen doing what? Changing its velocity or speed. Accelerationis the rate of change of velocity with respect totime. 2- Now that we know the newton's law, what can beinfered about mass which is accelerating? Newton's law states that Force equal masstimes acceleration or F=ma. Since a mass is accelerating itinherently is being acted upon by a force of equal and oppositemagnitude. 3- How can you explain why your car stops quicker when tirescontinue rotating during braking? If the composition of the roads surface isas such that the tires are not making direct contact with it. akathere's dirt/snow/water on the road, then they make greater contactwith the road when they are rolling because when they skid, theyare accumulating materials under them which has less friction thenthe road. Also, when your tires roll, the very bottom of them hasno velocity while the rest of the tire has velocity; when theyskid, the whole tire has velocity. Since static friction is greaterthan kinetic friction, it is better to keep the tirerolling. b: what causes this method to be more effectivethan when your tire skid during braking? When your tires roll, the very bottom ofthem has no velocity while the rest of the tire has velocity; whenthey skid, the whole tire has velocity. Since static friction isgreater than kinetic friction, it is better to keep the tirerolling.
