Two cars accelerate at 2 m/sec2. Car A has a mass of 750 kg, while Car B has a mass of 1000 kg. What forces are required to accelerate each car? If you are concerned with the price of gas, which car would you rather drive and why?

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

You can decrease the resistance of a length of wire by

Ais a machine that makes work easier when a single force is applied. a simple machine b compound machine c endangered machine d complex machine
