Which problem solving method should you use if you are given this problem: A car driving 32 m/s went 14 meters. How long were they driving?
basic math
cross multiplication
isolate the variable
none of the above
Which of the following is the correct scientific unit for speed/velocity?
meters/second*second
miles/hour
meters/second
none of the above
A constant speed means
A change in speed or direction results in a change in acceleration.
Going around a curve at a constant speed is a change in acceleration.
Slowing down is a change in acceleration.
All three of these are true.

Which of the following statements is true according to the Law of Conservation of Energy?
Energy cannot be created.
Energy can be converted from one form to another.
Energy cannot be destroyed.
All of the above
The second law of thermodynamics states:
Energy always flows from an area of high energy to low energy.
Energy always flows from an area of low energy to high energy.
Energy always flows from an area of low energy to high energy.
Energy can never be created or destroyed.
Assume there are two sleds. Sled A has twice the mass of Sled B. If both sleds have the same kinetic energy, which sled is moving faster?
Sled A because it has more mass
Sled B because it has less mass.
They are moving at the same speed because energy is not affected by mass.
There is not enough information.
Energy that is stored in the bonds of substances or chemicals is:
