I have to write questions for our California Standards for Physics, like we're making our own 50-question test.
Standard 1a: Students know how to solve problems that involve constant speed and average speed.
Two questions: do you think this standard needs two questions, or one? And if it needs two questions, what question could I possibly write down for constant speed?
Using a ramp of length 2m, you apply a 150N force to move a 20kg object a vertical distance of 1m. How much work does gravity do on the object?
