Choose the correct answer:
1. A student wants to design an experiment to check whether a toy car moving along a straight path has uniform motion. She has a stopwatch and a measuring scale.
Which experimental plan should she choose?
Which experimental plan should she choose?
2. A student has recorded the following data for an object moving along a straight line:
First \(10\ s\) - \(8\ m\)
Second \(10\ s\) - \(8\ m\)
Third \(10\ s\) - \(8\ m\)
Fourth \(10\ s\)- \(12\ m\)
The student concludes that the object has uniform motion because the first three distances are equal.
What should you do to improve the student's conclusion?
