# AP Physics

Subjects : science, ap, physics
Instructions:
• Answer 50 questions in 15 minutes.
• If you are not ready to take this test, you can study here.
• Match each statement with the correct term.
• Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. What is the general equation for motion down a slope and how does it change if the object is going up the slope?

2. What does the term potential difference mean?

3. Pressure of an open container at the opening.

4. S.I. unit of pressure
