Answer :

For AP Physics 1, your calculator should typically be in 'degree mode.' This is because in physics, especially in mechanics, angles are usually measured in degrees. Using degree mode ensures that any trigonometric functions or calculations involving angles are computed correctly.

Here's how you can set your calculator to degree mode:

  1. Find the Mode Key: Look for the 'MODE' button on your calculator. This is usually near the top.

  2. Select Degree Mode: Press the 'MODE' button and scroll or navigate until you find the angle settings. You will likely see options like DEG (degree), RAD (radian), and possibly GRA (gradian). Choose 'DEG' or 'DEGREE."

  3. Confirm the Selection: Make sure to press the enter or execute button to confirm your selection.

It's important to have your calculator set correctly because many physics problems involve calculations with angles, such as resolving forces or projectile motion.

Remember, in some cases, your teacher or exam may have specific instructions about which mode to use, so always double-check when working with different problems or during an exam.
