• Work: $W=Fs$
• Power: �=��P=tW ​
• Kinetic Energy: ⿽�=12��2KE=21​mv2
• Gravitational Potential Energy: GPE=mgh

2. Electricity Formula:

• Ohm’s Law: $V=IR$
• Power in a Circuit: P = IV
• Resistance in Series: Total = 1 + 2 +… Rtotal​=R1​+R2​+…
• Resistance in Parallel: 1�total=1�1+1�2+… Rtotal​1​=R1​1​+R2​1​+…

3. Waves Formula:

• Wave Speed: ⿽=��v=fλ
• Frequency-Period Relationship: f=T1 ​
• Wavelength: �=��λ=fv ​

4. Light Formula:

• Snell’s Law: 1sin⁡(�1)=2sin⁡(�2) n1​sin(θ1​)=n2​sin(θ2​)
• Lens Formula: 1�=1�+1�f1​=u1​+v1​
• Magnification: �=�m=​

Tips for Creating Your Formula Sheet:

1. Organize Clearly: Group related formulas together under specific topics (e.g., mechanics, electricity) for easy navigation.
2. Include Units: Write down the units for each formula to reinforce your understanding and ensure proper application during the exam.
3. Highlight Key Formulas: Emphasize critical formulas that are frequently used or are fundamental to multiple topics.
4. Practice Using the Sheet: Familiarize yourself with the layout and content of your formula sheet during your revision to optimize its use in the exam.

How to Create a Formula in Google Sheets:

1. Select a cell: Click on the cell where you want the result of your formula.
2. Start the formula: Type an equal sign (=). This tells Google Sheets that you are about to enter a formula.
3. Enter the formula: For example, to add two numbers in cells A1 and B1, type=A1+B1. You can use operators like +, -, *, and / for addition, subtraction, multiplication, and division.
4. Press Enter: Press Enter on your keyboard, and the result of the formula will appear in the selected cell.

How to Copy a Formula in Google Sheets:

1. Select the cell with the formula: Click on the cell containing the formula.
2. Copy the Formula: Right-click on the cell, choose “Copy” from the context menu, or use the keyboard shortcut (Ctrl+C on Windows/Linux, Command+C on Mac).
3. Select the destination cells: Click on the cell or cells where you want to paste the formula.
4. Paste the Formula: Right-click on the destination cell, choose “Paste” from the context menu, or use the keyboard shortcut (Ctrl+V on Windows/Linux, Command+V on Mac).

How to Drag a Formula Down in Google Sheets:

1. Select the cell with the formula: Click on the bottom-right corner of the cell containing the formula. You’ll see a small square called the fill handle.
2. Drag Down: Click and drag the fill handle down to copy the formula to the desired number of cells.

How to Insert a Formula in Google Sheets:

1. Select a Cell: Click on the cell where you want to insert the formula.
2. Start the formula: Type an equal sign (=).
3. Enter the formula: Input the formula as needed.
4. Press Enter: Press Enter on your keyboard to apply the formula.

Conclusion:

Creating and using a formula sheet can be a powerful tool to enhance your performance in the GCSE Physics exam. It not only serves as a quick reference but also contributes to your overall understanding of the subject. Ensure that your formula sheet is well-organized, includes essential formulas, and becomes an integral part of your exam preparation strategy.
