Newton's Second Law
F = ma = Δp/Δt
This formula belongs to the chapter "Force and Laws of Motion" in Class 9 Science. Use it after identifying the right variables, matching the chapter context, and writing the substitution clearly.
How to use it
- Identify the quantity you need to find.
- Check the related variables and units from the question.
- Substitute values carefully into the formula.
- Simplify step by step and write the final statement.
Worked cue
F=5kg×4m/s²=20N | If Δp=30 kg⋅m/s in 3s: F=10N
Rule note: F in Newtons, m in kg, a in m/s²
