What you need to know
- State Newton's second law
- Explain how force and mass affect acceleration
- Describe the experiment that tests it
Active recall
Quick check
Answer each question before opening the answer.
State Newton's second law as an equation.
Resultant force = mass × acceleration (F = m × a).
If the resultant force doubles and mass stays the same, what happens to acceleration?
The acceleration also doubles (they are directly proportional).
