Newton's Second Law and F = ma Practical

Spec 1.7

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).
