What equation summarizes Newton's second law?

Force equals mass times acceleration, written F = ma.

Start playing free

  1. F = m divided by a
  2. F = ma ✔
  3. F = m plus a

Why: Acceleration depends on both applied force and mass. With the same mass, more force produces more acceleration.

Huh, didn't know that: The same force accelerates a lighter object more than a heavier one.

The dad joke
Force and mass multiplied their efforts and got acceleration.

Answer: F = ma. Acceleration depends on both applied force and mass. With the same mass, more force produces more acceleration.
