Newton's Second Law
01 · UNDERSTAND02 · RECALL03 · FEEDBACK04 · SPACED REVIEW
Before you attempt the question, read the concept and worked example. Then close the notes and answer from memory.
CORE IDEA
Force, mass, and acceleration connect through F = m × a. First find acceleration from the change in speed divided by time; then multiply by mass to find the net force.
WORKED EXAMPLE
A 1,200 kg car goes from 0 to 20 m/s in 10 seconds. Acceleration: (20 − 0) ÷ 10 = 2 m/s². Force: 1,200 × 2 = 2,400 N.
