Investigating Forces

Science · Forces & Motion · procedural

Plan and carry out investigations into forces, including measuring force with a newton meter, investigating Hooke's Law, and collecting and interpreting motion data to test Newton's laws

What mastery looks like

  • Uses a newton meter correctly to measure forces in newtons
  • Sets up and conducts a Hooke's Law investigation, recording force and extension and plotting a graph
  • Identifies and controls variables in a force investigation
  • Calculates acceleration from force and mass data and compares with experimental results

Check your understanding

If Investigating Forces set up an experiment hanging weights on a spring and measuring how much it stretched, could they describe how they would make it a fair test, record the results, and show what Hooke's Law looks like on a graph?
