Physics Name: Worksheet ‐ Combining & Resolving Forces COMBINING FORCES Remember that force is a vector quantity. This means that when more than one force act concurrently on an object then the resultant (net) force can be found by adding the vectors head to tail.

Feb 23, 2024 · Worked example. Calculate the magnitude and direction of the resultant force in the diagram below. Step 1: Add up all of the forces directed to the right. 4 N + 8 N = 12 N. Step 2: Subtract the forces on the right from the forces on the left. 14 N – 12 N = 2 N. Step 3: Evaluate the direction of the resultant force.
5. Re-arranging Equations. 5. Re-arranging Equations Step Up to GCSE Physics. Many equations in Physics involve three quantities. On these pages, we practise re-arranging equations so that we can calculate what we need. Let’s use the equation A= b×c, usually written A = bc. If b = 2 and c =5, then A = b×c = 2×5= 10. We can get c = 5 from 5 ...
