In this lesson, we will learn how to change the subject of a formula and recognise valid rearrangements of combinations of formulas.
Students will be able to
Q1:
One side of the formula 𝑣=𝑢+2𝑎𝑠 is 𝑣. The formula is rearranged so that one side of the formula is equal to (𝑣−𝑢)2𝑠. Which of the following is the other side of the formula equal to?
Q2:
Kinetic energy is given by the formula 𝐸=12𝑚𝑣. The weight, 𝑊, of an object is 𝑚𝑔. Which of the following is a correct formula that has a subject equal to the ratio of the kinetic energy of an object to its weight?
Q3:
The subject of the formula force = mass × acceleration is force. Which of the following correctly shows the same formula with acceleration as the subject of the formula?
