- Read the numerical-Take out the quantities given and quantity to be found out.Then find the formula to be used.
- In numerical of Motion-Work, Energy, Power and Sound, convert all the quantities in similar and preferably S.I. units.
- Show the complete steps in solving numerical.

- Never forget to write units of v, u, s, t and a etc.
- Always check the calculations of a numerical while rechecking the answer sheet.
- Don’t use short cuts in numerical.
- Don’t miss to write the key terms in answers.

- Learn the equations and formulae by writing again and again.
- Check the numerical/calculations again before submitting the answer sheet.
- Learn the valences and make the formula for required compounds yourself.

- Never write unbalanced equations.
- Never try to mug-up all the formulae. Formulae and series should be learnt by heart and preferably by linking them by a story. For example reactivity series can be learnt like this.

**Q1.What are the formulas in science?**

**Ans. **In science, a formula is a succinct way of expressing information symbolically, for example in a mathematical or chemical formula. The informal use of the term formula in science refers to the general construction of the relationship between given quantities. Formulas used in science almost always require a selection of units. Formulas are utilized in physics to precise relationships between different quantities, like temperature, mass, or charge.

**Q2. How to remember science formulas?**

**Ans.** To remember science formulas one can use the following tips.

1. Use and write formulas first when solving related questions.

2. Call up formulas regularly and visualize them.

3. Learn mnemonic and apply creative memory links to memorize long-term formulas.

4. In 2 to 3 weeks, take a test with formulas and write down all the formulas.

5. Make it more interesting and with the help of a like-minded friend, play a game by asking for formulas at random and the winner can throw a party.

6. Understand the logic behind the formula and learn how the formula is derived.

**Q3. How to learn science formulas?**

**Ans.** Understand chapter before revising the science formulas to learn chapter wise science formulas one must have very clear idea about the chapter. Chapter wise science formulas consist of all-important points of the chapter. Do follow the following tips and suggestion to learn formulas easily.

1. Relax your brain and concentrate on science formulas.

2. Practice as much as you can.

3. List all the important formulas on a sheet of paper for practice.

4. Try to clarify your basic concepts before proceeding with the formulas. This will help you understand the meaning of the formula.

5. Keep away with all distractions and learn the derivation of every formula.

**Q4. Is it necessary to know how does science formulas work?**

**Ans. **Indeed, it is necessary to understand and solve equations either when you want to work as a scientist or in another field that uses science, or when you want to become a science teacher or a teacher in an area that uses science.

**Q5. Why it is important to learn science formulas?**

**Ans. **It is important to learn and understand the scientific formulas according to your curriculum. With the help of these formulas, you can solve any problem with ease. Also, if you plan to become a scientist in the future, or be associated with this field, in particular, it is extremely important to learn all the formulas effectively.
