Hour to Seconds

$$1 h = 3600 s$$

Description: Hour to Seconds is a standard relation used in measurement-and-motion.

Example:

Apply the relation: 1 h = 3600 s

Identify the known values, substitute them in the relation, and solve for the unknown quantity.
Result depends on the substituted values.

Applications:

  • Use this when the quantities in the relation are known and the missing quantity is required.

Kilogram to Gram

$$1 kg = 1000 g$$

Description: Kilogram to Gram is a standard relation used in measurement-and-motion.

Example:

Apply the relation: 1 kg = 1000 g

Identify the known values, substitute them in the relation, and solve for the unknown quantity.
Result depends on the substituted values.

Applications:

  • Use this when the quantities in the relation are known and the missing quantity is required.

Metre to Centimetre

$$1 m = 100 cm$$

Description: Metre to Centimetre is a standard relation used in measurement-and-motion.

Example:

Apply the relation: 1 m = 100 cm

Identify the known values, substitute them in the relation, and solve for the unknown quantity.
Result depends on the substituted values.

Applications:

  • Use this when the quantities in the relation are known and the missing quantity is required.

Speed

$$speed = distance / time$$

Description: Speed is a standard relation used in measurement-and-motion.

Variables:

  • distance = path length
  • time = duration

Example:

Apply the relation: speed = distance / time

Identify the known values, substitute them in the relation, and solve for the unknown quantity.
Result depends on the substituted values.

Applications:

  • Use this when the quantities in the relation are known and the missing quantity is required.

💡 Worked Examples

Step-by-step solutions using Measurement And Motion formulas

Example 1: Area of Circle

Circle Area Formula
Problem:

Find the area of a circle with radius 7 cm.

Solution:
  1. Given: r = 7 cm
  2. Apply formula: A = πr²
  3. Substitute: A = π × 7²
  4. Calculate: A = π × 49 = 49π cm²
  5. Approximate: A ≈ 49 × 3.14159 ≈ 153.94 cm²
Answer:

Area = 49π cm² ≈ 153.94 cm²

Practice Problems

Check Your Formula Recall

Write each formula once, define every variable, then solve one direct substitution problem before moving to mixed questions.

Apply Measurement And Motion

Pick two formulas from this page and create your own values for the variables. Verify units and signs before calculating.

Derivation Notes

Focus on how the formula is built, not only the final expression. Derivations help with board-exam reasoning and multi-step application questions.

  • Start from the definition or identity used in the chapter.
  • Write assumptions clearly before substituting values.
  • Track units through each step to catch calculation mistakes.
