Examples:💡

Example 1: Calculating the force required to move an object.

Solution:

Step 1: Identify the mass of the object and the acceleration required.

\[ F = m \cdot a \]

Step 2: If the mass of the object is 10 kg and the acceleration is 2 m/s², calculate the force.

\[ F = 10 \cdot 2 = 20 \text{ N} \]

Example 2: Determining the energy consumption of an electrical device.

Solution:

Step 1: Identify the power rating of the device and the time it is used.

\[ E = P \cdot t \]

Step 2: If a device has a power rating of 100 W and is used for 3 hours, calculate the energy consumed.

\[ E = 100 \cdot 3 = 300 \text{ Wh} \]

Common Mistakes

  • Mistake: Confusing mass and weight; mass is a measure of matter, while weight is the force due to gravity.

    Correction: Always remember that weight is calculated as W = m * g, where g is the acceleration due to gravity.

  • Mistake: Misapplying formulas; students often forget to check units or apply the wrong formula for the situation.

    Correction: Always verify the context of the problem and ensure the correct formula is used with appropriate units.
