Key Topics and Sample Solutions from the Paper 1 Memo
Mechanics
Sample Question:
A car accelerates from rest to a speed of 20 m/s in 10 seconds. Calculate its acceleration.
Memo Solution:
- Use the formula for acceleration:
\( a = \frac{\Delta v}{\Delta t} \)
- \( \Delta v = 20\, \text{m/s} - 0\, \text{m/s} = 20\, \text{m/s} \)
- \( \Delta t = 10\, \text{s} \)
- \( a = \frac{20}{10} = 2\, \text{m/s}^2 \)
- Answer: 2 m/s²
Key Learning Point:
Understanding how to apply basic kinematic formulas is essential.
Properties of Matter
Sample Question:
Explain why objects with higher density tend to sink in water.
Memo Explanation:
- Density is mass per unit volume (\( \rho = \frac{m}{V} \)).
- An object sinks if its density is greater than that of water (about 1 g/cm³).
- Higher density means the object’s weight exceeds the buoyant force exerted by water.
- Conclusion: Objects with higher density than water sink because they are heavier relative to their volume.
Atomic Structure
Sample Question:
Describe the structure of an atom based on the Bohr model.
Memo Explanation:
- An atom consists of a nucleus containing protons and neutrons.
- Electrons orbit the nucleus in fixed energy levels or shells.
- The number of protons determines the element, while electrons determine chemical behavior.
- The Bohr model emphasizes quantized energy levels and circular orbits.
Chemical Reactions
Sample Question:
Balance the following chemical equation:
\[ \mathrm{Fe + O_2 \rightarrow Fe_2O_3} \]
Memo Solution:
- Count atoms on both sides:
Left: Fe = 1, O = 2
Right: Fe = 2, O = 3
- To balance Fe:
\( 2\, \mathrm{Fe} + O_2 \rightarrow Fe_2O_3 \)
- To balance O:
\( 4\, \mathrm{Fe} + 3\, O_2 \rightarrow 2\, Fe_2O_3 \)
- Final balanced equation:
\[ 4\, \mathrm{Fe} + 3\, O_2 \rightarrow 2\, Fe_2O_3 \]
Key Point:
Balancing chemical equations ensures conservation of mass.
