Speed and Velocity

Speed:
- Definition: Distance travelled per unit time
- Scalar quantity
- No direction involved
- Formula:
  - speed = distance ÷ time
  - Symbolically: v = s / t
    where:
    - v = speed (m/s)
    - s = distance (m)
    - t = time (s)
Velocity:
- Definition: Change in displacement per unit time
- Vector quantity
- Direction matters (e.g. 20 m/s north)
- Formula:
  - velocity = displacement ÷ time
  - v = s / t (with vector understanding)

Question 1

Answer:
Explanation:

Question 2

Answer: Around 70-100 Words.
Explanation: The word limit is not mandatory. It may be more or less than this word count. However, 70 to 100 words per part (for example part a(i), part a(ii), part b(i), part b(ii)) provides enough to write the relevant content while not exceeding the given page space.

Keywords:

Speed and Average Speed Equations

- Instantaneous Speed:
  - Speed at a specific moment
  - Measured using short intervals or speedometers
- Average Speed:
  - Formula:
    - average speed = total distance travelled ÷ total time taken
  - Useful when speed changes over a journey
  - Example:
    - A car travels 150 km in 3 hours → Average speed = 150 ÷ 3 = 50 km/h

Answer:
Explanation:

Question 2

Keywords:

Acceleration and Deceleration

Acceleration:
- Definition: Change in velocity per unit time
- Vector quantity
- Units: m/s²
- Formula:
  - acceleration = (final velocity − initial velocity) ÷ time
  - a = Δv / Δt
    where:
    - a = acceleration (m/s²)
    - Δv = change in velocity (m/s)
    - Δt = time taken (s)
Deceleration:
- Negative acceleration
- Object is slowing down
- Same formula used (resulting a is negative)
Example Table:
u (m/s) v (m/s) t (s) a (m/s²)
0 20 4 (20 − 0)/4 = 5
30 10 2 (10 − 30)/2 = −10

u (m/s)	v (m/s)	t (s)	a (m/s²)
0	20	4	(20 − 0)/4 = 5
30	10	2	(10 − 30)/2 = −10

Question 1

Answer:
Explanation:

Question 2

Keywords:

Uniform and Non-Uniform Acceleration

Uniform Acceleration:
- Acceleration is constant
- Velocity changes by equal amounts in equal time intervals
- Example: Free fall (ignoring air resistance), a car speeding up steadily
Non-Uniform Acceleration:
- Acceleration varies over time
- Velocity changes by different amounts in same time intervals
- Example: A rollercoaster or car stuck in traffic

Curved line (steepening) Accelerating
Curved line (flattening) Decelerating

Graph Shape	Interpretation
Horizontal line	Object at rest
Straight line (constant gradient)	Constant speed
Curved line (steepening)	Accelerating
Curved line (flattening)	Decelerating

🔹 Speed–Time Graph

Features:
- Gradient = Acceleration
- Area under graph = Distance travelled
Interpretation:
Graph Shape Interpretation
Horizontal line Constant speed
Positive constant gradient Constant acceleration
Negative constant gradient Constant deceleration
Curve Changing acceleration
Line at 0 Object at rest

Graph Shape	Interpretation
Horizontal line	Constant speed
Positive constant gradient	Constant acceleration
Negative constant gradient	Constant deceleration
Curve	Changing acceleration
Line at 0	Object at rest

6. Acceleration Due to Gravity

Free Fall (g):
- All objects near Earth’s surface fall with constant acceleration if air resistance is ignored
- Symbol: g
- Value: 9.8 m/s² (or approx. 10 m/s² for estimates)
- Applies to objects in vertical free fall

Gradient and Area Calculations from Graphs

Speed from Distance–Time Graph

Speed = Gradient = rise ÷ run
Use coordinates to calculate:
Example:
- Point A (0 s, 0 m), Point B (4 s, 20 m)
- Speed = (20 − 0) ÷ (4 − 0) = 5 m/s

🔹 Acceleration from Speed–Time Graph

Acceleration = Gradient = Δv ÷ Δt
Example:
- v changes from 0 to 10 m/s in 5 s → a = 10 ÷ 5 = 2 m/s²

🔹 Distance from Speed–Time Graph

Distance = Area under the curve

Shape-based calculation:

Rectangle: Area = base × height
Triangle: Area = ½ × base × height
Trapezium: Area = ½ × (sum of parallel sides) × height

Example (constant acceleration):

v increases from 0 to 20 m/s in 4 s (triangle)
Distance = ½ × 4 × 20 = 40 m
