Calculating Distance and Displacement along a Circular Path
1. Half the Circle
- When the body covers half the circle, it travels a distance equal to the circumference of half the circle.
- Distance = Circumference of half circle = π * radius = π * 14 cm ≈ 43.98 cm
- Displacement is the straight line distance between the initial and final positions.
- Displacement = Diameter of half circle = 2 * radius = 2 * 14 cm = 28 cm
2. One Fourth of the Circle
- When the body covers one-fourth of the circle, it travels a distance equal to the circumference of one-fourth of the circle.
- Distance = Circumference of one-fourth circle = π * radius / 2 = π * 14 cm / 2 ≈ 21.99 cm
- Displacement is the straight line distance between the initial and final positions.
- Displacement = Diameter of one-fourth circle = 2 * radius = 2 * 14 cm = 28 cm
3. Two Rounds of the Circle
- When the body covers two rounds of the circle, it travels a distance equal to the circumference of two circles.
- Distance = Circumference of two circles = 2 * π * radius = 2 * π * 14 cm ≈ 87.96 cm
- Displacement is the straight line distance between the initial and final positions, which will be zero as the body ends up at the starting point after completing two rounds.
In summary, when the body covers different fractions of the circular path, the distance traveled is calculated based on the circumference of the corresponding fraction, while the displacement is determined by the diameter of that fraction.
1. Half the Circle
- When the body covers half the circle, it travels a distance equal to the circumference of half the circle.
- Distance = Circumference of half circle = π * radius = π * 14 cm ≈ 43.98 cm
- Displacement is the straight line distance between the initial and final positions.
- Displacement = Diameter of half circle = 2 * radius = 2 * 14 cm = 28 cm
2. One Fourth of the Circle
- When the body covers one-fourth of the circle, it travels a distance equal to the circumference of one-fourth of the circle.
- Distance = Circumference of one-fourth circle = π * radius / 2 = π * 14 cm / 2 ≈ 21.99 cm
- Displacement is the straight line distance between the initial and final positions.
- Displacement = Diameter of one-fourth circle = 2 * radius = 2 * 14 cm = 28 cm
3. Two Rounds of the Circle
- When the body covers two rounds of the circle, it travels a distance equal to the circumference of two circles.
- Distance = Circumference of two circles = 2 * π * radius = 2 * π * 14 cm ≈ 87.96 cm
- Displacement is the straight line distance between the initial and final positions, which will be zero as the body ends up at the starting point after completing two rounds.
In summary, when the body covers different fractions of the circular path, the distance traveled is calculated based on the circumference of the corresponding fraction, while the displacement is determined by the diameter of that fraction.
