The centrifugal force equation, Fc = (m × v2) ÷ r, calculates the outward force experienced by an object moving in a curved path. In this equation, Fc represents the centrifugal force, m is the mass of the object, v denotes the velocity of the object, and r signifies the radius of the curved path.
Practice problems
Problem #1
Determine the centrifugal force acting on a scooter weighing 80 kg as it moves in a circular path with a radius of 16 m and a velocity of 2 m/s.
Solution
Given data:
- Centrifugal force acting on a scooter, Fc = ?
- Mass of a scooter, m = 80 kg
- Radius of a circular path, r = 16 m
- Velocity of a scooter, v = 2 m/s
Applying the formula:
- Fc = (m × v2) ÷ r
- Fc = [80 × (2)2] ÷ 16
- Fc = 320 ÷ 16
- Fc = 20 N
Therefore, the centrifugal force acting on a scooter is 20 N.
Problem #2
Calculate the centrifugal force acting on a bike weighing 150 kg, which moves with a velocity of 1 km/h in a circular path of radius 5 m.
Solution
Given data:
- Centrifugal force acting on a bike, Fc = ?
- Mass of a bike, m = 150 kg
- Velocity of a bike, v = 1 km/h = 0.27 m/s
- Radius of a circular path, r = 5 m
Applying the formula:
- Fc = (m × v2) ÷ r
- Fc = [150 × (0.27)2] ÷ 5
- Fc = 10.935 ÷ 5
- Fc = 2.18 N
Therefore, the centrifugal force acting on a bike is 2.18 N.
Problem #3
Find the centrifugal force acting on a girl weighing 24 kg who is enjoying a carousel ride. The girl sits on a carousel rotating in a circular path with a radius of 8 m and a velocity of 1 m/s.
Solution
Given data:
- Centrifugal force acting on a girl, Fc = ?
- Mass of a girl, m = 24 kg
- Radius of a circular path, r = 8 m
- Velocity of a girl, v = 1 m/s
Applying the formula:
- Fc = (m × v2) ÷ r
- Fc = [24 × (1)2] ÷ 8
- Fc = 24 ÷ 8
- Fc = 3 N
Therefore, the centrifugal force acting on a girl is 3 N.
Problem #4
Determine the centrifugal force acting on a bus weighing 700 kg as it moves in a circular path with a velocity of 0.8 km/h. The radius of the circular path is 8 m.
Solution
Given data:
- Centrifugal force acting on a bus, Fc = ?
- Mass of a bus, m = 700 kg
- Velocity of a bus, v = 0.8 km/h = 0.22 m/s
- Radius of a circular path, r = 8 m
Applying the formula:
- Fc = (m × v2) ÷ r
- Fc = [700 × (0.22)2] ÷ 8
- Fc = 33.88 ÷ 8
- Fc = 4.23 N
Therefore, the centrifugal force acting on a bus is 4.23 N.
