The physics
Newton's second law is the working heart of classical mechanics: the net force acting on an object equals its mass multiplied by its acceleration.
Force to accelerate a 20 kg shopping trolley at 0.5 m/s²
Answer: force = 10 N (equivalent weight force 1.02 kgf).
What we know
- Mass: 20 kg
- Acceleration: 0.5 m/s²
Step by step
- Given
- m = 20 kg, a = 0.5 m/s²
- Formula
- F = m × a
- Substitute
- F = 20 × 0.5
- Result
- F = 10 N
All results
| Force | 10 N |
|---|---|
| Equivalent weight force | 1.02 kgf |
