The physics
Momentum is 'quantity of motion': mass times velocity. It measures how hard something is to stop. A slow lorry and a fast bicycle can carry similar momentum — and require a similar impulse to bring to rest.
Momentum of an 80 kg runner at 5 m/s
Answer: momentum = 400 kg·m/s.
What we know
- Mass: 80 kg
- Velocity: 5 m/s
Step by step
- Given
- m = 80 kg, v = 5 m/s
- Formula
- p = m × v
- Substitute
- p = 80 × 5
- Result
- p = 400 kg·m/s
All results
