Understanding Momentum

Momentum is a measure of an object's mass in motion. It's calculated by:

* Momentum (p) = mass (m) × velocity (v)

Calculation

* mass (m) = 4 kg

* velocity (v) = 2 m/s

* Momentum (p) = 4 kg × 2 m/s = 8 kg m/s

Answer: The momentum of the 4 kg ball moving at 2 m/s is 8 kg m/s.
