Impulse:
If a Force F is applied for a small time interval t, then the product of F and t is known as Impulse.
Numerically, Impulse is equal to change in momentum.
F × t = m (v – u)
where v = velocity after the impact, u = velocity before the impact, t = fraction of time during which force is applied
Calculation:
Given:
F = 50 N, t = 10 ms = 10 × 10-3 s, u = 0 and m = 0.5 kg
F × t = m (v – u)
50 × 10 × 10-3 = 0.5 × (v – 0)
∴ v = 1 m/sLast updated on May 19, 2025
