Impulse Calculator (J = Ft)
Determine the impulse applied to an object. This tool helps you solve for the impact force or the duration of contact based on the change in momentum.
J = F × Δt
If a 50 N force is applied for 0.1 seconds: J = 50 * 0.1 = 5 N·s.
What is impulse in physics?
Impulse (J) is the product of the average force (F) applied to an object and the time interval (Δt) during which it is applied. It represents the change in momentum of an object.
What is the formula for impulse?
The primary formula is J = F × Δt. Since impulse equals the change in momentum, it can also be expressed as J = Δp = m(v_final - v_initial).
What are the units of impulse?
The standard SI units for impulse are Newton-seconds (N·s) or kilogram-meters per second (kg·m/s). Both units are equivalent.
How does impulse relate to momentum?
The Impulse-Momentum Theorem states that the impulse applied to an object is exactly equal to the change in its momentum.
