Linear Impulse Calculator:
Enter the values of total linear force, LF(N) and change in time, dt(s) to determine the value of Linear impulse, JL(N-s).
Linear Impulse Formula:
Linear impulse (JL) signifies the change in linear momentum of an object when a force is applied over a specific period. It is a vector quantity, measured in newton-seconds (N·s), and reflects the overall effect of a force acting over time on an object.
A larger force applied in the same amount of time (dt) results in a greater impulse, transferring more momentum to the object and potentially causing a significant change in its velocity.
Even a small force applied for a longer duration (dt) can deliver a significant impulse compared to a larger force applied for a shorter time.
A force (F) acts on an object for a short time interval (dt). This force application transfers momentum to the object.
The linear impulse quantifies the total momentum transferred, considering both the force magnitude (F) and the duration (dt) of its application.
Linear impulse can be calculated as the product of the average linear force applied and the time duration over which the force is applied.
Linear impulse, JL(N-s) in Newton second is calculated by the product of total linear force, LF(N) in Newton and change in time, dt(s) in seconds.
Linear impulse, JL(N-s) = LF(N) * dt(s)
JL(N-s) = linear impulse in Newton second, N-s.
LF(N) = linear force in Newton, N.
dt(s) = change in time in seconds, s.
Linear Impulse Calculation:
- Finding Linear Impulse (JL) using Force and Time Interval:
Given: LF(N) = 10N, dt(s) = 3s.
Linear impulse, JL(N-s) = LF(N) * dt(s)
JL(N-s) = 10 * 3
JL(N-s) = 30N-s.
- Finding Time Interval (Δt) using Linear Impulse and Force:
Given: LF(N) = 25N, JL(N-s) = 50N-s.
Linear impulse, JL(N-s) = LF(N) * dt(s)
dt(s) = JL(N-s) / LF(N)
dt(s) = 50 / 25
dt(s) = 2s.
