How to Calculate Impulse in Physics

What is impulse, and how is it calculated in physics?

In physics, impulse is defined as the change in momentum of an object. It is calculated by multiplying the mass of the object by the change in velocity it experiences.

Understanding Impulse in Physics

Impulse is a crucial concept in physics that helps us understand how the momentum of an object changes when a force is applied to it. When a force is exerted on an object for a certain period of time, it causes a change in the object's velocity, which in turn leads to a change in its momentum. This change in momentum is what we refer to as impulse.

Calculating Impulse

The formula to calculate impulse is:

Impulse (J) = mass (m) x change in velocity (Δv)

For example, if a car with a mass of 5kg experiences a change in velocity from -9m/s to 25m/s, the impulse can be calculated as follows:

J = 5 kg x (25 m/s - (-9 m/s))

J = 5 kg x 34 m/s

J = 170 kg m/s

Therefore, the impulse experienced by the car in this scenario is 170 kg m/s.
