How do you calculate impulse given force and time?

Impulse is calculated by multiplying the force applied by the time over which it is applied.

Impulse is a concept in physics that describes the change in momentum of an object when a force is applied over a period of time. It is represented by the formula Impulse = Force x Time. This means that if you know the force applied to an object and the time over which it is applied, you can calculate the impulse.

The unit of impulse is the Newton-second (Ns), which is equivalent to a kilogram meter per second (kg m/s). This is because force is measured in Newtons (N) and time in seconds (s).

To calculate impulse, you simply multiply the force by the time. For example, if a force of 10 Newtons is applied for 3 seconds, the impulse would be 30 Newton seconds (Ns). This means that the momentum of the object has changed by 30 kg m/s.

Remember, the force applied must be constant over the time period for this calculation to be accurate. If the force varies, you would need to calculate the average force over the time period.

In summary, impulse is a measure of the change in an object's momentum due to a force applied over a period of time. It can be calculated by multiplying the force applied by the time over which it is applied. This is a fundamental concept in physics and is crucial for understanding how objects move and interact.
