Answer 2

What is an impulse?

In physics, an impulse refers to the change in momentum of an object. It is a vector quantity that represents the product of the force applied to an object and the time interval over which the force is applied. The impulse experienced by an object is equal to the change in momentum it undergoes.

Formula for impulse

The formula for impulse is given by:

Impulse = Force × Time

Where: - Impulse is measured in units of Newton-seconds (N·s) or kilogram-meters per second (kg·m/s). - Force is measured in units of Newtons (N). - Time is measured in units of seconds (s).

Relationship between impulse and momentum

Impulse is closely related to momentum. In fact, impulse is defined as the change in momentum of an object. The relationship between impulse and momentum can be expressed by the equation:

Impulse = Change in Momentum

This equation shows that the impulse experienced by an object is equal to the change in its momentum.

Example of impulse calculation

Let's consider an example to illustrate the calculation of impulse. Suppose a tennis ball with a mass of 0.06 kg is struck by a racket with a force of 20 N for a duration of 0.02 seconds. To calculate the impulse experienced by the ball, we can use the formula:

Impulse = Force × Time

Substituting the given values into the formula, we get:

Impulse = 20 N × 0.02 s = 0.4 N·s

Therefore, the impulse experienced by the tennis ball is 0.4 N·s.

Conclusion

In summary, an impulse is the change in momentum of an object and is calculated by multiplying the force applied to the object by the time interval over which the force is applied. The impulse experienced by an object is equal to the change in its momentum.
