Question

In any collision, an object experiences a force for a given amount of time that results in its mass undergoing a change in velocity. There are four quantities mentioned here: force, time, mass, and change in velocity. The force multiplied by the time (FX t) is known as the impulse and the mass multiplied by the velocity change (m X AV) is known as the change in momentum. The impulse experienced by an object is always equal to the change in its momentum. As a result: FXt = m X AV Mass does not change. Velocity decreases during a collision. Automobile manufacturers, such as Nissan and Toyota, incorporate safety features into their vehicles. Crumple zones in the engine compartment and air bags are two examples of safety technology designed to protect driver and passengers involved in a collision. How do these design features impact the formula above and the force of impact? They decrease the force of impact by providing a cushion during the impact.​

Answer 1

Crumple zones and airbags reduce the force of impact during a collision by increasing the collision time.

Step-by-step explanation:

In a collision, the force multiplied by the time is known as the impulse, while the mass multiplied by the velocity change is known as the change in momentum. The impulse experienced by an object is always equal to the change in its momentum. Safety features like crumple zones and airbags in cars reduce the force of impact by providing a cushion during a collision. They increase the collision time, which decreases the force acting on the car and its occupants.

Answer 2

How to calculate force?

.Inorder to calculate force we will use Newton's second law of motion.

`\\ \sf\longmapsto Force=Mass* Acceleration`

`\\ \sf\longmapsto F=ma`

Here we can observe

`\\ \sf\longmapsto F\propto a`

`\\ \sf\longmapsto F\propto m`
