•Define momentum in your own words: Momentum is the "strength" that a moving object has. It depends on how heavy the object is and how fast it's going.

•What is an impulsive force? It is a high-magnitude force that acts over a very short time interval, like a bat hitting a ball or a car hitting a wall.

•Why can we neglect other forces during impact? During a collision, the impulsive force is so massive compared to forces like friction or gravity that those smaller forces don't significantly change the outcome in that split second.

•What changes when stopping time increases? When you increase the time it takes to stop, the average impact force decreases.

•Why do airbags reduce injuries? Airbags extend the time it takes for your body to come to a stop. Because the change in momentum happens over a longer period, the force applied to your body is much lower.

DEFINE MOMENTUM IN YOUR OWN WORDS: Momentum is how much motion an object has. It depends on mass and velocity. The heavier or faster something is, the harder it is to stop.

WHAT IS AN IMPULSIVE FORCE? An impulsive force is a very large force that acts over a very short time during a collision.

WHY CAN WE NEGLECT OTHER FORCES DURING IMPACTS? Because the collision happens in a very short time. The impact force is much bigger than forces like gravity in that moment

WHAT CHANGES WHEN STOPPING TIME INCREASES? If stopping time increases, the peak force decreases. The object slows down more gradually.

WHY DO AIRBAGS REDUCE INJURIES? Airbags increase stopping time and stopping distance. This reduces the peak force on the body, which lowers injury risk.

Define momentum in your own words: momentum is the amount of motion an object has. It depends on how heavy it is (mass) and how fast is moving (velocity).

What is an impulsive force? An impulsive force is a very large force that acts for a very short time, usually during collision.

Why can we neglect other forces during impact? During a collision, the impact force is much larger than forces like gravity or friction.

What changes when stopping time increases? If stopping time increases: -The deceleration decreases; -The force decreases. The change in momentum is the some, but spreading it over a longer time reduces the forces.

Why do airbags reduce injuries? They reduces injuries because they: increase the stopping time of the person, reduce the force acting on the boox and spread the force over a larger area.

Define momentum in your own words.
Momentum is the quantity of motion an object has; it depends on its mass and velocity. The heavier and faster an object is, the greater its momentum.

What is an impulsive force?
An impulsive force is a very large force that acts over a very short period of time, such as during a collision.

Why can we neglect other forces during impact?
During an impact, the impulsive force is much greater than other forces like gravity or friction, so their effect is negligible.

What changes when stopping time increases?
When stopping time increases, the average force decreases because the same change in momentum happens over a longer time.

Why do airbags reduce injuries?
Airbags increase stopping time and stopping distance, which reduces the peak force on the body and lowers the risk of injury.

-Define momentum in your own words:

momentum is the quantity of motion an object has.It depends on its mass and velocity.The heavier or faster an object is, the greater its momentum.

-What is an impulsive force?

An impulsive force is a very large force that acts in a very short time, like during a crash or collision.

-Why can we neglect other forces during an impact?

Because during an impact the collision force is much greater than other forces, so it's the most important one affecting motion.

-What changes when stopping time increases?

When stopping time increases, the force decreases.

-Why do airbags reduce injuries?

Airbags increase the stopping time during a crash, this reduces the force on the body and lowers the risk of injury.

1. DEFINE MOMENTUM IN YOUR OWN WORDS:

Momentum is the force necessary to bring an abject from a point A to a point B at a determinate speed.

2. WHAT IS AN IMPULSIVE FORCE?

An impulsive force is a force that act on a body for a short period of time and its generated, most of the time, by an impact.

3. WHY CAN WE NEGLECT OTHER FORCES DURING IMPACT?

Because the only forces that matters during an impact are the impulsive forces and those ones ignore the effects of the other forces.

4. WHAT CHANGES WHEN STOPPNG TIME INCREASES?

The momentum and the peak force

5. WHY DO AIRBGS REDUCE INJURIES?

Beacuse they change the momentum of the impact by lengthening it, this reduces peak force intensity and the stress on the body reduces significatly
