# How does safety-technology change momentum?

I need to find out the question "How does safety-technology change momentum?" ASAP (As soon as possible)

### How do you find change in momentum over time given constant velocity?

Momentum = (mass) x (velocity vector). Given constant velocity, and assuming that mass doesn't change, there is no change in momentum over time. If there is any change in momentum, it can only be due to a change in mass. It would change in direct proportion to the mass, and the direction of the momentum vector would remain constant, in the direction of the velocity.

### What is the inertia of motion?

Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.

### What is the Law of convesation of momentum?

It means that the total momentum of a closed system doesn't change over time. The total momentum is obtained by adding the momentum of each individual object or particle. It means that the total momentum of a closed system doesn't change over time. The total momentum is obtained by adding the momentum of each individual object or particle. It means that the total momentum of a closed system doesn't change over time. The total momentum…

### What is the law of conversation of momentum?

That means that a quantity, called "momentum", can be defined, and that this quantity does not change over time. In any collision, for example, the momentum (which is defined as mass x velocity) of individual objects can change, but the total momentum does not change. Please note that since velocity is a vector quantity, momentum is also a vector quantity.

### What is the formula for instantaneous impulse?

The definition of impulse is change in momentum, how is there CHANGE in an instant? Or you are asking the instantaneous MOMENTUM, then it's the mass of the object times its speed. Or you are asking the CHANGE in momentum, impulse, after a specific time. If the average force applied to the mass is given, it's force times change in time. If a change in Force is observed, you have to integrate. If there is…

### What happens to momentum 2 objects collide?

In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have…

### What is Change in momentum times time?

Impulse = [(change in momentum)/time]*time [(change in momentum)/time] = Force And when force acts for a period of time, that impulse changes the momentum of the object. You can also rewrite the impulse equation as: I = F*t However, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m. These units are not in common usage.
