Simple impulse force question - force upon impact

In summary, the conversation discusses the possibility of calculating the impulse force F in a collision when the time of collision is unknown. The only known formula to calculate this force is F*Δt = m*Δv, but the individual is wondering if there are other formulas that involve plasticity or the distance an object moves after a collision. It is concluded that these variables cannot be used to calculate the force, as the only measurable variables in a collision are distance, time, and mass. However, it is mentioned that if an object collides with a surface and takes time T to stop, the average force exerted on it can be calculated using the formula f= ma= mv/T.

Is there a way to calculate the impulse force F if the time of collision is unknown? The only formula I know to calculate this force is F*Δt = m*Δv. Is there a formula that perhaps uses plasticity as a variable instead of time or maybe uses the distance an object moves after a collision? Any help would be greatly appreciated. This is for an engineering project.

I think no. Because the only measurable variables on a colision is the distance, time and mass. The another things are calculated with that.

You can certainly say that if an object of mass m, with velocity v, collides with a surface and takes time T to stop, then it had average acceleration a= v/T. The (average) force exerted on it by the surface (and so the force it exerts on the surface) is given by f= ma= mv/T.
 

1. What is a simple impulse force?

A simple impulse force is a sudden and brief force that acts on an object upon impact.

2. How is simple impulse force calculated?

Simple impulse force is calculated by multiplying the change in momentum of an object by the time interval in which the impact occurs.

3. What factors affect the magnitude of a simple impulse force?

The magnitude of a simple impulse force is affected by the mass and velocity of the object, as well as the duration of the impact.

4. How does a simple impulse force differ from a continuous force?

A simple impulse force is a one-time, short-lived force that occurs upon impact, while a continuous force is applied over a longer period of time.

5. What are some common examples of simple impulse forces?

Some common examples of simple impulse forces include throwing a ball, hitting a ball with a bat, and a collision between two objects.
