    Force
In summary, the force applied to a wood fence by a person weighing 175lbs running into it at 7km/per hour cannot be determined without additional information. Similarly, the force applied to an abandoned car on train tracks by a TGV train weighing 415 tons traveling at 574km/per hour or a freight train weighing 10,000 tons traveling at 50km/per hour cannot be determined without more specific details about the collision.

1. For example. If you weigh 175lbs and you were

running into a wood fence at 7km/per hour how much

force is being applied the Wood fence?

Another Example. the TGV Train in France reached its

highest speed at 574km/per hour it weighs 415tons,

if this train were to collide with an abandon car on

the tracks how much force would be applied to the

abandon car on the tracks if the train were going

570km/per Hour and the Train weighs 415tons

(914,918lbs).

another example: A freight Train weighing 10,000

tons going at a speed of 50km/per hour were to hit

an abandon car how much force is being applied to

the car on the tracks?

The distance of the Fence is 40ft.

The distance of the Car is 100ft.

The force applied depends on the details of the collision. Given an impact velocity and masses, you can't find the force associated with a collision solely from that info.
 

FAQ: Calculating Force of Impacts on Objects

1. What is the formula for calculating force of impacts on objects?

The formula for calculating force of impacts on objects is force = mass x acceleration, or F = ma.

2. How do you determine the mass of an object?

The mass of an object can be determined by using a scale or balance to measure its weight, which is a measurement of the force of gravity acting on an object.

3. How do you measure acceleration?

Acceleration can be measured by calculating the change in an object's velocity over time. This can be done using a variety of tools such as a speedometer, accelerometer, or by tracking an object's movement using video analysis.

4. Can the force of an impact be negative?

Yes, the force of an impact can be negative if the object experiences a deceleration or change in velocity in the opposite direction of its initial motion. This is often referred to as a "negative impact" or "negative force."

5. How does the angle of impact affect the force on an object?

The angle of impact can affect the force on an object by changing the direction and magnitude of the force. For example, if an object is impacted at a 90-degree angle, the force will be greatest and directly perpendicular to the surface. However, if the angle is less than 90 degrees, the force will be lessened and may also have a horizontal component, causing the object to be pushed or pulled in a certain direction.
