Question: When The Force Of Impact Is Extended Over A Longer Period Of Time?

How do you calculate the force of impact?

F = m * v² / (2 * d) ,F is the average impact force,m is the mass of an object,v is the initial speed of an object,d is the distance traveled during collision.Dec 2, 2020.

What are the four main effects of force?

(a) a stationary object to move, (b) a moving object to change its speed, (c) a moving object to change its direction of motion, (d) an object to change in size and shape.

Which object has the greatest acceleration?

Object C has the greatest acceleration. It is the only object with an acceleration. Accelerated motion on a p-t graph is represented by a curved line.

How does impact time affect force?

If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. … Automobiles are made to collapse upon impact, extending the time of collision and lessening the impact force.

What are the impact of force?

A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.

How can the force of impact be reduced?

Minimizing Impact ForceIf you jump to the ground from any height, you bend your knees upon impact, extending the time of collision and lessening the impact force.A boxer moves away from a punch, extending the time of impact and lessening the force.More items…

What are 3 factors that determine force of impact?

Speed, weight, and time between impact and stopping all affect force of impact.

What is the force of a bullet impact?

So essentially a bullet carries a kinetic energy potential measured in the Foot/LBs in the English metric. A . 50 BMG machine gun fires a 650 gr projectile at around 3000 fps. This translates to roughly 16000 pound of force at the muzzle.

When the force of impact on an object is extended in time does the impulse increase or decrease?

Physics the fourthABWhen the force of impact on an object is extended in time, does the impulse increase or decrease?IncreasesDistinguish between impulses and momentum.Which is force x time and which is inertia in motion?Impulse=force x time;momentum is inertia in motion.26 more rows

Which has more momentum a very fast baseball or a very slow bowling ball?

Yes, a fast baseball could possess the same momentum as a slow bowling ball. No, the bowling ball will have a greater momentum because its acceleration will always be less than the baseball. No, the bowling ball is much more massive so it will always have a larger momentum.

What is the force applied over a period of time?

In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts.

How does an increased length of time that a force acts on an object affect the strength of the impulse produced?

How does an increased length of time that a force acts on an object affect the strength of the impulse produced? The first force is the larger force because impulse is equal to the product of force and time. … Two forces produce equal impulses, but the second forces acts for a time twice that of the first force.
