What else can I help you with?
What can happen from swallowing a sharp object?
It can lacerate (cut) and get lodged in your esophagus and if it manages to work it's way down to your stomach it can do a lot of damage there. If you have swallowed a sharp object go to ER immediately!
How do knives work to cut through objects?
Knives work to cut through objects by applying force to a small area, creating enough pressure to separate the molecules of the object being cut. The sharp edge of the knife concentrates this force, making it easier to slice through materials.
What is the product of the force on an object and the distance through which the object is moved?
work
Can a body or object do work?
Yes it can! In physics work is the number of joules per second that the object or body (assuming large planetary body) uses or emmits per second, work is measured in Watts and it is usually electromagnetic radiation that carries this energy.
What is the result of a force moving an object through a distance called?
The result of a force moving an object through a distance is called work. Work is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force.
When work is being done an object is being what?
Moved. Work is defined as a force acting on an object through a distance.
What is performed when a force moves an object through a distance?
Work is performed when a force moves an object through a distance. Work is calculated by multiplying the force applied by the distance over which the object moves in the direction of the force. The unit for work is the joule (J).
How does a knife work to cut through objects?
A knife works to cut through objects by applying force to a small area, creating enough pressure to separate the molecules of the object being cut. The sharp edge of the knife concentrates this force, making it easier to slice through materials.
Why a force acting on an object does no work if the object is not in motion?
Work is defined as the product of force and displacement. If an object is not in motion, there is no displacement, thus no work is done by the force acting on the object. Work is only done when a force causes an object to move through a distance in the direction of the force.
What is the use of force to move an object through a distance?
work
What has to happen in order for work to be done on an object?
Work is done on an object when a force is applied to move the object through a distance in the direction of the force. The amount of work done is equal to the force applied times the distance the object moves.
How force and energy are related?
Force is the interaction that causes an object to accelerate, while energy is the capacity to do work. When a force acts on an object and causes it to move, work is done and energy is transferred. In this way, force can change the energy of an object by doing work on it.
