How work done against gravitational force?
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
What best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object
Why are you doing the same amount of work lifting a box or pushing it up a long ramp?
because the long ramp decreases the force you need to lift an object, but increases the distance you must move the object
Which statements best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object
What are the situations in which work is not done?
There are 3 conditions for work. First, there must be force. Second, when you apply a certain amount force to an object, it must move a certain distance. lastly, the force that you applied and the direction of the motion must be parallel. If you applied force tot eh right, then the object must move to the right. When you lift a book and then you walk around, no work is done. The direction of the force of your hand is going upwards while the direction of your motion is either left or right. Therefore the force applied and the distance moved are perpendicular.
To do work how must a force make an object move?
You apply a force to an object. The object must move in the same way as the applied force
What conditions must exist in order for a force to do work on an object?
The force must couple to the object. The point of application of the force must be able to move in the direction of the force.
What two things do you need to be able to know to measure work?
First you must know the amount of force used to move an object. And second, you must know the distance that the object moves
What is required for a force to work on an object?
The force must cause the object to move.
In order to have a contact force acting on an object the force must be?
they must be touching
What conditions must be met in order for work to be done?
1 there must be movement 2. there must be force 3. the force and satnce the object travels must be in the same direction
What is required for a force to do work on an object?
in the same direction as the object's motion.
