How you can exert a large force on an without doing any work?
You can exert a large force on an object without doing any work by exerting the force perpendicular to the direction of motion. In this case, no work is done because the force does not act in the direction of the object's displacement. This situation is commonly seen in scenarios involving static friction or when lifting an object vertically.
Explain - how you can exert a large force on an object without doing any work?
You can exert a large force on an object without doing any work by pushing against an immovable wall. In this scenario, although a large force is applied, no work is done because there is no displacement of the object in the direction of the force. Work is only done when there is both a force and displacement in the same direction.
What are the two forces involved when doing work?
The two forces involved when doing work are the applied force that you exert on an object, and the resistance force acting against the applied force, which is typically the force of gravity or another opposing force. Work is done when the applied force overcomes the resistance force to move an object.
What happens to the distance over which you exert your force?
The amount of force you exert remains the same, but the distance over which you exert the force can affect the work done. If you exert a force over a longer distance, you may do more work because the force acts over a greater distance. If the distance over which you exert the force is shorter, the work done may be less.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.

Explain how machines make work easier if they do not decrease the amount of work you need to do?
A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.
What happens to the distance over which you exert your force?
The amount of force you exert remains the same, but the distance over which you exert the force can affect the work done. If you exert a force over a longer distance, you may do more work because the force acts over a greater distance. If the distance over which you exert the force is shorter, the work done may be less.
3 ways simple machines make work easier?
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
How do machines make work easier?
A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or direction in which you exert your force.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
What is it when you exert force on an object that causes the object to move?
When you exert force on an object that causes it to move, it is called mechanical work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
Two examples of objects on which you exert forces when you are doing your schoolwork?
downward force of your body on the chair force on pen to write with
How is it possible to exert force but accomplish no work?
Hold a weight steady in your hand. Push a broken-down car that is stuck in the mud.
Does a machine make work easier by multiplying force you exert?
yes
