In summary, exerted force is the physical effort or energy applied to an object to cause movement or deformation. It is measured in Newtons (N) using a force gauge. A force of 40N means 40 Newtons are being applied to an object. The significance of 40N depends on context and can be increased or decreased through various means.

If a student out fishing pulls on a fish with a force of 40 N and the fish pulls back with a force
of 40 N, what is the force exerted on the student and the fish at the same time?

40+40= 80N?

is that correct?

No. Think about Newton's 3rd law.

Yes, that is correct. The total force exerted on the student and the fish at the same time would be 80 N, as the two forces are equal and opposite, resulting in a net force of 0 N. This is known as Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In this scenario, the student's 40 N force is the action and the fish's 40 N force is the reaction.
 

1. What is the definition of exerted force?

Exerted force is the physical effort or energy that is applied to an object to cause it to move, change direction, or deform.

2. What does a force of 40N mean?

A force of 40N means that 40 Newtons of force is being applied to an object. Newtons are the unit of measurement for force in the International System of Units (SI).

3. How is exerted force measured?

Exerted force is measured using a device called a force gauge, which uses a spring or other mechanism to measure the amount of force being applied to an object. The unit of measurement for exerted force is Newtons (N).

4. What is the significance of having 40N of exerted force?

The significance of having 40N of exerted force depends on the context in which it is being used. It could represent the amount of force needed to move an object, or the amount of force being applied by an object. It is important to consider other factors, such as the mass of the object, when determining the significance of exerted force.

5. Can exerted force be increased or decreased?

Yes, exerted force can be increased or decreased. This can be done by applying more or less physical effort, changing the direction of the force, or using mechanical devices to amplify or reduce the force being applied.
