Question: What is the relationship between the units of energy (Joule) and force (Newton)? (2021)

Options:

Correct Answer: 1 J = 1 N·m

Exam Year: 2021

Solution:

1 Joule is defined as the work done when a force of one Newton moves an object one meter, hence 1 J = 1 N·m.

What is the relationship between the units of energy (Joule) and force (Newton)? (2021)

Step 1: Understand what a Joule is. A Joule (J) is a unit of energy.
Step 2: Understand what a Newton is. A Newton (N) is a unit of force.
Step 3: Learn the definition of work. Work is done when a force moves an object.
Step 4: Know the relationship between work, force, and distance. Work (in Joules) is equal to force (in Newtons) multiplied by distance (in meters).
Step 5: Write the formula for work: Work (J) = Force (N) × Distance (m).
Step 6: If a force of 1 Newton moves an object 1 meter, the work done is 1 Joule.
Step 7: Therefore, we can say that 1 Joule is equal to 1 Newton times 1 meter, or 1 J = 1 N·m.
