Work Formula Quiz

What is the formula to calculate work done?

• work done = force / distance

• work done = force - distance

• work done = force + distance

• work done = force × distance

If a force of 20 N is applied to move an object a distance of 5 meters, what is the work done?

• 10 J

• 100 J

• 200 J

• 50 J

What is the unit of work?

• Joule

• Volt

• Watt

• Newton

If no displacement occurs, is work done?

• Yes

• Sometimes

• No

If a force of 10 N is applied to move an object a distance of 2 meters, what is the work done?

• 20 J

• 30 J

• 5 Nm

• 15 Nm

If the force and displacement are in the same direction, what can you say about the work done?

• The work done is positive.

• The work done is negative.

• The work done is undefined.

• The work done is zero.

If the force and displacement are in opposite directions, what can you say about the work done?

• The work done is positive.

• The work done is undefined.

• The work done is negative.

• The work done is zero.

If the work done is negative, what does it indicate?

• The work done is zero.

• The work done is in the same direction as the displacement.

• The work done is in a random direction.

• The work done is in the opposite direction of the displacement.

If a force of 30 N is applied to move an object a distance of 3 meters, what is the work done?

• 90 J

• 10 J

• 60 J

What is the work done when the displacement is zero?

• Zero

• Positive

• Negative

• Undefined
