• Newtons
• meters

A force exerted over a distance to move an object is ______________________.

• power
• work
• momentum
• Watt

Work is done only if

• a force is applied.

• the force applied causes the object's motion.

• an object is in motion.

In physics, we define work as this

• force x time
• force x distance
• force / time
• force / distance

In physics, power is identified as this

• force x distance
• distance / time
• work / time
• time / work

(a)  

Is the rate at which work is done, or the rate at which energy is converted.

(a)  

When a force moves an object in the direction of the force.
