What is the unit for mass?

• Kilogram (Kg)
• Newton (N)
• Joule (J)
• Watt (W)

The unit used to measure work is the 

• Watt
• Newton
• Joule
• meter

What is the equation for work?

• Work = mass * acceleration
• Work = force * distance
• Work = force/distance
• Work = speed/time

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

• power
• work
• momentum
• Watt

In which of these cases is work being done? 

• A student sleeps
• A student pushes a locked door that does not move
• a student carries his chair into another room
• A student sits on the carpet

• 50,000 J
• 5,000 J
• 500 J
• 50 J

The amount of work done in a certain amount of time is known as 

• work
• effort force
• resistance force 
• power

The more POWER you use to move an object, the more work you do. 

• True
• False
