What is work?

• the amount of energy 
• the transfer of force over a distance
• rate of work in a given time
• the change in distance in a given time

What is the equation for work?

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

• 70 J
• 1750 J
• 355 J
• 175 J
