What is the formula for work?

• Force = work x distance
• Distance = force x work
• Work = force x distance
• Work = force x mass

Which one is a unit of distance?

What is work?

• A push or pull.
• When the object moves in the same direction in which the force is exerted.
• A change in energy.
• The rate at which energy is transferred.
