5/7- Do Now

What happens when a force is applied to an object but it does not move?

• Work is still done.

• Both energy is transferred and work is done.

• No work is done.

• Energy is not transferred.

What is required for work to be considered as being done?

• The force must be applied in the opposite direction of movement.

• An object must move in the direction of the applied force.

• A force must be applied without movement.

• An object must move in any direction.

What must happen for work to be done on an object?

• The object must be stationary.

• The object must move as the force is applied in the same direction.

• The force must be applied for a long duration.

• The object must move in any direction as long as force is applied.

How is work calculated in physics?

• W = D - F

• W = F / D

• W = F + D

• W = F x D

What unit is used to express work?

• Watt

• Joule

• Pascal

• Newton
