Understanding Work, Energy, and Power

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

• Movement in the same direction as the force

• Movement in the direction opposite to the force

• Force must be applied in any direction

• Force must be applied without movement

What is an example of a situation where no work is done?

• Driving a car on a flat road

• Pushing a stationary car

• Cycling up a hill

• Rolling a bowling ball

Which scenario describes work being done?

• Holding a heavy box stationary

• Pushing against a locked door

• Pulling a wagon downhill

• Carrying a backpack while standing still

What must happen for work to be done according to physics?

• An object must move in any direction

• An object must remain stationary

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

• An object must be lifted off the ground

Which example involves transferring energy from one object to another?

• A bowler releasing a bowling ball

• A fan blowing air

• A parked car

• A person sitting on a chair

What is the unit of work?

• Meter

• Newton

• Watt

• Joule

How is work calculated?

• Force multiplied by distance

• Force plus distance

• Force minus distance

• Force divided by distance

What is the formula for calculating work?

• W = F * D

• W = F / D

• W = F + D

• W = F - D

What does a joule measure?

• Speed

• Power

• Work

• Time
