Work or Not Work

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as the product of force and distance (Work = Force x Distance).

Front

When is work considered to be done?

Back

Work is considered to be done when an object is displaced in the direction of the applied force.

Front

Is standing still while holding a heavy object considered work?

Back

No, standing still does not involve displacement, so no work is done.

Front

What is the formula for calculating work?

Back

Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

If you throw a baseball a distance of 20 meters, is that work?

Back

Yes, because the baseball is displaced in the direction of the force applied.

Front

Does carrying an object horizontally while walking constitute work?

Back

Yes, if the object is being lifted against gravity and moved horizontally, work is done.

Front

What is the difference between work and energy?

Back

Work is the transfer of energy through force and movement, while energy is the capacity to do work.

Front

Is waiting for a bus in the cold considered work?

Back

No, because there is no displacement of an object in the direction of a force.

Front

What happens to the work done if the distance is zero?

Back

If the distance is zero, then no work is done, regardless of the force applied.

Front

Can work be done if the force is applied at an angle?

Back

Yes, work can still be done if the force is applied at an angle, but it must be calculated using the cosine of the angle.
