General Physics 1 - Unit 7: Work, Power, and Energy

The product of force and the distance moved in the direction of the force.

A real-world example of calculating work done.

Work done in real-world situations like building, bungee jumping, and human activities.

The standard unit of work is the Joule.

Converting energy from one form to another in real-life situations.

The rate at which work is done (or energy is transferred).

Activities like standing, walking, and running have different energy requirements.

Converting between units of energy, such as Joules and Calories.

A mathematical operation that takes two vectors and returns a scalar value.

Calculating work done by a constant force, which is the product of the force's magnitude and the displacement's magnitude, considering the angle between them.

Calculating work done by a force that changes strength during movement, often involves calculus to determine the area under the force-displacement graph.

A push or pull that can cause an object to change its motion.

The change in the position of an object.

A dot product which yields a scalar value. For example, the magnitude of force and distance moved in the same direction gives a scalar (work).

The process of using force on an object to move it from point A to point B.

Change in displacement caused by a constant force

Change in displacement is influenced by a varying force

The force and displacement are perpendicular (90 degrees) to each other.

Work can be either positive or negative, depending on the angle between force and displacement.

No change in displacement occurs when a constant force is applied during a given interval.

Work is a scalar quantity.

Work can be determined graphically; the area under the force-displacement graph.

Acceleration is not a direct factor in determining work.
