Sep 12, 2022 · We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction. Force can be represented by vectors or expressed as a multiple of a standard force.

Dec 4, 2017 · Like momentum, it is a covector or one-form, and covariant. You can see this in several ways: from the principle of virtual work: force is a linear function mapping infinitesimal displacements δx (a vector) to infinitesimal changes in energy Fδx (a scalar) and hence a covector by definition.
- Uhm ... you start with an object at rest and notice that if you push on it in different directions it moves in different directions? Then notice th...
- Vectors are things that add like little arrows. Arrows add tip to tail. Number of rocks is not a vector. 2 rocks + 2 rocks = 4 rocks. Displacement...

A force is a vector quantity which describes both the strength of the push or pull (the magnitude of the force vector) and the direction of push and pull. As we will see in the next few chapters both the strength and the direction of the force is essential to describing the dynamics of objects.
Key Terms. vector: A directed quantity, one with both magnitude and direction; the between two points. free-body diagram: A free body diagram, also called a force diagram, is a pictorial representation often used by physicists and engineers to analyze the forces acting on a body of interest. Curation and Revision.
A force has both magnitude and direction, therefore: Force is a vector quantity; its units are newtons, N. Forces can cause motion; alternatively forces can act to keep (an) object(s) at rest.

We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction. Force can be represented by vectors or expressed as a multiple of a standard force.
Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity. Created by Sal Khan. Questions. Tips & Thanks.
