This video is a review of Two Dimensional Vectors. This video goes over applications of vectors. 3 examples are covered illustrating how to find the resultant force.

Practical - Force and Acceleration

Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector. The magnitude of a vector is obtained by taking the square root of the sum of the squares of the components of the...

This video explores the behavior of objects when they fall under gravity. It starts with a quick recap of Newton's Second Law, which explains the relationship between force, mass, and acceleration. The video then looks at how weight is...

This is a lecture video on Newton's first law that explains how the force applied to objects affects their motion. The video starts with a recap of forces and how multiple forces can be combined to give a resultant force. The video then...

Learn how to add/subtract vectors. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we simply add each of the corresponding components of the vectors.

A force is a push or a pull that acts on an object.



Forces are vector quantities because they have both magnitude and direction, and so can be represented by an arrow. Scalar quantities have only magnitude and no...

Learn how to determine the unit vector of a vector in the same direction. The unit vector is a vector that has a magnitude of 1. The unit vector is obtained by dividing the given vector by its magnitude.

The video is a lecture on non-colinear resultant forces and how multiple forces acting on an object at angles to one another can affect it. The speaker initially explains collinear forces and how to find the resultant force. They then...

This video explains the concept of inertia and how it is quantified in terms of an object's mass and acceleration. The video uses examples of cars and lorries to demonstrate how larger masses require greater forces to be accelerated at...

The video discusses the differences between scalar and vector quantities, and how force is a vector quantity. The video also shows examples of vector quantities and how they can be represented by arrows. It also explains how multiple...

Find the direction and magnitude of the resultant vector of two forces

This video explains how to calculate the force experienced by an object when it is submerged in a fluid, specifically focusing on upthrust and fluids. The video also covers the concepts of pressure, density, gravitational field strength...

Newton's First Law | Force & Motion | Physics | FuseSchool In Physics we have three fundamental Laws of Motion created by Sir Isaac Newton way back in the 17th century. Today we are looking at the first law of motion, sometimes called...

The resultant force vector is the vector sum of all other external forces. This can be found graphically by placing the arrows on top of each other or analytically by summing up all horizontal and vertical components.

An object may have several different forces acting on it, which can have different strengths and directions. But they can be added together to give the resultant force. This is a single force that has the same effect on the object as all...
