Resolving Forces and Components

This video tutorial explains how to use vector diagrams to resolve a single force into two perpendicular components, focusing on higher-tier students. It begins with an introduction to the concept, followed by a detailed example of resolving a 100 Newton force at a 35-degree angle. The tutorial includes a practice problem for viewers to try, involving a 75 Newton force at a 20-degree angle. The video emphasizes the importance of drawing vector diagrams to scale and calculating the magnitudes of the horizontal and vertical components.

What is the main objective of this video tutorial?

• To study the effects of friction on motion.

• To explore the concept of gravitational force.

• To understand how to resolve a single force into two components.

• To learn how to calculate the resultant of two forces.

In which direction does a horizontal force act?

• Vertically

• Diagonally

• Horizontally

• In a circular path

What does a diagonal force indicate about its components?

• It acts only vertically.

• It acts only horizontally.

• It has no components.

• It has both horizontal and vertical components.

What is the first step in resolving a force using a vector diagram?

• Measure the angle with a protractor.

• Draw faint lines for the axes.

• Calculate the resultant force.
