Forces on Inclined Planes

This video tutorial covers the concepts of force diagrams and free body diagrams, explaining their differences and how to draw them. It includes examples such as a van on a hill and a block on an inclined plane, demonstrating how to resolve forces into parallel and perpendicular components. The tutorial emphasizes the importance of labeling and drawing arrows correctly, as these are key elements examiners look for.

What is the primary difference between a force diagram and a free body diagram?

• The direction of forces

• The number of forces included

• The way the object is represented

• The type of forces shown

In a free body diagram, what should you draw to represent the object?

• A rectangle

• A triangle

• A square

• A big dot or circle

When drawing a free body diagram, what is essential to include with each force?

• Color coding

• Labels and arrows

• Dashed lines

• Shaded areas

In the van example, which force acts perpendicular to the inclined plane?

• Weight

• Friction

• Tension

• Normal force

What is the tension applied to the block in the second example?

• 150 Newton

• 250 Newton

• 100 Newton

• 200 Newton

Which force opposes the movement of the block down the slope?

• Friction

• Normal force

• Tension

• Weight

How can the weight of an object on an inclined plane be resolved?

• Into normal and applied force components

• Into tension and friction components

• Into parallel and perpendicular components

• Into horizontal and vertical components

What trigonometric function is used to calculate the parallel component of weight?

• Cosine

• Tangent

• Sine

• Secant

What should you ensure when drawing lines in a free body diagram?

• They touch the object

• They are dashed

• They are colored

• They are thick

What should you check in the question before drawing a free body diagram?

• The color of the object

• The type of forces required

• The speed of the object

• The size of the object
