In which direction does friction act relative to the motion of an object?

• At a 45-degree angle to the direction of motion

• Perpendicular to the direction of motion

• Opposite to the direction of motion

• In the same direction

What happens to the arrows representing forces if an object is moving at a constant velocity?

• The arrows are of different lengths

• The arrows are the same length

• The arrows point in random directions

• There are no arrows

If a container is suspended and not moving, what can be said about the forces acting on it?

• The forces are in the same direction

• There are no forces acting on it

• The forces are balanced

• The forces are unbalanced

After today's lesson, how confident do you feel in identifying the forces acting on an object in a free-body diagram?

• Very confident – I can label all forces and understand their directions.

• Somewhat confident – I can identify most forces but might need more practice.

• Neutral – I understand the concept but still feel unsure about applying it.

• Struggling – I find it challenging to understand and apply free-body diagrams.

• Completely lost – I need more help to grasp the basics.
