Standard Science Primary 6 Interactions

Look at the diagram of a block resting on a ramp. In which direction does the frictional force act?

A Direction A (Downwards)
B Direction C (Downwards along the slope)
C Direction B (Upwards along the slope)
D Direction D (Perpendicular to the slope)

Worked Solution

Step 1: Gravity tends to pull the block down the slope. Step 2: Friction acts in the opposite direction to the potential motion. Step 3: Therefore, friction acts upwards along the slope.

Correct answer: Direction B (Upwards along the slope)
