Advanced Science Primary 6 Interactions

Ravi conducted an experiment by releasing a block from the top of a ramp. He repeated the experiment by changing only the surface of the ramp. Which of the following correctly identifies the force arrows acting on the block as it slides down?

A X: Normal force, Y: Weight, Z: Friction
B X: Friction, Y: Weight, Z: Normal force
C X: Weight, Y: Friction, Z: Normal force
D X: Friction, Y: Normal force, Z: Weight

Worked Solution

Step 1: Identify arrow Y. It acts vertically downwards, representing Weight. Step 2: Identify arrow X. It acts parallel to the slope and opposes the motion, representing Friction. Step 3: Identify arrow Z. It acts perpendicular to the surface, representing Normal force. Step 4: Final Answer: X: Friction, Y: Weight, Z: Normal force.

Correct answer: X: Friction, Y: Weight, Z: Normal force
