Check Your Understanding: Forces

A mix of conceptual and problem-solving items covering the whole module. Try each one yourself first, then reveal the answer to check. Problem items show the final answer only — work the full solution in your science journal.

Festival context —Prop construction with carpentry and wielding, carrying risers and equipment, fight scenes, and performer lifts during the Cry of Jelicuon reenactment

S9FE-IIa-16Grade 9 · Quarter 2Newton's Laws, F = ma, Friction & Equilibrium
1
Conceptual

During a sudden stop in the fight scene, a performer's wooden rifle keeps sliding forward out of their grip. Which of Newton's laws explains this?

2
Problem Solving

A performer pushes a 20 kg prop cart with a net force of 40 N. What is its acceleration?

F = 40 N, m = 20 kg

3
Conceptual

When two performers shove against each other's shields in a battle scene, what does Newton's Third Law predict about the forces they feel?

4
Problem Solving

What net force is needed to accelerate a 5 kg prop shield at 3 m/s²?

m = 5 kg, a = 3 m/s²

5
Conceptual

Why do performers wear rubber-soled shoes instead of smooth leather when dancing on the concrete plaza?

6
Conceptual

A tall prop tower is stored upright in the equipment room. What does it mean for it to be in equilibrium, and how do you make it more stable?
