Check Your Understanding: Momentum & Impulse

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 —Fight scenes, sudden stops, mid-air catches, and forward rolls during the Cry of Jelicuon war reenactment

S9FE-IIIb-23Grade 9 · Quarter 3Momentum, Impulse & Change in Motion
1
Conceptual

Two performers run at the same speed, but one carries a heavy prop cannon and the other a light flag. Who is harder to stop, and what quantity describes this?

2
Problem Solving

A 50 kg performer charges across the stage at 4 m/s during the revolt scene. What is their momentum?

m = 50 kg, v = 4 m/s

3
Conceptual

When landing a jump off the riser, performers bend their knees instead of landing stiff-legged. Using impulse, how does this protect them?

4
Problem Solving

A 0.5 kg prop ball is caught, slowing from 6 m/s to 0 in 0.2 s. What average force is needed to stop it?

m = 0.5 kg, Δv = 6 m/s, t = 0.2 s

5
Conceptual

Why is a head-on collision in a poorly-rehearsed fight scene more dangerous than a glancing one at the same speed?
