Worked Solution & Example Answer:Momentum is conserved in collisions provided that A no crumpling of objects occurs B no energy is lost as heat or sound C no external forces act D no friction is involved (b) A student uses a horizontal air track to investigate collisions - Edexcel - GCSE Physics - Question 1 - 2016 - Paper 1
Step 1
Complete the sentence by putting a cross (X) in the box next to your answer.
Answer
The correct option for the conservation of momentum is:
C no external forces act
This choice indicates that for momentum to be conserved in a collision, there should be no external forces acting on the system.
Step 2
The student uses a horizontal air track to investigate collisions. What measurements are taken?
Answer
The student measures the following:
- Mass of glider M_1: 0.21 kg
- Mass of glider M_2: 0.21 kg
- Velocity of glider M_1 as it passes through the light gate: 0.47 m/s.
These measurements will be used to analyze the momentum before and after the collision.
