This super fun activity for ages 5 and up helps students gain an intuitive feel for momentum.
What you’ll need:
Setting up the track::
The heavier car, pushed at the same speed as the lighter car, carries much more momentum. Some of that momentum is transferred to the lighter car.
Can you guess how fast the lighter car moves after the collision compared to its initial speed?
What happens to the heavy car in the above interactions? Does its speed change very much?
Think about it - an object with more momentum is less susceptible to changes in speed. How easy is it to stop a toy train? How easy is it to stop a full-size train?
The momentum from the first car is completely transferred to the second car! Does this depend on the speed of the first car?
This is a special case that only happens when the masses match!
If you’re able to make this happen, use the kitchen scale to measure the ratio of the loaded Hall’s Cars. Turns out the ratio will be about 3:1. Does this depend on the speed of the lighter car?
