Do you remember the value of gravitational acceleration appeared in previous chapters in I/GCSE Physics? 👨🏫
- We know that if air resistance is negligible then any object falling freely under the effect of gravity has an acceleration of 9.81 m/s2.
🚨This value always appear in I/GCSE Math! 👩🏫
- This will not be the case if air resistance is significant. The acceleration will actually decrease as the speed of the object increases. This is explained below.
Consider an object released from rest and allowed to fall vertically:
This is the end of the topic!
