Got a Physics question no one is answering?

I’ve seen loads of students posting on Reddit and getting:

Let’s change that here.
Drop your question below and I’ll go through it clearly, step-by-step.

Here’s one to get started:

Question:A car accelerates from rest to 20 m/s in 5 seconds.

What is its acceleration?

Formula:

acceleration = change in velocity / time

Calculation:

a = (20 − 0) / 5 = 4 m/s²

Tip: In Physics, always:
