Physics

Example output

Formulas with their units and meanings, taken from your own working.

Summary

Your notes list the equations of motion correctly, but units are inconsistent between examples — two of the worked solutions use km/h without converting. That's the most likely source of lost marks here, not the physics itself.

Equations of motion

All four SUVAT relationships are present, with worked examples for constant acceleration.

Unit consistency

Two examples mix km/h with metres and seconds. Convert before substituting, always.

Key terms

Accelerationpage 8
Rate of change of velocity, measured in m/s².
Displacementpage 8
Distance in a given direction — a vector, unlike distance.
Terminal velocitypage 14
The constant speed reached when drag equals weight.
Formula sheet built from your working
v = u + at
final velocity from initial velocity and acceleration
s = ut + ½at²
displacement over time under constant acceleration
v² = u² + 2as
velocity and displacement, without needing time
F = ma
resultant force equals mass times acceleration

Flashcards

v = u + at — what does each term mean?
Final velocity = initial velocity + acceleration × time.
Units of acceleration?
m/s² — metres per second squared.
What happens at terminal velocity?
Resultant force is zero, so acceleration is zero and speed stays constant.

Practice question

A car accelerates from rest at 3 m/s² for 4 s. What is its final velocity?

Pick an answer to see the reasoning.
