Acceleration Calculations | GCSE Physics practice
Acceleration is the rate of change of velocity. It is a vector quantity.
What units are used for acceleration?
What is Acceleration Calculations | practice?
"The rate at which an object changes its velocity."
What is the resultant force on an object if a 10N force acts right and a 4N force acts left?
Which of these is the correct vector equivalent of 'Distance'?
An object moves at a constant velocity. What is the resultant force?
What is the unit of the spring constant (k)?
Calculating Acceleration
Acceleration = change in velocity / time taken (a = Δv / t).
Units are metres per second squared (m/s²).
Deceleration is just negative acceleration.
Uniform acceleration can be calculated using v² - u² = 2as.
Calc Tip: Change in velocity (Δv) is final velocity (v) minus initial velocity (u). Don't swap them!

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
