What are the main equations I need to know when studying forces and acceleration?

The essential equations, at least at GCSE level, I call them the “suvat” equations.
They each contain some of the values below:
s = distance travelled
u = initial velocIty
v = final velocity
a = acceleration
t = time spent
There are four equations:
1. s = ut + (1/2)at^2
2. v = u + at
3. v^2 = u^2 + 2as
4. s = vt
All of these equations assume constant acceleration.

At Scoodle we understand that everyone learns in a different way. Some people learn through practice, using essays and notes; others prefer video lessons to watch and learn, some just need help with a specifically hard question, while some learn best 1-on-1 tutoring sessions. At Scoodle we cater for all types of learning styles and needs. From GCSE Maths video lessons to A-level English essays and specialist educators in every subject - we’ve got you covered.

Scoodle has helped over 131,000 students so far
