Applied Science AQA/Kinematics

Kinematics

A brief paragraph about where this science is used

Syllabus Content	What you need to do
• the motion of objects	Describe motion in terms of displacement, speed, velocity and acceleration. Know the difference between: - distance and displacement - speed and velocity
• the formulas : (average) v = s/t v = u + at v² = u² + 2as s = ut + ½ at²	Use these suvat equations to calculate any of the five quantities. Recognise 'hidden' information, such as a=9.81 ms⁻² when falling, or that accelerating from rest gives u = 0 ms⁻¹.
• representing motion through the use of graphs of displacement against time and velocity against time	Use these graphs to describe motion. Calculate the gradient of a displacement-time graph as speed. Calculate the gradient of a velocity-time graph as acceleration. Calculate the area under a velocity-time graph as distance traveled. (Gradients may require the calculation of the tangent to a curve at a point.)

Solution

to exemplify level required – level checked by AQA

– can we use old AQA qs… e.g. from more than 5 years ago? With Examiner comments
