Circular motion changes velocity

Circular motion changes velocity

Circular path showing velocity vectors tangent to the path at two points

Speed is a scalar quantity, but velocity is speed in a stated direction. An object moving in a circle can have constant speed while its velocity changes because its direction changes continuously.

2.4 Circular motion, inertia and momentum Lesson

  1. GCSE
  2. /Physics
  3. /2.4 Circular motion, inertia and momentum

Step-by-step lessons on Edexcel GCSE Physics 2.4 Circular motion, inertia and momentum, covering 2.4.1 Circular motion and centripetal force, 2.4.2 Inertial mass, 2.4.3 Newton's third law and momentum in collisions, and 2.4.4 Force and rate of change of momentum. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
