Teacher Delivery Guide Mechanics: 3.03 Forces and Newton’s Laws OCR Subject Content Stage 2 learners additionally DfE Stage 1 learners should… should… Ref. Ref. 3.03 Forces and Newton’s Laws 3.03a first law a) Understand the concept and vector nature of a force. MR1 Newton’s A force has both a magnitude and direction and can cause an object with a given mass to change its velocity. Includes using directed line segments to represent forces (acting in at most two dimensions). Learners should be able to identify the forces acting on a system and represent them in a force diagram. 3.03b b) Understand and be able to use first law. Newton’s A particle that is at rest (or moving with constant velocity) will remain at rest (or moving with constant velocity) until acted upon by an external force. Learners should be able to complete a diagram with the force(s) required for a given body to remain in equilibrium.
