A2 lesson, force in a circle
Describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle
Express angular displacement in radians
Recall and use centripetal acceleration
a = v2/r
Apply the equation F = ma to uniform motion in a circle to derive F = mv 2/r
