Question

For a particle undergoing non-uniform circular motion, which statements are correct?

G1 Physics · Accepted Answer

Velocity at any point is tangent to the circle. Radial acceleration always points toward the centre, so its direction changes as the particle moves. Tangential acceleration is parallel or antiparallel to velocity and therefore changes speed. Radial acceleration is perpendicular to velocity and changes only the direction of velocity, not its magnitude.
