AP Physics 1&2 Kinematics MC Quiz

A particle travels along a curved path between two points P and Q as shown. The displacement of the particle does not depend on

• the location of P.

• the location of Q.

• the distance traveled from P to Q.

• the shortest distance between P and Q.

• the direction of Q from P.

Answer explanation

Displacement is a VECTOR.
