You need to recall which quantities are vectors and which are scalars. The vectors are displacement, velocity, acceleration, force, weight and momentum. Each of these has a magnitude and a direction.
The scalars are distance, speed, mass and energy. Each of these has magnitude only. Notice that the first two pair up with vectors: distance is a scalar and displacement is a vector, speed is a scalar and velocity is a vector.
Mass and weight are also different in this way. Mass is the amount of matter in an object, so it is a scalar. Weight is the force of gravity acting on a mass, so it is a vector.
