Any vector in an arbitrary direction can always be replaced by two (or three)-

If the component of one vector in the direction of another vector is zero, then those two vectors are _______

If the component of one vector in the direction of another vector is zero, then those two vectors are _______

What is meant by resolution of a vector ? Prove that a vector can be resolved along two given directions in one and only one way.

Any two collinear vectors are

For any four vectors veca, vecb, vec c , vecd (all non coplanar) any vector can be written as a linear combination of other three vectors.

Any three point are always collinear.

(A): Acceleration of a moving particle can change its direction without any change in direction of velocity. (R) : If the direction of change in velocity vector changes, the direction of accele ration vector also changes.

If component of one vector in the direction of another vector is zero, then those two vectors
