Motion Velocity Reference point Speed

1. An object is in when its distance from a(n) is changing.

2. Speed is given direction is called

3. can be calculated if you know the distance that an object travels in one unit of time.

1. An object is in motion when its distance from another object is changing.

2.Speed is given direction is called velocity.

Speed can be calculated

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
