Question

newtons first law quick check
which of the following describes velocity? (1 point)
velocity is a force that changes an objects speed and/or direction.
velocity is the sum of all of the forces acting on an object.
velocity is the resistance of an object to a change in its speed or direction.
velocity is the speed of an object in a particular direction.

Explanation:

Velocity is a vector quantity. A vector has both magnitude (speed) and direction. The first option is incorrect as velocity is not a force. The second option describes net force. The third option describes inertia. The fourth option correctly combines speed (magnitude) and direction which is the definition of velocity.

Answer:

Velocity is the speed of an object in a particular direction.
