Question

multiple choice question
what is the speed and direction of an objects motion?

displacement
motion
vector
velocity

Explanation:

To solve this, we analyze each option:

• Displacement: It is the change in position (vector quantity but not defined as speed + direction).
• Motion: A general term for object's movement, not specific to speed and direction.
• Vector: A quantity with magnitude and direction, but it's a general category, not the specific term for speed + direction.
• Velocity: By definition, velocity is the speed of an object in a given direction, so it matches the description of speed and direction of motion.

Answer:

D. velocity
