Question

the direction and speed of an object is described by its ________. average displacement average speed displacement velocity

Explanation:

Velocity is a vector quantity that includes both the speed of an object and its direction of motion. Average displacement is the change in position divided by time and is also a vector but not what directly describes speed and direction together. Average speed is a scalar quantity (only magnitude, no direction). Displacement is the change in position and is a vector, but not focused on speed.

Answer:

D. velocity
