Question

what is the difference between velocity and acceleration?
a. velocity describes an objects position and acceleration describes how fast it moves.
b. velocity is how fast an object moves and acceleration is the rate of change in velocity.
c. velocity is used to determine the magnitude of force acting on an object, and acceleration isnt.
d. velocity is a time - dependent property of an object, while acceleration is not.
please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Option A: Velocity does not describe position (position is related to displacement), and acceleration is not about how fast an object moves (speed/velocity is), so A is wrong.
• Option B: Velocity is the rate of change of position (how fast and in what direction an object moves), and acceleration is the rate of change of velocity (change in speed, direction, or both). This matches the definitions.
• Option C: Both velocity and acceleration are related to force (via \( F = ma \) and momentum which involves velocity), so C is wrong.
• Option D: Both velocity and acceleration can be time - dependent (e.g., in non - uniform motion), so D is wrong.

Answer:

B. Velocity is how fast an object moves and acceleration is the rate of change in velocity.
