Question

acceleration is only when an object speeds up. false true

Explanation:

Acceleration is a vector quantity that measures the rate of change of velocity. Velocity has both magnitude (speed) and direction. So, acceleration occurs not only when an object speeds up (positive acceleration in the direction of motion) but also when it slows down (negative acceleration or deceleration, which is still acceleration as it's a change in velocity) and when it changes direction (even if speed remains constant, like in circular motion).

Answer:

False
