In physics, what is the term for the rate at which velocity changes over time?
Hint: Its unit of measurement is meters per second squared (m/s²)
Acceleration refers to the rate at which an object's velocity changes over time,
Acceleration refers to the rate at which an object's velocity changes over time, expressed as a vector quantity with both magnitude and direction.
It plays a key role in understanding motion and is influenced by forces acting on the object according to Newton's Second Law of Motion.
Acceleration can be positive (speeding up) or negative (slowing down, often called deceleration). Its unit of measurement is meters per second squared (m/s²).
What about the other answers?
Displacement: Measures the change in an object's position, unrelated to changes in velocity over time.
Speed: Refers only to how fast an object is moving, without considering direction or rate of change.
Momentum: Refers to the product of an object's mass and velocity, not the rate of velocity change.
