Changes in Velocity:
* Speeding up: The object's velocity increases in magnitude. This is the most common association with acceleration.
* Slowing down: The object's velocity decreases in magnitude. This is sometimes referred to as deceleration or negative acceleration.
* Changing direction: The object's velocity changes direction, even if its speed remains constant. This happens in circular motion, for example.
Force and Momentum:
* Force is acting on the object: Acceleration is caused by a net force acting on the object, as stated by Newton's Second Law of Motion (F=ma).
* Momentum changes: Since momentum is the product of mass and velocity, an object's momentum changes as it accelerates.
Other Effects:
* Work and energy transfer: Acceleration requires work to be done on the object, transferring energy to it.
* Changes in potential energy: For example, an object accelerating upward gains potential energy.
* Changes in kinetic energy: An object accelerating gains kinetic energy, which is the energy of motion.
Examples:
* A car speeding up from a stoplight.
* A ball rolling down a hill.
* A satellite orbiting Earth.
* A person jumping off a diving board.
