Speeding up.
Example sentence - My car has a V8 engine with terrific acceleration.
A simple example of acceleration is a car speeding up from a stationary position at a traffic light. As the driver presses the gas pedal, the car's speed increases, showing acceleration.
Stepping on the brakes of a moving car is an example of
A real-life example of negative acceleration is when a car slows down to a stop at a red light. As the driver applies the brakes, the car's velocity decreases, resulting in negative acceleration.
Negative acceleration
Rather, a car stoppping at a light is an example of deceleration but one of the possible example of acceleration when a car stops at a traffic light is a pedestrian accelerating across the road or other car in different lanes accelerating to move to on in their journey.
When acceleration is opposite to (against) the direction of motion, the magnitude of the velocity decreases, meaning that the object slows down. An example is the application of the brakes to slow or stop a car. During the time that the pressure remains on the brake pedal, the car's acceleration is negative ... meaning opposite to the direction of motion ... and the car's speed is decreasing.

A car slowing down when the brakes are applied.
An example of acceleration in the direction of motion is when a car speeds up while driving on a highway. As the driver presses on the accelerator pedal, the car's velocity increases in the same direction as its motion, resulting in acceleration in the direction of travel.
An example of acceleration by decreasing speed is when a car is traveling at 50 miles per hour and then applies the brakes, causing the car to slow down to 30 miles per hour. The decrease in speed over time represents a negative acceleration, or deceleration, as the car is still changing its velocity.
You have acceleration any time a velocity changes - like when an object falls down due to gravity, when a car starts or stops, when you start moving or stop moving, etc.
