Things in Motion: Acceleration

The video tutorial explains the concept of acceleration, starting with a car accelerating when the gas pedal is pressed. It describes positive acceleration using examples like a rocket and a bicycle going downhill. The tutorial also covers negative acceleration, or deceleration, with examples such as a skier slowing down and a car stopping at a stop sign. Acceleration is defined as a change in velocity, and deceleration is a decrease in velocity.

What is meant by positive acceleration? Provide an example.

Explain the term deceleration and provide a scenario where it occurs.
