Negative Acceleration Examples
Acceleration refers to the rate of change of velocity of an object with respect to time. When an object is experiencing negative acceleration, it means that its velocity is decreasing. Here are five examples of negative acceleration:

1. Car Braking
When a car applies its brakes, it experiences negative acceleration as its velocity decreases. This can be observed when a car slows down to come to a stop at a traffic signal or when approaching a sharp turn.

2. Freefalling Object
An object falling towards the ground under the influence of gravity experiences negative acceleration. As it falls, its velocity increases until it reaches terminal velocity, where air resistance balances out gravity.

3. Sliding a Book Across a Table
If a book is pushed across a table and then comes to a stop, it experiences negative acceleration. The force of friction between the book and the table causes the book to slow down and eventually stop.

4. Throwing a Ball Upwards
When a ball is thrown upwards into the air, it experiences negative acceleration as it moves against the force of gravity. As it reaches its peak height, its velocity decreases until it momentarily stops before falling back down.

5. Slowing Down on a Bicycle
When a person on a bicycle applies the brakes to slow down, the bicycle experiences negative acceleration. The friction between the brakes and the wheels causes the bicycle to decelerate, reducing its velocity.
