Which situation describes a negative acceleration

Answer 1

There are several situations that can describe a negative acceleration. Here are a few examples:

1. A car coming to a stop: When you press the brakes in a car, it experiences a negative acceleration as it slows down.
2. A ball thrown upwards: When you throw a ball upwards, it experiences a negative acceleration due to the force of gravity pulling it downwards, causing it to slow down until it starts falling back to the ground.
3. A cyclist pedaling backwards: When a cyclist pedals backwards, the bike experiences a negative acceleration because they are applying a force opposite to the direction of motion, causing it to slow down.
4. A body sliding on a rough surface: When a body slides on a rough surface, it experiences a negative acceleration due to the friction acting in the opposite direction of its motion, causing it to slow down.
