Describing Acceleration

Which statements describe acceleration? Check all that apply.

Negative acceleration occurs when an object slows down in the positive direction.

Negative acceleration occurs when an object slows down in the negative direction

Negative acceleration occurs when an object speeds up in the negative direction.

Positive acceleration occurs when an object speeds up in the positive direction.

Positive acceleration occurs when an object speeds up in the negative direction.

Positive acceleration occurs when an object slows down in the negative direction.

Negative acceleration occurs when an object slows down in the positive direction.

Negative acceleration occurs when an object speeds up in the negative direction.

Positive acceleration occurs when an object speeds up in the positive direction.

Positive acceleration occurs when an object slows down in the negative direction.

Explanation:

Acceleration is the increase in speed that an object shows or experiments in a certain time, so you have positive and negative acceleration depending on the negative and negative direction, for example when using the vertical plane falling would be negative direction and going up would be the positive direction, so any increase in speed in the positive direction that would be a positive acceleration, increase in the negative would be negative acceleration, and decreases in both would mean an opposite acceleration.
