identifying positive and negative acceleration\nstudy the image of the roller coaster, then answer the questions. note that the arrows indicate the direction of the movement of the roller coaster train.\nwhich section (a or b) of the roller coaster shows positive acceleration?\nwhich section (a or b) of the roller coaster shows negative acceleration?
Answer
Explanation:
Step1: Understand positive acceleration
Positive acceleration occurs when an object speeds up. In section A, the roller - coaster is moving downwards and gravity causes it to speed up.
Step2: Understand negative acceleration
Negative acceleration (deceleration) occurs when an object slows down. In section B, the roller - coaster is moving upwards against gravity, which causes it to slow down.
Answer:
Positive acceleration: A Negative acceleration: B
