Each seat has a high kinetic energy because the coaster is metal therefore has a bigger mass, and is is going very fast.

# data[].attributes.body
The coaster is at the highest point, therefore since the mass and g will not change, the coaster will have its highest potential energy.

# data[].attributes.body
The string is continuously pulling the seat inward and keeping it in a circular path.

# data[].attributes.body
The boat is oscillating from left to right and reaches its highest potential energy each time.

The boy's hand is no longer on the ball, which means gravity is the only force acting upon it.

# data[].attributes.body
The guy pushing the cart is adding an applied force which changes the momentum of the cart from rest to moving.

# data[].attributes.body
The boy is pushing the ball downward, which is parallel to the balls motion.

# data[].attributes.body
The cart would have stayed at rest until the applied force of the tracks made the cart continue to travel forward.

# data[].attributes.body
The ride increases speed as it travels downward, therefore it has positive acceleration until it gets past its lowest point.

# data[].attributes.body
After passing its lowest point, the ride continues to travel upward while its velocity decreases which is a negative acceleration until it reaches its highest point.
