Vertical Free Fall and Constant Horizontal Motion
Explanation:
The kinetic energy of an object is given in terms of its mass and object as :

An object with more mass has more kinetic energy. An object with less mass, if both objects are moving at the same speed, in opposite directions, will have less kinetic energy. The square of v will give positive number.
Answer:
"Gravitational force and the acceleration force" are the forces that are acting on a passenger while going through a loop.
Explanation:
When the passengers reach the top of the loop, The force of the car's acceleration pushes all the passengers off the seat and towards the center of the loop. On the other hand the inertia will try to push the passengers back into the seat. The gravity as well as the acceleration will tend to push the passenger in opposite direction with approximately equal force, which will create a feeling of being mass-less or we can call it weightlessness.
