What is a change in position relative to a reference point, such as north, south, east, west, up, or down?
What is motion?
100
A bus is moving at a constant velocity of 30m/s, how can it change its velocity and become unbalanced?
What is by increasing its velocity or turning a corner?

Explain where the potential and kinetic energy is on top of a roller coaster hill and going down the hill and how some of the mechanical energy changes into thermal energy.
What is as you go up and down a roller coaster hill potential energy is converted into kinetic energy and back again. There is friction between the car's wheels and the track between the cars and the air around them. Some of the mechanical energy changes into thermal energy because of friction.

What is the net force on an object when you combine a force of 7N north with a force of 5N south?
What is 2 Newtons North?
200
What is the distance traveled by an object divided by the time taken to travel the distance?
What is speed?

200
Does the energy get lost or conserved when mechanical energy changes into thermal energy with the roller coaster's car's wheels and the roller coaster track? What is the name of this law?
What is the energy is never lost; it is conserved. This is called the law of conservation of energy.
