According to Newton's first law about motion, objects or bodies show a resistance to change their state this includes static objects or those that move. In this way, an object will not change its movement or state except if forces act on it, this is commonly known as inertia. Additionally, inertia and mass (quantity of matter) are closely related as the greater the mass the higher resistance, this can be explained as greater external forces are necessary to change the state of the object if the mass is greater. Thus, it is true the greater the mass is in an object, the higher the resistance to a change in movement the object will have.
Pretty sure physical, a chemical change would be something of the time of acid rain, meanwhile physical changes are the ones that affect the form not the actual chemical composition
For every action there is an equal and opposite reaction." So that applies to a roller coaster, between the ride vehicles and the track. When a ride goes up and down the hill, it creates different forces onto the track.
