Areal gas will behave most like an ideal gas under conditions of

high temperature and low pressure

Explanation:

The Ideal Gas equation is:  

Where:  

is the pressure of the gas  

is the volume of the gas

the number of moles of gas  

is the gas constant  

is the absolute temperature of the gas in Kelvin

According to this law, molecules in gaseous state do not exert any force among them (attraction or repulsion) and the volume of these molecules is small, therefore negligible in comparison with the volume of the container that contains them.  

Now, real gases can behave approximately to an ideal gas, under the conditions described above and taking into account the following:  

When temperature is high a real gas approximates to ideal gas, because the molecules move quickly, preventing the repulsion or attraction forces to take effect.  In addition, at low pressures, the volume of molecules is negligible.

car stops. he keeps going = he has inertia

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
