Why does butter melt if you leave it in a room?
The air in the room has a higher temperature than the butter, which means the particles in the air have more kinetic energy than the butter's particles. Collisions between the air's particles and the butter increase the temperature of the butter.

Define Inertia
Inertia is the property of matter by virtue of which it opposes any change in its state of rest or state of uniform motion along a straight line.
