Question

A meteor burns when it enters the earth atmosphere. This is due to the fact that:

• A. Gravitational force produces heat
• B. Frictional force produces heat
• C. Magnetic force produces heat
• D. Body moving with very high speed produces heat

Answer 1

The correct option is B

Frictional force produces heat

Friction can produce heat. This can be observed if you rub your palm against each other. Likewise, when a meteorite enters the earth's atmosphere, the air applies a frictional force against the motion of the meteorite. Due to this frictional force, heat is produced and the meteor starts burning.
