Front

What is the definition of mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What are the two main types of friction?

Back

Static friction and kinetic friction.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.
