What is kinetic friction?

Back

The friction that occurs when two objects are sliding against each other.

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

What is the effect of friction on motion?

Back

Friction opposes the motion of an object.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion, while kinetic friction acts on moving objects.
