Flashcard: Forces-Friction 2024

Front

What type of friction do wheels on a shopping cart experience?

Back

Rolling friction.

Front

Do balanced forces change the motion of an object?

Back

No, balanced forces do not change the motion of an object.

Front

What is the net force on an object if the forces acting on it are 20 N to the right?

Back

20 N to the right.

Front

Which type of friction is greater: static friction or moving friction?

Back

Static friction is greater than moving friction.

Front

What is the net force on a wagon if the forces acting on it result in 90 N to the right?

Back

90 N to the right.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What are the two main types of friction?

Back

Static friction and kinetic (or sliding) friction.

Front

What is the difference between sliding friction and rolling friction?

Back

Sliding friction occurs when two surfaces slide against each other, while rolling friction occurs when an object rolls over a surface.

Front

What happens to the motion of an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).
