Friction Flashcard

Front

What is the net force acting on a hockey puck sliding on ice at a constant velocity?

Back

Zero

Front

How does the weight of an object affect the force of friction?

Back

The force of friction increases with the weight of the object.

Front

What is friction?

Back

Friction is a force that opposes motion.

Front

Friction acts in a direction ___________ of movement.

Back

opposite

Front

What is the coefficient of static friction if it takes 44 N of force to move an 86-N box on a horizontal surface?

Back

0.51

Front

Define static friction.

Back

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

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What factors affect the force of friction?

Back

The force of friction is affected by the weight of the object and the nature of the surfaces in contact.

Front

What is the formula for calculating the force of friction?

Back

Frictional force = coefficient of friction × normal force.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, while kinetic friction acts on an object in motion.
