2024 Forces & Friction Flashcard Review

Front

What type of friction would experience a balanced net force?

Back

Static friction is the type of friction that occurs when two surfaces are in contact but not moving relative to each other, resulting in a balanced net force.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is the net force?

Back

Net force is the overall force acting on an object when all the individual forces acting on it are combined.

Front

Which type of friction is the STRONGEST?

Back

Static friction is the strongest type of friction, as it must be overcome to start moving an object.

Front

What type of friction occurs when an object is sliding over a surface?

Back

Sliding friction, also known as kinetic friction, occurs when two surfaces slide against each other.

Front

What is rolling friction?

Back

Rolling friction is the force resisting the motion when an object rolls over a surface, typically less than sliding friction.

Front

What is fluid friction?

Back

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

Front

How does surface texture affect friction?

Back

Rough surfaces tend to have higher friction compared to smooth surfaces due to increased contact area and interlocking.

Front

What is the relationship between mass and friction?

Back

The greater the mass of an object, the greater the normal force, which typically increases the frictional force.

Front

What is the formula for calculating frictional force?

Back

Frictional force (F_f) = coefficient of friction (μ) × normal force (F_n).
