Forces and Friction Flashcard

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of motion.

Front

A force is a push or pull measured in what units?

Back

A force is measured in Newtons (N).

Front

What is an example of friction that is harmful?

Back

Engine parts wearing out is an example of harmful friction.

Front

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

Back

Sliding friction occurs when an object is sliding over a surface.

Front

What is one way to reduce friction?

Back

Making the surfaces smoother is one way to reduce 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.

Front

What is kinetic friction?

Back

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

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, such as a wheel.

Front

What is fluid friction?

Back

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

Front

How can lubricants reduce friction?

Back

Lubricants, such as oils and greases, create a smoother surface between two objects, reducing friction.
