Physics Laws of Motion Flashcard (no drawing)

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What are the types of friction?

Back

The main types of friction are static friction, sliding (kinetic) friction, rolling friction, and fluid 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 sliding (kinetic) friction?

Back

Sliding 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 experienced by an object moving through a liquid or gas.

Front

How does friction affect motion?

Back

Friction slows down moving objects and can prevent them from starting to move.

Front

What is the purpose of a hydrodynamic shape?

Back

A hydrodynamic shape is designed to move efficiently through water, reducing drag.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
