• velocity
• acceleration
• mass

Objects that are changing their speed or their direction 

• force
• energy
• acceleration
• friction

as mass increases, the acceleration has to decrease: the law of acceleration

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
