The word “hit” is simply bringing something in contact with something else. Such as “The hammer hit the nail.” Or “he hit the desk with his thigh when he walked by.”
Vs
Strike is an intentional force. Such as “You must strike the mallet down on the lever to see how strong you are.” Or commonly used to describe “A Lightning Strike.”
Strike is more commonly used as “struck”, such as “The lightning struck the tree, causing it to split in half.”
