English regular verbs change their form very little (unlike irregular verbs). The past tense and past participle of regular verbs end in -ed, for example:
work, worked, worked
But you should note the following points:
1. Some verbs can be both regular and irregular, for example:
learn, learned, learned
learn, learnt, learnt
2. Some verbs change their meaning depending on whether they are regular or irregular, for example "to hang":
regular hang, hanged, hanged to kill or die, by dropping with a rope around the neck
irregular hang, hung, hung to fix something (for example, a picture) at the top so that the lower part is free
3. The present tense of some regular verbs is the same as the past tense of some irregular verbs:
regular found, founded, founded
irregular find, found, found
