Because they are regular verbs. The past tense and past participle are always the same and always end in -ed.
Irregular verbs, however, don't follow this pattern and are all different. You must learn their forms.
Some words in the past tense are the same as the past participle because they are irregular verbs. English has many irregular verbs that do not follow the standard rule of adding "-ed" to form the past tense and past participle. Instead, these irregular verbs have a different form for both the past tense and the past participle. Examples include "go/went/gone" or "eat/ate/eaten."
The past tense and the past participle of think are the same: thought.
The past tense is "came" and the past participle is "come", which in this irregular verb has the same form as the present tense.
The past tense of "sick" is "sicked," and the past participle is also "sicked."
The past participle of "crept" is "crept." It remains the same in both the past tense and past participle forms.

The past tense is broke, and the past participle is broken.)

No, they are not the same. The past participle is a form of the verb that typically ends in -ed or -en and is used in various verb tenses, while the past tense specifically refers to the tense used to describe actions that have already happened.

In past participle, the rule is to add "had" then the past participle of the verb. Since the past tense and the past participle of jump is the same (jumped), then it should be "had jumped".
