Soal Latihan Hukum Hooke

1.

Berikut yang merupakan satuan konstanta pegas adalah.....

A.

N/m
B.

N
C.

M
D.

M/N

Correct Answer
A. N/m

Explanation
The correct answer is N/m. This is because N/m represents the unit for the spring constant, which measures the stiffness of a spring. The unit N represents Newton, which is the unit for force, and m represents meter, which is the unit for displacement. Therefore, N/m represents the force per unit displacement, indicating the strength of the spring's resistance to stretching or compressing.

Pernyataan mana saja yang sesuai dengan Hukum Hooke?

A.

Semakin besar gaya yang bekerja pada pegas, maka semakin kecil pertambahan panjang pegas
B.

Semakin besar gaya yang bekerja pada pegas, maka semakin besar pertambahan panjang pegas
C.

Semakin besar nilai konstanta pegas, maka makin besar pertambahan panjang pegas
D.

Semakin besar nilai konstanta pegas, maka makin kecil pertambahan panjang pegas

Correct Answer(s)
B. Semakin besar gaya yang bekerja pada pegas, maka semakin besar pertambahan panjang pegas
D. Semakin besar nilai konstanta pegas, maka makin kecil pertambahan panjang pegas

Explanation
The correct answer options are consistent with Hooke's Law. According to Hooke's Law, the extension or deformation of a spring is directly proportional to the force applied to it. Therefore, as the force applied to the spring increases, the extension of the spring also increases. This is reflected in the statement "Semakin besar gaya yang bekerja pada pegas, maka semakin besar pertambahan panjang pegas" (The greater the force acting on the spring, the greater the extension of the spring). Additionally, Hooke's Law states that the constant of proportionality (spring constant) determines the stiffness of the spring. So, as the spring constant increases, the extension of the spring decreases, which is expressed in the statement "Semakin besar nilai konstanta pegas, maka makin kecil pertambahan panjang pegas" (The greater the value of the spring constant, the smaller the extension of the spring).

Jika sebuah pegas ditarik dengan gaya 50 N ke arah barat, maka pegas akan memberi gaya reaksi ke arah timur dengan besar ditentukan oleh konstanta pegas

A.

True
B.

False

Correct Answer
B. False

Explanation
False. When a spring is pulled with a force of 50 N in the west direction, the spring will exert a reaction force in the east direction. The magnitude of the reaction force is determined by the spring constant.

Saat pegas ditarik sejauh x cm, maka pegas menyimpan sejumlah energi yang disebut sebagai energi ________

Correct Answer
potensial, potensial pegas

Explanation
When a spring is stretched or compressed, it stores potential energy. This potential energy is known as the potential energy of the spring or pegas.
