Karet adalah benda yang bersifat elastis karena dapat mengalami perubahan bentuk saat diberikan tekanan atau tarikan, namun dapat kembali ke bentuk semula setelah tekanan atau tarikan tersebut dihilangkan. Karet memiliki sifat ini karena terbuat dari bahan yang fleksibel dan memiliki ikatan molekul yang dapat meregang dan kembali ke posisi semula.

The correct answer is "Gaya". In physics, force is defined as any push or pull that can cause an object to move, change direction, or deform. The term "gaya" in Indonesian translates to "force" in English. Therefore, "gaya" is the appropriate term to describe all forms of attraction and repulsion in physics.

The question is asking for the force that causes fruits to fall downwards. The correct answer is "Gravitasi" which means gravity. Gravity is the force that pulls objects towards the center of the Earth. When fruits fall, they are being pulled downwards by the force of gravity, causing them to fall towards the ground.

Playing with plastisin can change the shape of an object because plastisin is a malleable material that can easily be molded and reshaped.

The correct answer is "Ketapel" because a ketapel, also known as a slingshot, uses the force of a stretched elastic band (similar to a spring) to propel an object. This demonstrates the concept of a spring force, which is the characteristic of a pegas (spring). The other options, such as a kompor (stove), mobil (car), and kelereng (marbles), do not involve the use of a spring force.

Perahu layar dapat bergerak karena adanya dorongan. Dorongan ini bisa berasal dari angin yang mengenai layar perahu, sehingga menghasilkan gaya yang mendorong perahu maju. Gaya dorongan inilah yang membuat perahu layar dapat bergerak melawan arah angin dan melaju di atas permukaan air.

The correct answer is "Ban mobil dan jalan raya." Gaya gesek terjadi antara dua permukaan yang saling bersentuhan dan menghalangi gerakan relatif di antara keduanya. Dalam hal ini, ban mobil dan jalan raya saling bersentuhan saat mobil bergerak, dan gaya gesek terjadi antara keduanya yang menghalangi gerakan bebas ban mobil di atas jalan raya.

When two magnets with the same poles (north and north or south and south) are brought close to each other, they will repel each other. This is because like poles repel each other due to the magnetic field lines of both magnets pushing against each other. Therefore, the correct answer is "Saling menolak" which means "Repel each other" in English.

As the bowstring is pulled back further, the arrow will be propelled with more force and speed, resulting in it traveling a greater distance. Therefore, the correct answer is "Jauh" (far).

The statement "Piring yang dilempar jatuh kemudian pecah" implies that the plate was thrown with force, causing it to fall and break upon impact. This demonstrates that a force (gaya) can change the shape (mengubah bentuk) of an object, in this case, the plate.

The correct answer is "Rem sepeda" because it is the only object listed that utilizes frictional force. When the brakes of a bicycle are applied, the brake pads create friction against the wheel rims, causing the bicycle to slow down or stop. This frictional force is essential for controlling the speed and movement of the bicycle. The other objects listed, such as an arrow, slingshot, and compass, do not rely on friction to function.

Anak panah yang dilepaskan dari busurnya termasuk contoh gaya pegas. Ketika busur ditarik, energi potensial elastis disimpan dalam pegas busur. Ketika anak panah dilepaskan, energi potensial elastis tersebut berubah menjadi energi kinetik, menyebabkan anak panah meluncur ke depan. Gaya pegas terjadi karena adanya deformasi pada pegas yang kemudian menghasilkan gaya restoratif yang kembali ke bentuk semula setelah deformasi dihilangkan.

The correct answer is "Membuka pintu". This is because opening a door involves pulling it towards oneself, which is an example of a pulling force or tarikan. Pushing a cart, throwing a stone, and breaking a glass all involve pushing or applying force in a different direction, not pulling.

The correct answer is "Jarum". The explanation for this is that a compass uses a magnetic needle or "jarum" to align itself with the Earth's magnetic field. The needle is usually mounted on a pivot so that it can rotate freely. One end of the needle is marked with the letter "N" for north, while the other end is marked with the letter "S" for south. As the needle aligns itself with the Earth's magnetic field, it points towards the Earth's magnetic north pole, allowing us to determine the direction of north.

The correct answer is "Pegas". The question asks for the force generated by the elasticity of an object, which is called a "Pegas" in Indonesian.

Driving a car involves changing the direction of the car by applying force or pressure on the steering wheel. This force causes the car to turn left or right, depending on the direction the steering wheel is turned. Therefore, driving a car is an example of a force that can change the direction of an object.

The correct answer is "Gaya dorong angin" (The force of wind pushing). This is because wind exerts a force on the blades of the windmill, causing them to move and rotate. The force of the wind pushing against the blades creates a pushing force, known as the "gaya dorong angin," which enables the windmill to move.

Gaya gesek dapat menimbulkan panas karena ketika dua benda saling bergesekan, energi kinetik dari gerakan benda-benda tersebut akan berubah menjadi energi panas. Gesekan antara permukaan benda-benda menghasilkan perlawanan yang mengubah energi gerak menjadi energi panas, sehingga benda-benda tersebut menjadi panas.

A dinamometer is a tool used to measure the magnitude of force. It is commonly used in physics and engineering to determine the force exerted by an object. Unlike a speedometer, which measures speed, a dinamometer specifically measures force. A meteran is a general term for a measuring tool and a penggaris is a ruler, neither of which are specifically designed to measure force. Therefore, the correct answer is dinamometer.

The statement suggests that the rougher the surface of an object, the greater the frictional force it produces. This is because rough surfaces have more irregularities and bumps, which increase the contact area between the two surfaces and therefore enhance the frictional force.

The factors that affect the motion of a falling object due to gravity are its weight, shape, and surface area. The price or value of an object does not have any influence on its motion.

The correct answer is "Gaya gravitasi." The question is asking about the force generated by the Earth's magnetic pull, and the force that is associated with this is the force of gravity. Gravity is the force that attracts objects towards the center of the Earth, and it is responsible for keeping objects on the surface of the Earth and giving weight to objects. Therefore, the force generated by the Earth's magnetic pull is the force of gravity.

Menutup pintu dari dalam ruang membutuhkan gaya dorongan karena pintu harus didorong ke arah yang berlawanan dengan arah pintu terbuka agar dapat menutup dengan rapat.

The correct answer is "Pegas" because a trampoline utilizes the force and elasticity of springs (pegas) to propel the jumper into the air. The springs absorb the impact of the jumper's body and then release the stored energy, allowing the jumper to bounce back up. Without the springs, the trampoline would not be able to provide the necessary bounce and would not function properly as a recreational device.

Kaca is the correct answer because it is known for its property of being easily malleable when subjected to force or pressure. Unlike other materials like batu (stone), kayu (wood), and bata (brick), kaca can be easily shaped or molded into different forms without breaking or cracking. This property makes kaca suitable for various applications such as in the manufacturing of windows, bottles, and mirrors.
