Answer:
1 - Gravitational.
2 - Normal
3 - Tension
4 - Frictional
5 - Centripetal
Step-by-step explanation:
1. If you drop something, gravity pulls it down to the Earth, So falling towards the earth is gravity.
2. Pushing back on another object is normal, Newton's law: Every action has an equal and opposite reaction.
3. When two forces are pulled on opposite sides, the object must stretch which creates tension. Think of a rubber band. If it is pulled more than the object can stretch, it will tear. Tensile strength refers to how much pulling force an object can withstand before it tears.
4. When objects or molecules rub against other objects or molecules they create friction.
5. Last two options go together.
