Which of the following best describes the relationship between force and an object's properties?
Which of the following best describes the relationship between force and an object's properties?
- Force can alter an object's physical properties such as shape, position, and motion. (correct)
- The color of an object can change when any kind of force is applied on it.
- Only the size and hardness of an object are affected by force; shape and flexibility remain constant.
- Force only affects an object's motion, not its physical properties.
Why is clay commonly used in pottery, according to the text?
Why is clay commonly used in pottery, according to the text?
- Clay can easily change shape when a force is applied, which is useful for making pots and vases. (correct)
- Clay retains its original shape regardless of the force applied.
- Clay is useful for maintaining stability and preventing deformation in pottery products.
- Clay is resistant to changes in shape and size.

What is a key difference between how a sponge and metal respond to being squeezed?
- Metal returns to its original shape more quickly than a sponge after being squeezed.
- A sponge returns to its original shape, while metal tends to retain its deformed shape. (correct)
- Both sponge and metal return to their original shape after being squeezed.
- Neither sponge nor metal can be squeezed.

Study Notes
- Force refers to a push or pull.
- Forces in the environment have different effects on objects.
- Forces affect the physical properties, position, and motion of matter.
- One effect of force is a change in an object's shape or size.
- Solid objects have unique physical properties such as shape, size, hardness, flexibility, and mass.
- These properties can change when objects are pulled, pushed, stretched, twisted, bent, or squeezed.
Clay
- Clay can be molded into different shapes and sizes by pulling, stretching, pressing, or twisting it.
- Clay is used in pottery to make pots, vases, bowls, and other pottery products.
- Hammering metals into various forms is another example of a change in shape.
Sponges and Metal
- A sponge temporarily changes in shape and size when squeezed, but returns to its original shape when released.
- The ease of changing an object's shape and size depends on the material.
- Clay and sponge are soft materials that change shape easily when force is applied.
- A sponge is a resilient material that returns to its original form after being squeezed.
- Metal is a rigid material that does not change easily in shape, form, or size.
- A greater amount of force is required to change the structure of metal.
- Heat softens or melts iron or other metals during hammering to change them into different shapes and sizes.
