If clear is transparent what is opaque?
Opaque refers to an object or material that does not allow light to pass through, thus preventing the visibility of what is on the other side. The opposite of clear, opaque objects are not see-through or transparent.
How do you find the net force of two objects acting in the same direction?
To find the net force of two objects acting in the same direction, simply add the individual forces together. The net force will be the sum of the individual forces acting on the objects.
Does gravity affect an object without mass?
No, gravity does not affect an object without mass because gravity is the force of attraction between objects that have mass. Objects with mass create a gravitational field, which can affect other objects with mass, but objects without mass do not create a gravitational field and are not affected by gravity.
Where would you find a wedge?
You can find a wedge in various forms such as in woodworking tools like chisels and axes, in geometry as a simple machine to split or lift objects, or in footwear as a type of shoe with a wedge-shaped heel.
Where might you find upthrust acting?
Upthrust, also known as buoyant force, acts on objects submerged in a fluid (liquid or gas), pushing them upward. It is a result of the pressure difference between the top and bottom of the submerged object. You would typically find upthrust acting on objects floating or submerged in water, such as boats, submarines, or objects in a fish tank.
