when the oppotunity cost is a constant the PPF will be a stright line
A straight line has no vertex.
Displacement of a straight line is zero...
There are 180 degrees on a straight line.
The straight level line is said to be horizontal.
No. An angle of 180o is a straight line.
If the opportunity cost is constant, the PPF is a straight line; when the opp. cost of a good rises when it is produced more, then concave.
The Production Possibility Frontier (PPF) becomes a straight line when the opportunity cost of producing one good over another remains constant. This typically occurs when resources are perfectly substitutable between the two goods, meaning that the trade-off between them doesn't change regardless of the quantity produced. In contrast, a curved PPF reflects increasing opportunity costs, where reallocating resources leads to a less efficient trade-off.
A Production Possibility Frontier (PPF) is a straight line when the opportunity cost of producing one good over another remains constant. This typically occurs when the resources used in production are perfectly adaptable to both goods, meaning that shifting resources from one product to another does not change the efficiency of their production. In such cases, the trade-offs between the two goods are linear, reflecting a consistent rate of substitution.
Operating at an inefficient point, i.e. inside the PPF and not on the edge or line of the PPF

That the force that causes the acceleration is not constant.

Gravity. Things naturally travel in a straight line unless another force acts on them. The moon would travel in a straight line but is dragged down by the gravity of the earth. This constant acceleration towards the earth causes it to orbit the earth in a curve.
Light travels in a straight line until it encounters a medium that causes it to bend or change direction, such as air, water, or glass.
Yes, sound waves can move in a straight line. When sound waves propagate through a uniform medium, they usually travel in a straight line until they encounter an obstacle or medium that causes them to reflect, refract, or diffract.
The property of light to travel in a straight line is known as rectilinear propagation. This means that light travels in a straight path until it encounters an obstacle or medium that causes it to change direction.
Inertia causes a moving object to continue moving in a straight line at a constant speed unless acted upon by an external force.
