Because a vector contains information about the direction. A direction, at any particular position is the tangent to the curve and this, by definition, must be straight.

The status to Hilbert's problem remains unresolved.
If you translate (move without rotation) a copy of the line towards the curve, the first point where the line touches the curve (the tangent to the curve with the slope of the original line) will be the point on the curve closest to the line. Draw a connecting line from this tangent point to the original line, intersecting that original line at right angles. Measure the connecting segment. It is the shortest distance. Vector analysis will give a mathematically strict solution, I do not have the ability to explain this in sufficient detail.
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Vectors can be added together graphically by placing the head of one vector at the tail of the other vector. The slope of a line tangent to a curve indicates instantaneous velocity.

You mean "can light waves travel in nonstraight lines?"? Yes, if they are diffracted or pass through different materials. Gravity can also affect light waves and curve them.
After leaving the gunbarrel, the only force preventing straight line motion is gravity, the result is (apart from firing straight up) a flight path in the form of a parobolic curve. Using the launch angle and velocity, break into horiontal and vertical velocity vectors. Horizontal velocity vector is contant horizontal velocity. Vertical velocity vector will obey newtons laws up and down Using time intervals, you can plot the curve.
A line integral can evaluate scalar and vector field functions along a curve/path. When applied on vector field, line integral is considered as measure of the total effect of the vector field along a specific curve whereas in scalar field application, the line integral is interpreted as the area under the field carved out by a particular curve.Line integral has many applications in physics. In mechanics, line integral is used to determine work done by a force in moving an object along a curve. In circuit analysis, it is used for calculating voltage.
Actually, a car always accelerates on a curve. This is because acceleration, like the velocity it alters, is a vector that has both magnitude and direction. Since taking a curve involves a change of direction, there must be an acceleration to alter the direction; otherwise, the car can only continue straight.
