Can velocity speed up an object?
Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed So a change in velocity means a change in speed.
Why can velocity be positive or negitave?
Velocity can be a positive or a negative because velocity is a vector, which means it is also affected by direction. This that if one car is going +10 m/s and another is travelling at -10 m/s, this means that they are travelling the same speed in opposite directions.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
What is the link between velocity and acceleration?
I'm not quite sure what you're asking, but.....An object that is accelerating simply means that that object's velocity is changing. It can be increasing (positive accel.) or decreasing (negative accel.). If the acceleration is zero, that means the velocity is constant.(Keep in mind that these are all vector quantities, so they will have directions as well as magnitudes, and the positive/negative may be reversed.)
What is the physical meaning of a negative average velocity?
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).

How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.

What is the action of an automobile if the velocity is positive and the acceleration is zero?
It means the automobile is travelling at a constant speed in a particular direction.
What is the physical meaning of a negative average velocity?
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
Why two objects move in opposite direction one will have positive momentum and other negative momentum?
Quite simply, this means that momentum is a vector quantity; the direction is relevant. This is useful, for example, for calculations involving the conservation of momentum. Actually momentum is the product of velocity and mass, and velocity is also a vector quantity - thus, in this example, one object will have a positive velocity (more precisely: a positive component of the velocity along the x-axis, for example), the other, negative. Multiplying this velocity by the mass will also give a quantity which may be positive or negative (or rather, have positive or negative components).
Why acceleration is rate?
Acceleration means how fast velocity changes. "How fast" means change of velocity per time unit - and this is also called a "rate".Acceleration means how fast velocity changes.
