First of all you must be familiar with scalar and vector quantities. A scalar quantity is a physical quantity having only magnitude example length. A vector quantity is a physical quantity having both magnitude and directions.
Now speed and distance are both scalar quantities which means their values are always positive. But if you considered velocity then there can be a negative value.
Velocity is measured w.r.t the direction the object is going. Conventionally the direction is negative if the object is moving to the left of the initial point and positive for the other way.

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.
Can a body have negative speedwhy?
No. The speed is the length of the velocity vector, and that is always zero or positive.
Can the speed of body be negative?
The problem here is the conflating of the term "speed" with "velocity". Velocity is a vector - it has both intensity and direction. Velocity can be negative. Speed really only has magnitude, so it is normally only positive; since there is no direction associated you can't define a meaning for negative speed (unless you decide to define it as synonymous with velocity) When a body is thrown in upward direction and upward motion is defined as positive velocity, its velocity decreases with time and at highest point speed and velocity become zero. When the body falls downward its speed i increases until hit the ground but since it is moving in the opposite of the direction that was defined as "positive", its velocity is negative.
How do you tell which battery lead is positive or negative?
The negative should lead to the frame, block, or body. The positive will lead to the starter and fuses.The negative should lead to the frame, block, or body. The positive will lead to the starter and fuses.
What does the slope of the line on a position versus time graph tell you about the objects speed?
The distance versus time graph shows the position of the object. The slope of the line shows the velocity of the object. The velocity is the direction and speed of an object. If your slope has a positive slant that means you are going in a positive direction. If the slope has a negative slant your object is going in a negative direction. If your slope is zero (a horizontal line) that means your object has stopped and is about to change directions. In case you didnt know a positive slant looks like this on a graph.... / a negative slant looks like this on a graph.... \ postive is like sloping up a hill negative is like falling down the hill
Parathyroid glands is a negative or positive feed back?
Negative. There are VERY few positive feedback mechanisms in the body- the only one i know about is birth. Think of negative feedback and positive as a line.
What impact does marijuana have on the body?
more positive than negative
How does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Your statement is for positive feedback.
How do you tell a positive wire from a negative wire on a car?
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
Do a normal person should have positive fluid balance or negative fluid balance?
Total body water is 60% of body weight, Intracellular fluid is 40% of the body weight and extracellular fluid is 20% of the body weight.
How can you get speed and distance covered by a body from distance time graph?
Distance you read off directly from the graph. Speed is the rate of increase of distance, so it is the slope (gradient) of the graph.
