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.
What is relative speed?
Relative speed is the speed between two moving objects with no regards to a fixed reference. Speed is how fast something is moving with respect to an object.
Can speed be treated as force in direction and opposite speed?
Speed and force are quite different things.
How is speed and velocity the same?
No, they are not the same! Velocity involves the speed and the direction of the moving object...

How friction decreases d speed of an moving object?
friction is nothing but just the opposite force acting on any moving object...... it hence decreases the speed of a moving object as the object is obstructed in its path
What happens when a balanced pair of forces acts on a single object?
When all forces are balanced, the object is either stationairy or moving in one direction inTekkit - Episode 2 a constant speed
Does friction cause the speed of moving objects to increase?
No, the force of friction always acts in the direction opposite to that of the motions.
Looking at the ground beside a moving vehicle ensure that the are off?
Looking at the ground beside a moving vehicle ensures you see if they are coming into your lane or not.
How does force make an object stop moving?
By accelerating it in the direction opposite to its motion, and then quickly removing the force when it's speed is zero.
What is a momentum of an object of mass 'm' moving the velocity v?
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
What does driving overtaking and passing mean?
Coming up behind a car at a faster speed and moving around said vehicle.
If a police car is moving in the opposite direction of your car can he get an accurate speed of your car?
oh yes, the radar guns are attached to the cars internal computers, so it compensates for the forward speed.
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
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.
Two cars moving in opposite directions with same mass and speed and in what direction and what speed does the wreckage move?
If they collide head on, the wreckage will remain at the point of impact (real world considerations aside).
