What will be the momentum of an object moving with a certain speed?

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.


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 is meant by positive and negative acceleration?

Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.


Can speed of a body be negative?

No. "Speed" is a scalar quantity, without sign or direction. But "velocity" can, if the object is moving opposite to the direction that you defined as the positive direction.


What is the opposite of walk?

The traditional opposite is run, indicating a different speed.To not walk is to stand, stay, or wait.Another possible opposite is crawl, which is the earlier form of moving around.


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.


When Michelson and Morley measured the speed of light in various directiion they discovered that?

... its speed is the same in any direction, even if you're movingin that direction or in the direction opposite to it.


How can you tell if two forces are unbalanced?

2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.


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.


What forces are in balance to keep a car moving at a constant speed?

The engine's force and frictional force are equal and opposite. Hence no net force and so no acceleration. That is why same speed


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 does driving overtaking and passing mean?

Coming up behind a car at a faster speed and moving around said vehicle.


Moving at constant velocity is also moving with constant speed?

Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.


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.


Which forces cause an object to move?

-- A moving object doesn't need any force to keep it moving.-- The speed, or direction, or both, of a moving object is changedby any force that's not cancelled by another equal opposite force.


Are there any forces acting on you in the direction you are moving?

Maybe, maybe not. Forces don't happen because you're moving ... forces are what cause you to move. If there are no forces acting on you, then you keep moving whichever way you're moving, and your speed or direction don't change. If there are forces acting on you, then your speed and/or direction can change. If the force is in the same direction that you're already moving, you'll move faster (accelerate). If the force is in the direction opposite to the direction you're moving, then your speed will decrease. Does any of this sound surprising ???


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.


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).


Can you use average speed to calculate the speed of an object that is moving at a constant speed?

Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.


If an object accelerates in the same direction in which it is moving how is its speed affected?

The speed of the object will increase.


What is the typical speed of moving plate?

The typical speed of a moving plate is about 21mm a year.


What is the difference between moving at a constant speed and not moving at all?

None, as "not moving at all" is just moving at a constant speed of zero. Special relativity shows that there is nothing unique or different about zero speed. It is just a value of constant speed.


What is the definition of winds?

The amount of low or high pressure in the area moving at a constant speed. also determined by where the wind is coming from(south,north).


If you are moving at the speed of light how fast will you fall apart?

If you are moving at the speed of light, then "how fast" has no meaning.
