What two things velocity tell us about an object's motion?
speed and direction.
What does velocity tell?
speed and deriction (;
What does velocity tell you that speed does not?
Direction.
What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
Why does velocity stay constant with decreasing momentum?
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.
How can you figure out velocity?
You check out the speed and direction, and times them together, and it will tell you the velocity of the object.
What two things velocity tell us about an object's motion?
speed and direction.
What does the speed and directiion of and object motion tell us?
The speed and direction of an object is its velocity.
What does a velocity-time graph tell us?
How the speed of something changes over time.
Is 35km per hour a speed or velocity?
35 km per hour is a speed.If you also tell us what direction it's going, then it's a velocity.
Does velocity have to be represented by north east etc?
If you call it "velocity" then you have to tell what direction it points.If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
Does speed tell us what direction an object is moving?
Speed is a scalar quantity and has only magnitude and not direction. Hence, speed cannot tell us what direction an object is moving. However, velocity which is the vector equivalent of speed, can tell us the direction.
Does a velocity graph tell you where to start?
No. It will tell you WHEN but not where.
How can you tell an object has moved?
Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
What does velocity tell?
speed and deriction (;
What does velocity tell you that speed does not?
Direction.
What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
