How two things do you need to know to describe the velocity of an object?
Velocity includes speed and direction.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
What two things do you need to find an objects velocity?
Change in position and change in time velocity= delta displacement/delta time
What three things do you need to know to determine velocity?
you need to know two different positions for the moving object, and the time interval between them. Velocity is the time it took to go from point A to point BTechnically, tho- you only need two things... Distance traveled and time.
What is the wavelength of a wave that has a velocity of 0.4 and a frequency of 0.2 Hz?
you need to specify the units for velocity. assuming that the velocity is in metres per second, the wavelength is 2 metres
What two things do you need for velocity?
The 2 things are speed and distance.
How two things do you need to know to describe the velocity of an object?
Velocity includes speed and direction.
What to Things do you need to know to describe the velocity of an object?
velocity is what is known as a vector quantity. What this means is it needs both a DIRECTION and a MAGNITUDE for the velocity to be fully described. that's what you need.
What 2 things must you know to descriobe the motion of an object?
If movement is in two dimensions: the x-coordinate of the velocity, and the y-coordinate of the velocity. Or alternatively: the magnitude of the velocity, and the direction. If movement is in three dimensions, you need to know three things, for example, x-coordinate, y-coordinate, and z-coordinate of the velocity, or magnitude of the velocity and two components of direction.

What 2 things keep something in orbit around the earth?
Mass & Velocity .
What 2 things keep your planets in an elliptical orbit?
Gravity and velocity (or inertia), and they aren't things. They're forces.
What is the wavelength of a wave that has a velocity of 0.4 and a frequency of 0.2 Hz?
you need to specify the units for velocity. assuming that the velocity is in metres per second, the wavelength is 2 metres
A braking time of 1.5 to 2 seconds what is the final velocity?
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
What information do you need to determine velocity?
You need to have displacement and time for you to determine the velocity.
