# Can be calculated if you know the distance that an object travels in one unit of time?

The velocity of the object. Velocity involves direction as well as size (the concept of speed does not involve direction)

e.g. I can drive round a roundabout at a constant speed of 30 m.p.h., but in doing so my direction continually changes, so my velocity keeps changing

### What is the distance an object travels in a certain amount of time?

Velocity is distance/time, v=d/t, it can be measured in meters per second, km/h, miles per minute, etc. If you know two of the values of the equation, you will be able to calculate the third, all you have to do is rearrange the variables. So if you know the speed of the object, assuming it is constant, and the time it travels, you can figure out the total distance it has moved. Simply multiply both…

### How do you find the distance an object overtakes another object from a starting point?

Start by determining the time it takes for the one to overtake the other. To do this, take the distance between the starting points and divide by the difference in the speeds. Knowing now the time it takes to overtake, multiply it to the speed of either object (making sure to correct for different units) to know how far it travels in that time.

### How do you know a object's speed and velocity?

To determine the speed of an object, one has to know the distance the object has traveled (in meters) and the time it has taken for the object to travel that distance (in seconds). To calculate speed, take the distance traveled and divide it by the time. To determine velocity, simply take the speed and determine which direction the object was travelling.

### When you know both the speed and direction of an object's while it is in motion do you know the distance the object has traveled?

No. For you to know the distance you need to know the time the object has been travelling and a function describing the speed of the object for the time it has been travelling. A direction is not required. correct but you missed direction can affect speed as climbing altitude would get slowed by gravity

### How do they know that light takes 8 minutes to reach the earth?

Sunlight takes about 8.3 minutes to reach the Earth. The time can be calculated by dividing the distance the Sun is from the Earth (150 million kilometres) by the speed at which light travels (299,792.458 km per second) which will give you the time light takes to travel from the Sun to the Earth in seconds. We know that light travels at 186,000 Miles/s or appx 300,000km/s If we know the distance of an object…

### How do you calculate radiographic Diagnostic film length?

do you know about Penumbra calculation as its calculated from this? Ug=FxT/D Ug=Geometric Unsharpness F= Source or Window Size T= Object Thickness D= Distance from source to the front surface of the Test Object. Your Diagnostic film length is calculated from this. Depending on what standards you work to they will tell you how many shots to do on what thickness of material as well as distance shot from. there is a chart that can…

### When finding net force why must you know the directions of the forces acting on an object?

In order to find the Net forces, you need to know the X, Y and Z component of the object since their vectors(unit of distance and direction) are used to calculate the magnitude and direction of the object.... for example, if an object moves 3m in the X-axis and 4m in the Y-axis, then the net distance is 5m with an angel of tan(@)=4/3... Thus we know the distance and direction of the object... This…

### How tall will something appear to be . If we know actual height and distance the object is from you?

### Why is Hubble's law important?

Hubble's Law states that the receding velocity of an object A, with relative to object B, is directly proportional to the distance between the two objects. It allows us to calculate the speeds of celestial bodies with respect to Earth, given that we know the distance to that object(which can be found by using Doppler's Red Shift).
