When the velocity is zero at the crossing of the time axis, the displacement must be a full maximum or minimum. Scroll down to related links and look at "Displacement - Velocity- Acceleration".

No, you cannot have a zero displacement and a nonzero average velocity. If the object has not moved any where how can you attain a nonzero velocity? You cannot.

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)

The averagevelocity v of an object moving through a displacement during a time interval is described by the formula:

There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.

No. Displacement is the change in location or position.

It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".

Not so. Displacement is the change in position or location. Change in velocity is referred to as "acceleration".

it can be calculated at a particular instant as it is total displacement in given time

work is the product of force and displacement As velocity is rate of change of displacement, so yes, velocity does effect work.

the displacement is zero.Note that distance travelled would not be zero though. as velocity doesn't signify anything abt distance travelled.speed will give you what distance you travelled.Since average velocity is zero, some component is negetive some positive or no movement at all. whichever case may be, the displacement will be zero.

Speed is a scalar quantity that refers to how fast an object is moving. Speed can be thought of as the rate at which an object covers a distance. While velocity is a vector quantity that refers to the rate at which an object changes its position. But when we calculate speed and velocity what we get is average not instantaneous. Average Speed= Distance travelled ------------------------ Time period Average Velocity= Displacement ------------------------ Time period

Speed is distance by time and velocity is displacement by time. If an object is moving with speed distance can never be zero but displacement can. So we say velocity can be zero.

speed,displacement and velocity.

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.

If the average velocity is 5.2 m/sec. then it means that the moving object undergoes a displacement of 5.2m in a time interval of 1 sec. along a particular direction. If the average velocity is 5.2 km/hr. then it means that the moving object undergoes a displacement of 5.2km in a time interval of 1 hr. along a particular direction. Thus depending upon the unit used, the description will be different.

Displacement and Time, displacement is the distance with a direction ( vector quantity) , and time . Displacement and velocity are directly proportional, while velocity and time are inversely proportional..( The faster, the less time it will take) Velocity = Displacement ____________ Time

A change in the position of an object is called a displacement. Velocity is the measure of the rate of change of displacement with respect to time.

It's as simple as total displacement divided by total time. Be careful though. If this is a velocity problem, displacement does not always equal distance.

When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.

The average amount of motion can be determined by the average speed or velocity of an object. The average speed can be calculated by the total distance divided by the total time. Speed is a scalar quantity. The average velocity can be calculated by the total displacement divided by the total time. Velocity is a vector.

first of all the question should come with velocity instead of speed. it doesn't necessarily mean that displacement is doubled the time in which the object makes that displacement is halved

The difference between speed and velocity is, that speed is the rate of how much an object in motion can get to and how much distance it can cover. Velocity is the motion on how far an object will go and how far it will take to get there. Speed is the rate of the change of distance over time Speed equals distance over time. Velocity is the change of rate of displacement with time velocity equals rate over time. The more speed that a object time to reach a distance, the less time it will take, the less speed to reach a object then the more time it will take to get there. Displacement is measured in the shortest path so the Magnitude is always equal to or less than the distance. The average velocity averages the object speed as the object approaches zero. Velocity is the vector of a object and the speed is the rate of movement. Speed is referred to how fast a object can reach in a period of time while velocity is which the object will change in position, both speed and velocity are calculated in the same units. Speed and velocity are both measured in the same units(km/hr)kilometers per hour or (m/s)meters per second. Velocity is a vector and Speed has a Scalar which is magnitude, velocity can also be the speed and the direction of a object. -plz 2kil u
