what is difference between speed and velocity and between distance and displacement?

Question

Answer

velocity is a vector quantity which have both magnitude as well as direction and speed is scalar quantity having only magnitudedisplacement is change of velocity per unit timedistance is Define as final point - initial point in particular time interval

Answer

velocity has direction while speed has no direction and same is for distance and displacement

Answer

speed the distance travelled per unit time and it is scalar quantity which means that it has only magnitude. velocity is the rate of change of displacement and it is vector quantity in which it has both magnitude and direction. Distance is the actual path of the object and Displacement is the shortest distance between initial positions to final position.

Answer

spped is scalar quantity and velocity vector...speed has no direction but velocity has....distance means the total path covered...displacement means the shortest distance between two points.....displacement is a vector quantity whereas distance is scalar

Answer

speed is rate of change of displacement but velocity is rate of change of speed. distance is total path followed by a body and displacement is the nearest distance between starting and final position of the object.

Answer

Speed vs Velocity:
- Speed is a scalar quantity that only considers the magnitude of an object's motion, indicating how fast an object is moving. It is measured in units like meters per second or kilometers per hour.
- Velocity, on the other hand, is a vector quantity that considers both the magnitude and direction of motion. It specifies the speed and direction of an object's movement, making it more descriptive than speed.

Distance vs Displacement:
- Distance is a scalar quantity that measures the length of the path covered by an object in motion. It is always positive and represents the total length traveled, irrespective of direction.
- Displacement is a vector quantity that measures the change in position of an object in motion. It considers the shortest path between the initial and final positions, taking into account direction and magnitude.

Distinguishing Factors:
- Speed and velocity differ in that velocity includes direction, while speed does not.
- Distance and displacement differ in that displacement considers the change in position, while distance only considers the total path traveled.
- Speed and distance are scalar quantities, while velocity and displacement are vector quantities.
- Speed and distance are always positive, while velocity and displacement can be positive, negative, or zero based on direction and position changes.
In summary, the key distinction lies in the consideration of direction in velocity and displacement, making them more informative than speed and distance, which only provide magnitude information.

Answer

in

Answer

velocity: 1) rate of change of Displacement ( Displacement÷time)2) it is a vector quantityspeed: 1)distance travelled÷time taken2) it is a scalar quantity

Answer

speed is scalar. therefore no need to mention direction  while defining. and vice-versa

Answer

nothing understood

Answer

In straight line motion speed and velocity are same because  in A straight line distance and displacement are same .
