Speed doesn't "become" velocity. Velocity is simply speed as a vector, meaning that not only the magnitude is specified (as in the speed), but also the direction.

speed and velocity becomes equal when a body is moving on a straight road without changing its direction.

If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.

That will depend not only on the escape velocity, but also - very importantly - on the object's speed.

Terminal velocity. When the parachutes cannot fall any faster.

Velocity is speed along with the direction of the speed.

velocity is speed with direction; velocity is a vector and speed is a scalar

Remember that velocity is a vector quantity which means it needs two criteria to be defined; a magnitude, and a direction. When we discuss the magnitude of velocity, what we are talking about is the speed (30m/s, 45mph, etc). Those examples are examples of speed; it is only when we add a direction that it becomes 'velocity'. So, the difference is: "25m/s" is a speed, but "25m/s east" is a velocity. Speed (the magnitude of velocity) is calculated by taking the total displacement divided by the total time. Speed=(distance travelled)/(time it takes). Hope this helps

Speed has no direction, velocity does.

SPEED has the speed only; while VELOCITY has the direction and the speed.

Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)

Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't

Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.

yes.acceleration means change of velocity and not speed to be more precise.in a circular motion with constant speed the particle or the object constantly changes its direction.the direction of velocity is directed along the direction of the tangent at that point.although speed remains constant the velocity changes infinite number of times.so the particle is said to be accelerating.there is always instantaenous acceleration.but the average acceleration becomes zero after every round because velocity becomes the same after every round.

No. Speed has no direction. Velocity is speed anddirection.

Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed So a change in velocity means a change in speed.

That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.

It is the speed or velocity at a particular instant.
