# Can speed equal velocity?

789

###### Wiki User

Speed is the size of velocity. But velocity also has a direction.

"30 miles per hour" is speed.

"30 miles per hour north" is velocity.

For the instantaneous value of average velocity, average speed and average velocity are equal.

The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.

Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.

YES!!!!!!!!!!!! A body can have equal velocity and speed at the same time. for suppose a body is travelling at 20m/s in north direction then the speed of the body is also equal to 20m/s. hence speed and velocity are equal in this case.

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.

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

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.

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

Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.

Velocity is equal to the change in distance divided by the change in time. Speed is the magnitude of velocity

No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.

This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.

Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.

-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.

It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)

The initial speed of a given particle.

The speed and direction of an object combine to give its velocity with the speed being equal to the magnitude of the velocity.

speed is a scalar and velocity a vector. Yes, they have equal speeds in the direction of the vector. If you run up a hill at 10 mph the speed and velocity in the direction up hill are the same, but the horizontal speed and vertical speed are different.

No. Velocity is the Speed of an object, plus a component that defines its direction.

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

The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.

Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.

-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity

No. The linear velocity can never be equal when speed is constant. This is because direction is changing and therefore linear velocity changes.
