What is formula for speed?
Velocity is equal to the change in distance divided by the change in time. Speed is the magnitude of velocity
When is speed equal to magnitude of velocity?
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.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
Is momentum equal to the mass of an object divided bi its velocity?
No, momentum is not equal to the mass of an object divided by its velocity.
When do the velocity and speed of moving body become 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.
Can a body have velocity and speed equal?
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.
Why is the absolute value of velocity equal to speed?
Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.
When is speed equal to the magnitude of velocity?
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.
Acceleration is equal to what?
Answer: speed divided by time Answer: Acceleration = dv/dt, that is, the rate of change of velocity, with respect to time. In other words, how fast does velocity change.
When do speed and velocity become equal?
speed and velocity becomes equal when a body is moving on a straight road without changing its direction.
What are the difference between speed and velocity?
Speed is distance divided by the time taken Velocity is distance in a particular direction divided by the time taken. Velocity is a vector quantity while speed is a scalar quantity. That means that velocity include information about the direction of movement, while speed does not.
What is acceleration velocity and speed?
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
Is acceleration equal to initial velocity minus the final velocity divided by the time?
No, It is the average velocity.
Can speed equal velocity?
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.
Is speed equal to velocity?
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.
What is the scientific definiton of speed?
Speed is the magnitude of velocity, with units of distance divided by time. An important distinction is that speed is a scalar and velocity is a vector. Consequently, speed (unlike velocity) does not have a direction.
Under what conditions is the magnitude of average velocity of an object equal to its average speed?
The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.
Is average velocity vector or scalar quantity?
no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.
Is velocity equal to speed?
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.
How do you calculate the velocity of a mass?
Speed divided by time.
If two objects have different speed can they have the same 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.
Why is the value of velocity equal to speed?
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
How do you get velocity?
velocity is speed plus a direction. velocity can be expressed mathematically as V=t/d. velocity=distance divided by time.
Why is average speed distance divided by time but average velocity is initial velocity plus final velocity divided by 2?
Because velocity is a measurement of change of speed rather than an average constant speed. To get the average speed (as you rightly said) - you divide the total distance travelled by the time taken. The average velocity is the change in speed over time (either an increase or decrease).
Expressed as the distance divided by time?
Speed or velocity can be expressed as the distance divided by time.
