What does instantaneous velocity mean?
Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is velocity a vector or scalar quantity?
vector QUANTITY vector QUANTITY
Is velocity an exampleo a vector quantity?
Yes, velocity is a vector quantity.
Why angular velocity is vector quantity?
Because it's a type of velocity and velocity is vector quantity
Is angular velocity a vector quantity?
Yes, angular velocity is a vector quantity
What vector has a magnitude equal to instantaneous speed?
the velocity vector
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
Is velocity a scalar quantity or vector quantity?
velocity is a vector quantity because it`s formula is displacement by time and displacement has a particular direction. that`s why velocity is a vector quantity but speed is a scalar quantity
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Is momentum a vector or scaler quantity?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
Is momentum a vector quantity because it includes velocity which is also a vector quantity?
yes, momentum is a vector quantity.
Is velocity a vector or a scalar?
Velocity is a vector quantity or simply vector, it has both magnitude an direction.
Is velocity a vector?
True ,velocity is a vector quantity ,it is specified by a magnitude and direction.
Is velocity a vector or a scalar quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
Does a speedmeter give instantaneous speed or velocity?
Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.
Is velocity a vector quantity?
Yes, velocity is a vector quantity since it can be defined by both magnitude and direction unlike speed.
Momentum is defined as?
The product of velocity and mass. Note that velocity is a vector quantity, therefore momentum, too, is a vector quantity.
Which measurement is a vector quantity?
A vector quantity measures the movement of a particular object in a given direction. An example of a vector quantity is velocity.
Is moment a vector or scalar quantity?
A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
Why Is the magnitude of instantaneous velocity always equal to the instantaneous speed?
Because speed is the magnitude of the velocity vector. The velocity consists of the speed and the direction, and the whole thing can be embodied in a 3D vector. If you like the velocity is the magnitude (the speed), which is a scalar (just a real number), multiplied by a unit vector in the right direction.
Why is speed a vector quantity?
Speed is not a vector quantity, because it has no direction. When you combine speed with a direction, then you have a vector, called "velocity".
Does a car speedometer measure velocity?
No, 'speed'ometers in cars measure instantaneous speed, which is a scalar quantity. Velocity is a vector quantity, and it is speed plus a direction vector. An example of speed might be 55 miles per hour, while an example of velicity might be 55 miles per hour to the east.
