Velocity is a vector.
Its magnitude is called 'speed'.
Speed is the rate of which an object is moving altogether and is a scalar quantity and thus only requires a magnitude and is found by the use of the formula speed=distance/time SI unit = m.s-1 Velocity is the rate of which a object is moving in a given direction, so is vector quantity and both a magnitude and direction are required found by the formula velocity=displacement/time SI unit = m.s-2
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
Gravity is a force, and forces have magnitude and direction; hence, it is a vector.
A vector quantity has both size (magnitude) and direction involved but a scalar quantity only has size involved and not direction.
no, it's a vector dude
Instantaneous velocity is a vector quantity.
I think Scalar
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.
"Speed" is a scalar; "velocity" is a vector.
No, a vector quantity and a scalar quantity are different. A vector has both magnitude and direction, while a scalar has only magnitude. Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities.
... a vector quantity. Speed is a scalar, meaning only the magnitude (a number) is used. If the direction of a movement is of interest, you use the word "velocity", instead, to describe the vector. A vector has both a magnitude and a direction.
Velocity is a vector quantity because it includes both the speed of an object and its direction of motion. Speed is a scalar quantity because it only represents the magnitude of motion without direction.
Acceleration is a vector quantity because it has magnitude (amount of change in velocity) and direction.
A scalar quantity defines only magnitude, while a vector quantity defines both a magnitude and direction.
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
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.
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
