Yes.
Scalar as it doesn't have a direction.
Scalar quantities do not have direction.
Inertia is a tensor quantity, which means it has both magnitude and direction. It is not solely a vector or scalar.
Vectors include information about their direction, and are incomplete without it. Examples are displacement, velocity, acceleration, momentum, magnetic field. (Velocity is speed with direction.) Scalars are complete without stating any direction. Examples are temperature, cost, mass, speed. (Speed is velocity without direction.)
Scalar, because no direction is used to specify the mass.
Electric current is not a vector quantity because it does not have a specific direction associated with it. It is a scalar quantity that represents the flow of electric charge through a conductor. The direction of current flow is defined by the convention of positive charge flow from higher potential to lower potential.
The future tense for speed is will speed.
there's four speed. There are constant speed, average speed, increasing speed, and decreasing speed. choose one of them
No instantaneous speed is not final speed.
Walking speed Bicycle speed Automobile speed Train speed Airplane speed Rocket speed
Perhaps coincidentally, the phrase "light speed" refers to a speed.It is a speed.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
