v = velocity of the charge . B = external magnetic field. θ = angle between the direction of motion and the magnetic field The force on a charge q as it travels with velocity v through a magnetic field B is given by this formula.
What is the value of V in physics?
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt .
What does the symbol V mean in physics?
volt (V) volume. cubic meter (m 3 ) shear force. velocity.
What does V mean in physics velocity?
We can define speed as a function of distance traveled whereas velocity is a function of displacement. Instantaneous velocity is the velocity of a body at any given time. Average velocity is the total displacement by total time and is given by v = △x△t where ∆x is the total displacement of the body and ∆t is the time.
What does V stand for in physics light?
Refraction Basics
“n = c / v” “c” is the speed of light in a vacuum, “v” is the speed of light in that substance and “n” is the index of refraction.
What does V not mean in physics?
Since the highest order is 1, it’s more correct to call it a linear function. The symbol v 0 [vee nought] is called the initial velocity or the velocity a time t = 0. It is often thought of as the “first velocity” but this is a rather naive way to describe it.
What does P stand for in physics?
| Lower case letters Upper case Letters Unit symbol | m M m = metre (length) m 2 = metre squared (area) m 3 = metre cubed (volume) | n N N = newton (force or weight) | o O NOT used for anything – it would too easily be confused with the number zero | p P Pa = pascal (pressure) |

What is V and U in physics mirror?
In a spherical mirror:
The distance between the object and the pole of the mirror is called the object distance(u). The distance between the image and the pole of the mirror is called Image distance(v) . The distance between the Principal focus and pole of the mirror is called Focal Length(f).
What is V and U in light?
Where v is the image distance and u is the object distance . Hence, the expression for magnification (m) becomes: m = h’/h = -v/u. Learn more about Reflection of Light here.
What formula is V u at?
Acceleration is the rate of change of velocity of an object. where a is acceleration, v is the final velocity of the object, u is the initial velocity of the object and t is the time that has elapsed. This equation can be rearranged to give: v = u + at .
What are the 3 types of velocity?
The different types of velocities are uniform velocity, variable velocity, average velocity and instantaneous velocity .
What is velocity example?
Velocity is speed with a direction . Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity. Imagine something moving back and forth very fast: it has a high speed, but a low (or zero) velocity.
What is velocity in physics class 11?
Velocity is defined as the rate of change of distance of the body with respect to time . ... Velocity is defined as the rate of change of displacement of the body with respect to time. Its unit in SI is [{km}/{s};]. C.) Velocity is defined as the rate of change of distance of the body with respect to time.
What does D in physics stand for?
“d” means change ... in the limit that the change is infinitestimal. in your particular exapmle: really means “average” current because that’s total change in charge over total change in time: in fact it means. , now when in the limit of very small change.... ie.
What is U in physics class 9?
u is initial velocity . v is the final velocity. a is acceleration. t is the time period.
What is refraction formula?
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
