FAQ Physics Formulae

Q: What is the Class 11 Physics formula for velocity?

A: The formula for velocity is given by v = (s – u) / t, where “v” is the final velocity, “s” is the displacement, “u” is the initial velocity, and “t” is the time taken.

Q: How can I calculate the acceleration of an object using the formula?

A: Acceleration is determined using the formula a = (v – u) / t, where “a” is the acceleration, “v” is the final velocity, “u” is the initial velocity, and “t” is the time taken.

Q: What is the formula for kinetic energy?

A: The formula for kinetic energy is KE = (1/2) * m * v^2, where “KE” is the kinetic energy, “m” is the mass of the object, and “v” is its velocity.
