What is the formula for kinetic energy?
Answer: The formula for kinetic energy is KE = 1/2 mv^2, where m is the mass of the object and v is its velocity.
What is the speed of light in a vacuum?
Answer: The speed of light in a vacuum is approximately 3.00 x 10^8 m/s.
What is the principle of conservation of energy?
Answer: The principle of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
What is the unit of power?
Answer: The unit of power is Watt (W).
What is the formula for Ohm's law?
Answer: Ohm's law states that V = IR, where V is voltage, I is current, and R is resistance.
What is the difference between longitudinal and transverse waves?
Answer: Longitudinal waves move in the same direction as the wave, while transverse waves move perpendicular to the direction of the wave.
What is the formula for gravitational force between two objects?
Answer: The formula for gravitational force between two objects is F = G (m1m2/r^2), where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.
What is the unit of electric charge?
Answer: The unit of electric charge is Coulomb (C).
What is the difference between conductors and insulators?
Answer: Conductors allow electricity to pass through them easily, while insulators do not allow electricity to pass through them easily.
What is the formula for acceleration?
Answer: The formula for acceleration is a = (v2 - v1)/t, where v2 is the final velocity, v1 is the initial velocity, and t is the time taken.
What is the difference between mass and weight?
Answer: Mass is the amount of matter in an object, while weight is the force of gravity acting on an object.
What is the formula for work done?
Answer: The formula for work done is W = Fd, where W is work, F is force, and d is distance.
What is the difference between static and dynamic friction?
Answer: Static friction occurs between stationary objects, while dynamic friction occurs between moving objects.
What is the formula for pressure?
Answer: The formula for pressure is P = F/A, where P is pressure, F is force, and A is the area over which the force is applied.
What is the difference between heat and temperature?
Answer: Heat is the energy transferred between two objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in an object.
What is the formula for potential energy?
Answer: The formula for potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
What is the difference between series and parallel circuits?
Answer: Series circuits have all components connected in a single path, while parallel circuits have components connected in multiple paths.
