Physics Formulae

What is the formula for speed?

Speed = distance / time (measured in m/s).

What is the formula for acceleration?

Acceleration = (final velocity - initial velocity) / time (measured in m/s²).

What does the equation v = u + at represent?

It represents linear motion with constant acceleration.

What is the formula for displacement in terms of initial velocity and acceleration?

Displacement s = ut + ½at².

What is the conservation of momentum in a closed system?

Total momentum before impact = Total momentum after impact.

What is the relationship between force, mass, and acceleration?

Force = mass x acceleration (measured in Newtons).

What is the formula for weight?

Weight = mass x acceleration due to gravity (measured in Newtons).

What is the angular velocity formula?

Angular velocity w = angle in radians / time.

How is centripetal force calculated?

Centripetal force F = mv² / r.

What is Boyle's Law?

Pressure is inversely proportional to volume for a fixed mass of gas at constant temperature.

What is the equation for simple harmonic motion?

F = -ks (where k is the spring constant and s is the displacement).

What defines the periodic time of a simple pendulum?

T = 2π√(L/g) where L is the length and g is the acceleration due to gravity.

How do you convert Kelvin to Celsius?

t = T - 273.15.

What is the relationship between electric field strength and charge?

Electric field strength E = F / Q, where F is the force and Q is the charge.

What is the formula for energy stored in a capacitor?

Energy = ½CV², where C is capacitance and V is voltage.

What does Faraday's law state about induced EMF?

Induced EMF = -N (dϕ/dt) where N is the number of turns in the coil.
